Draft Feral Peafowl Management Plan 2018 - 2023 1. Introduction Following the peafowl trapping and relocation program in 2015, the ACT Government made a commitment to implement a more strategic approach to the management of the ACT’s peafowl populations. This draft Feral Peafowl Management Plan (the Plan) has been prepared by the ACT Government to address ongoing concerns from the community about feral peafowl. The draft Plan is consistent with the Animal Welfare and Management Strategy 2017- 2022 and in particular supports action 3.1.5: “Develop policies and where necessary revise regulations to manage domestic animals other than companion animals in urban areas.” Issues raised by members of the public include traffic safety, noise, droppings and damage to property. To date, residents in the Narrabundah area have been most affected by peafowl although a small population of peafowl has also been identified in Pialligo. The ACT Government has considered a range of management options, as discussed in this Plan, and has determined that the best option for the ACT is to implement an annual trapping program to reduce the feral peafowl numbers with the removal of all feral peafowl being the desired outcome. The success of this Plan will be largely dependent on community support. This Feral Peafowl Management Plan has been prepared for use by the ACT Government in the management of feral peafowl on public land in the ACT. It has been developed in consultation with key stakeholders and provides a strategic approach to managing feral peafowl populations in the ACT. This Management Plan: 1. identifies and considers the social, environmental and economic impacts of the ACT’s peafowl populations; 2. provides a context for the management of peafowl in the ACT; 3. recognises that the management of feral peafowl is the shared responsibility of both the ACT Government and the community; 4. addresses animal welfare issues; 5. provides actions for managing the peafowl over the next five years; and 6. responds to the changing environment. The ACT Government will trap and remove peafowl where they occur on public land and relocate them where possible. If there are no suitable re-homing options available the birds will be trapped and humanely euthanised (see Sections 6 and 7 for details). A trapping program, to be undertaken each year prior to the breeding season, will aim to remove all peahens (females) and peacocks (males) over a number of years. Consideration was given to maintaining a small population of non- breeding peafowl (i.e. males only) to satisfy the sector of the community that liked having a population of peafowl in the area, particularly the colourful males. However, the males become noisy during the breeding season and this would lead to further negative impacts on residents. The management of non-declared pest species (including peafowl) on private land is generally the responsibility of residents and/or lessees. The ACT Government may agree to assist in the trapping and/or removal of peafowl in some circumstances. All treatments of the peafowl and their eggs must be in accordance with animal welfare requirements. 1
Draft Feral Peafowl Management Plan 2018 - 2023 2 Purpose and objectives Purpose The purpose of the Feral Peafowl Management Plan is to set out the approach to be adopted in managing the feral peafowl population in the ACT in order to address the negative impacts these birds have on the community, the environment and the economy. Objectives The objectives of the Feral Peafowl Management Plan are to: 1. address community concerns about the negative impacts of feral peafowl in the ACT; 2. prevent the feral peafowl population from spreading and impacting on other areas, including nature reserves. These will be achieved by trapping and removing feral peafowl periodically until all peafowl have been removed. 3 Consultation In preparing this plan, the ACT Government consulted with a range of stakeholders including relevant ACT Government staff, the RSPCA, residents of Wylie and Brockman Streets, Narrabundah, the management of the St Aiden’s Court Retirement Village and the broader ACT community. To insert following consultation - Summary of outcomes 4 Background 4.1 Origin The Indian Peafowl (pavo cristatus) is a member of the pheasant family and is native to India and Pakistan 1. Peafowl were deliberately introduced to Australia in the 1800s. It is likely that the feral peafowl population in Narrabundah originated from small number of peafowl that either escaped, or were released, from a now closed animal park located on Mugga Lane in Symonston. These birds, or their offspring, predominantly reside in Narrabundah however there have been reports of sightings of individual birds in nearby Griffith and Red Hill. There is also a small population of peafowl in Pialligo, in the vicinity of the garden centres on Beltana Road. The origin(s) of this peafowl population is unclear, however, it is thought that it may have originated from pets that have either escaped or been released. These are primarily located on private land. 4.2 Biology and Behaviour 4.2.1 Terminology Whilst the term ‘peacock’ is commonly used interchangeably when referring to male and/or female birds, ‘peafowl’ is the correct terminology when referring to populations of both sexes. The male peafowl are ‘peacocks’, the females are ‘peahens’ and the 1 National Geographic http://animals.nationalgeographic.com/animals/birds/peacock/ (Accessed 14 January 2016) 2
Draft Feral Peafowl Management Plan 2018 - 2023 young are ‘peachicks’. A group of peafowl is referred to as a party, ostentation or a muster. 4.2.2 Social habits Peafowl are forest birds that forage on the ground during the day and roost in tall trees at night. Peacocks (males) tend to roost alone or in groups. At the end of their second year young males leave the roosting sites of females and young to roost with other males or alone. Females with young less than four months old roost separately from other peafowl. Peafowl descend from roost trees within the first two hours of dawn, and ascend to their roosts about half an hour after sunset. Peafowl are most active in the early morning and during the last two hours of daylight when they forage for food. Peacocks and peahens flock together outside of the breeding season but during the breeding season adult peacocks spend the majority of their day in display areas (see Section 4.2.5). 4.2.3 Physical features Peacocks (males) are admired for their iridescent green and blue long tail covert (the train), which is made up of elongated upper-tail covert feathers bearing colourful ‘eyespots’ or ocelli 2. The peacocks develop ornamental tail coverts in the breeding season. The females (peahens) lack the bright colours and do not develop the long upper tail coverts. Both sexes have crests on their heads. The peacocks are between 2 - 2.5 metres in length when in full plume (the tail covert can measure up to 1.4 metres long). Peahens are smaller at around one metre in length. The male call is a series of repeated crowing ‘ka’ and shrill ‘eow’ calls of varying frequency given up to eight times in a row, primarily during the breeding season. Other distress and warning calls are given throughout the year. The females use clucking calls when with young and when pointing out food. Peafowl live for around 20 years in the wild. 4.2.4 Diet Peafowl are omnivorous and their diet includes seeds, fruits, flower buds, shoots, invertebrates and small vertebrates (i.e. small mammals and reptiles). 4.2.5 Breeding In the ACT the peafowl breeding season is from September to January. The peacock’s train, which makes up around 60 percent of its total body length, is used during mating rituals and courtship displays to attract females. The long train is moulted at the end of each breeding season. Peacocks develop their first train in their second year but it is not as long as that of a full-grown male and lacks the ocelli. The tail gets longer and more vibrant each year after that until the age of five or six when the trail reaches its maximum splendour. 3 2 Schwartz L.D., 1994 in Landcare Research New Zealand Ltd., Options for controlling peafowl (Pavo Cristatus) in New Zealand (2011) 3 New Zealand Birds Online http://nzbirdsonline.org.nz/ (accessed 13 December 2015) 3
Draft Feral Peafowl Management Plan 2018 - 2023 The peacocks open the tail covert into a fan and do a complex dance to attract peahens. As part of the courting ritual the tail vibrates, making a rattling sound. Peacocks display in an expanded lek which consists of several males in vocal contact but out of view of each other. Groups of peahens visit the lek, compare the males’ physiques and courtship displays and choose the most attractive male as their mate. It is thought that the female chooses her mate based on the size and colour of their feather trains. 4 Peacocks are polygamous and do not play any role in raising the chicks. Peahens nest in shallow scrapes in the ground that may be lined with sticks, leaves and other debris. Clutch sizes range from four to six eggs. The eggs are laid over several days and remain dormant until the peahen has finished laying her clutch and commences incubating her eggs. Her body heat ‘strikes’ the eggs and the peachick embryos begin to develop. This ensures that all of the peachicks hatch at the same time regardless of the order in which they were laid. The incubation period is between 28 and 30 days. The chicks leave the nest shortly after hatching and forage for themselves with the peahen pointing at food with her beak. 4.3 Predators In Canberra, the adult peafowl has few natural predators. Their main threats include domestic dogs, cats and European red foxes. Peachicks are particularly vulnerable to predation due to their size and their inability to fly until they are two weeks old which means they cannot roost in trees at night 5. In addition, peahens are not very attentive mothers and many chicks are taken by predators. 6 Birds also fall victim to traffic accidents. 4.4 Environmental impacts Whilst the focus of past public campaigns has been on the negative impacts peafowl have on local residents, peafowl can also have a negative impact on native plant and animal species. They can compete with native birds for habitat, feed on native plants and animals, disturb native vegetation and spread weeds. In the areas where peafowl populations are currently established, environmental impacts are likely to be negligible, however if the population remains unmanaged and is allowed to spread into neighbouring nature reserves then the peafowl could have a significant impact on the environment. In 2013, concerns were raised about the potential for peafowl to colonise the Red Hill Nature Reserve where they could negatively impact on the Yellow Box/Red Gum Grassy Woodland species, including the endangered Button Wrinklewort (Rutidosis leptorrhynchoides). Their foraging can destroy or hinder plant growth leaving bare ground exposed to weed invasion. In addition, they can introduce weed species via their droppings and compete with native fauna for food and roosting sites. To date their distribution has not spread into the reserve and an important aim of the plan is to ensure the peafowl do not colonise the reserve. 4 National Geographic, http://animals.nationalgeographic.com/animals/birds/peacock/ (accessed 13 December 2015) 5 City of Racho Palos Verdes, Peafowl Management Plan (2015) City of Rancho Palos Verdes 6 New Zealand Birds Online http://nzbirdsonline.org.nz/ (accessed 13 December 2015) 4
Draft Feral Peafowl Management Plan 2018 - 2023 4.5 Issues The ACT Government has records of nuisance complaints about peafowl in the Narrabundah and Red Hill area dating back to 2003. A majority of these complaints relate to traffic safety concerns, noise (particularly during the breeding season), droppings and damage to property (i.e. cars and gardens). Residents and management of the St Aidan’s Court Retirement Village, Wylie Street, Narrabundah, have also raised concerns about the potential slip-hazard the droppings posed for elderly residents. The peafowl are free-range and move unrestricted between private and public areas. It should be noted that the nuisance complaints are related to incidents occurring on both private and public land. Peafowl are known to carry a number of infectious diseases and parasites that have the potential to spread, via the birds’ droppings, to livestock and/or humans. These include, fowl pox, haemorrhagic enteritis, avian tuberculosis, fowl typhoid, fowl cholera, coccidiosus, pigeon malaria, salmonella, tapeworms, mites and lice. 7 Transfer to humans can occur through direct contact (hand to mouth) or by drinking rainwater from contaminated roof runoff. The extent to which these diseases are present in the peafowl population of Canberra is unknown. Where peafowl exist in large numbers elsewhere in Australia, such as in Townsville (Stuart Mountain and Magnetic Island) and Kangaroo Island, the management response has focused on their impacts on native plants animals and mitigating their nuisance value. Peafowl have not been declared an environmental pest anywhere in Australia. Whilst the ACT Government has recorded numerous complaints about the peafowl since 2003, feedback from local residents indicates that there is also considerable support for maintaining a peafowl population. Some residents actively encourage their presence through regular feeding. This is consistent with other jurisdictions both in Australia and overseas (e.g. New Zealand 8 and City of Racho Palos Verdes 9), which have also reported a polarisation of public opinion. 4.6 Legislation The Indian peafowl and/or its activities have not been identified as a key threatening process or a pest species under the relevant Commonwealth or ACT Government legislation. The Commonwealth Environment Protection and Biodiversity Conservation Act 1999 provides for the identification and listing of key threatening processes. A threatening process is defined as a key threatening process if it threatens or may threaten the survival, abundance or evolutionary development of a native species or ecological community. For example, the following have been identified as key threatening processes: • predation by feral cats; • predation by European red fox; and • Competition and land degradation by rabbits. 7 Schwartz L.D., 1994 in Landcare Research New Zealand Ltd., Options for controlling peafowl (Pavo Cristatus) in New Zealand (2011) 8 Landcare Research New Zealand Ltd., Options for controlling peafowl (Pavo Cristatus) in New Zealand (2011) 9 City of Racho Palos Verdes, Peafowl Management Plan (2015) City of Rancho Palos Verdes 5
Draft Feral Peafowl Management Plan 2018 - 2023 The ACT’s Pest Plants and Animals Act 2005 provides for the declaration and management of pest species in the ACT. Declared pest animals in the ACT include: • European red foxes; • wild dogs; • wild rabbits; • wild goats; • European wasps; • red imported fire ants; • slider turtle; and • a range of fish. For a full list of current pest animal species visit the ACT legislation website at http://www.legislation.act.gov.au/a/2005-21/di.asp The ACT’s Planning and Development Act 2007 requires the custodian of an area of public land to prepare a plan of management for that land. Public land includes: • reserves – these include wilderness areas, national parks, nature reserves, catchment areas and other prescribed areas of public land; and • public land that is not a reserve including, special purpose reserves, urban open spaces, cemeteries, lakes, sport and recreation reserves and heritage areas. Peafowl populations are currently confined to small areas within the urban environment and Plans of Management for urban areas do not address feral animal management. All animal control actions must comply with the ACT’s Animal Welfare Act 1992. 4.7 Strategic policy The Animal Welfare and Management Strategy 2017-2022 was developed to ensure the ACT Government delivers a consistent and consolidated approach to promoting improved outcomes for animal welfare and management. This Draft Peafowl Management Plan is consistent with the Animal Welfare and Management Strategy and in particular supports action 3.1.5: Develop policies and where necessary revise regulations to manage domestic animals other than companion animals in urban areas. This is a short term action to be delivered within three (3) years. The ACT Pest Animal Management Strategy 2012-2022 (the Strategy) sets the framework and approach for managing the undesirable social, environmental and economic impacts of pest species. The Strategy defines a pest animal as: ‘Any exotic animal causing, or with potential to cause, unacceptable damage to social, environmental or economic assets.’ The management of pest species should be consistent with Figure 1 which outlines the strategic approach to pest animal management. The Strategy includes a risk assessment tool (Appendix A) that is a useful guide to help decide on the priority given to managing a pest animal population. The tool assists in determining the level of risk associated with the pest species, the feasibility of any pest management activities and suggests appropriate actions. 6

Draft Feral Peafowl Management Plan 2018 - 2023 5 Discussion 5.1 Status On 10 August 2015, following a number of complaints from local residents, ACT Government staff visited the area in Narrabundah where the peafowl are known to frequent to determine the current peafowl population in that area. At dusk birds roost in the local trees and a reasonably accurate count was undertaken at this time. The total number of birds observed was 25, which consisted of five adult males and 20 females and juveniles combined. The 20 female and juvenile birds where observed in one tree and four male birds were observed in four separate trees. Another male was heard calling in the distance. This count was confirmed during subsequent staff visits to the area. Observations by ACT Government staff indicated the peafowl population is concentrated in the area bounded by Brockman and Wylie Streets, Narrabundah (Figure 2). There is also a small population of peafowl (approximately eight) in the vicinity of Beltana Road, Pialligo, a majority of which appear to be located at the Willow Park Garden Centre (Figure 2). Peafowl numbers generally increase significantly during the breeding season however, observations over a number of years indicate that the permanent bird population is maintained at around 25-30 birds. Factors such as predation and, to a lesser extent, traffic accidents are likely to play a role in controlling the numbers of peafowl. As peahens nest on the ground, eggs and young chicks that cannot fly are particularly vulnerable to predation by foxes, dogs and cats. The following points need to be considered when determining the appropriate actions and committing resources to address the feral peafowl population issue: • the main negative impacts are social impacts (e.g. noise, defecation, traffic hazards) and damage to private property; • some members of the community support maintaining a peafowl population in Narrabundah; • all peafowl call, but the males are the loudest and their call carries for a long distance. It is usually heard in the early morning and late evening, and almost all day during the breeding season; • complaints received from the community indicate that the negative impacts, which escalate during the breeding season, are localised; • if a small number of peafowl is removed each year and the breeding capacity remains relatively unchanged then the management of feral peafowl will require an ongoing commitment from the ACT Government. • complaints relate to incidents that occur on both public and private land, as such, the management of the peafowl population should be the shared responsibility of both the ACT Government (responsible for public land) and the community (leaseholders of private land); • overall the population has been maintained at around 30 with peak numbers occurring during the breeding season. It is assumed that to date predation by foxes, dogs and cats has kept the permanent population numbers steady; • the peafowl population is confined to two locations as indicated on Figure 2; 8
Draft Feral Peafowl Management Plan 2018 - 2023 • peafowl have not been declared a pest species and have not been identified as a significant environmental risk. Whilst they may compete with native birds for roosting sites and their diet includes small mammals and reptiles, the impact on native species populations in the affected areas is considered minor. • the peafowl can carry transmittable diseases and parasites which can affect both livestock and humans; however, the incidence of disease in the ACT’s peafowl population is unknown and no reports of humans or livestock contracting a disease or parasite from peafowl has been reported; and • cost/benefit analysis - based on previous trapping and relocation programs, the management costs are significant and ongoing, and may outweigh the benefits.

Draft Feral Peafowl Management Plan 2018 - 2023 5.2 Previous control measures 5.2.1 2013 In 2013, following complaints from some Narrabundah residents about the local peafowl population, the ACT Government undertook a trapping and relocation program to reduce, rather than eradicate, the number of peafowl in the area. This decision was made in response to feedback from other local residents who had expressed their desire to keep a peafowl population in the area. A custom-designed trap was commissioned by the ACT Government. The Taronga Zoo agreed to accept up to 20 peacocks but no peahens were able to be re-homed. The trap was set up on private land on the grounds of the St Aidan’s Uniting Church. Following a period of free-feeding, which allowed the birds to become accustomed to the presence of ACT Government staff and the trap, the birds were lured into the trap using food. Fresh corn kernels and bread were favoured by the birds. In total, eight peacocks (males) were trapped (including two that were hand-netted) and re-homed at the zoo. Any peahens (females) trapped as part of the exercise were released back into the local area as these could not be re-homed. Evaluation: The exercise focused on peacocks only. Not all of the peacocks were removed and the number of peahens remained the same. The breeding capacity therefore remained relatively unchanged and the population numbers increased following the breeding season. The relocation program made little difference in the medium-long term. In the future, finding suitable homes for trapped birds will become increasingly difficult as demands are met. The total cost of this exercise was approximately $10,500 which included the costs of trap materials, feed and staff overtime. It did not include work done during work hours (e.g. preparing briefs, delivering letters to residents and meetings). This equates to $1308.68 per bird. Staff wages were also significant as this method is labour intensive. Trapping was undertaken over several days and this was preceded by a period of free-feeding. Staff needed to be present at all times to observe and maintain the trap and monitor the welfare of the birds. The total cost does not take into consideration the loss-of-productivity due to staff being diverted from their regular day-to-day activities. The initial set–up costs were higher in 2013 compared with 2015 due mainly to the cost of the trap. 5.2.2 2015 In 2015, following a number of complaints about peafowl in Narrabundah, in the vicinity of St Aidan’s Court Retirement Village in Wylie and Brockman Streets, the ACT Government undertook another trapping and relocation exercise to reduce the peafowl population in that area. A private zoo agreed to take a number of both male and female birds, however, the cost of trapping, holding and transporting the birds was borne by the ACT Government. 10
Draft Feral Peafowl Management Plan 2018 - 2023 Two trapping options (options A and B) were considered: Option A This option proposed to use an elevated platform to remove the birds from the main roosting tree where up to 20 birds were known to roost (see Section 4.1). It was proposed that staff would use the platform to reach the roosting birds and remove them while they slept, placing each bird in a hessian bag as they were captured. This methodology was based on the assumption that peafowl could be caught and moved easily when they were asleep and that they would remain asleep during the process. This method was untested (see Box 1) and so it was proposed to undertake a trial exercise at another location prior to implementing it at Narrabundah. When this was not possible the decision was made to implement ‘Option B’, the trapping method that was undertaken in 2013 with some success. Box 1: Trialling Option A There have since been unconfirmed reports that rural landowners in NSW used an elevated platform (i.e. cherry-picker) to successfully remove 18 roosting peafowl from a tree in under two hours. This included brief resting periods to allow the birds to resettle when they were roused. If this anecdotal evidence can be substantiated this method would provide a less labour intensive outcome that is also more reliable, cost effective and time-efficient, particularly given that most of the peafowl roost in a single tree and can therefore all be removed within a relatively short timeframe. Trails undertaken on Kangaroo Island also supported this method (see Section 5.4.3). Option B Option B, the trapping method used in 2013, was undertaken by ACT Government staff over several evenings between Tuesday, 11 October and Friday, 30 October, 2015. Free-feeding was undertaken prior to trapping. A total of eight birds, consisting of seven adult females and one juvenile male, were trapped over two nights. After several days the birds appeared to avoid the area. It is likely that they became wary of the trap. As this exercise was undertaken during the breeding season adult peacocks were not targeted due to their long tail trains which made handling them difficult. The trap was located on the grounds of St Aidan’s Church (see Figures 3 and 4) and, as the activities were to be undertaken on private land, permission was required from the leaseholder (the Wesley Uniting Church) before any activity could be undertaken. In addition, letters were delivered to residents in the immediate vicinity advising them the trapping and relocation program was about to commence. 11

Draft Feral Peafowl Management Plan 2018 - 2023 With the relevant permissions in place, the trap was set up and birds were enticed into the trap using food. At the end of each trapping exercise any trapped birds were relocated to a temporary location where they were provided with shelter and food. At the end of the trapping program all trapped birds were successfully relocated to a private zoo near Griffith in New South Wales. Evaluation: The outcomes of this program were similar to those in 2013. However, on this occasion a majority of the trapped birds were female, which reduced the breeding potential of the Narrabundah population. All of the birds were trapped during the first attempt. The costs were less than those incurred in 2013 as the trap that was fabricated for the 2013 program was reused, however this method remained labour intensive and staff wages together with the costs associated with holding and transporting the birds were not insignificant. The total cost, which includes staff overtime, feed and transport, was around $2,500. The total cost does not take into consideration the loss-of-productivity due to staff being diverted from their regular day-to-day activities. There was considerable local community interest in the trapping program with feedback reflecting the polarisation of attitudes amongst residents both in the ACT and elsewhere (see Section 4.5). Some were strongly opposed to the trapping program and supported retaining a peafowl population in the area, whilst others wanted all of them removed and believed more could have been done to address the issues. Residents were also advised that they could contract a private pest controller to remove feral peafowl from private land. The RSPCA was consulted on both occasions (2013 and 2015) to ensure the process met animal welfare requirements. 5.3 Private land verses public land (ACT) During the planning stage of both the 2013 and 2015 trapping and relocation programs, ACT Government staff identified the need for a collaborative response to the feral peafowl population given that their negative impacts occur across both public and private land. Peafowl management should therefore be the shared responsibility of both the ACT Government and the affected residents/lessees. That is, where feral peafowl occur on private land they are the responsibility of the resident/leaseholder and where they occur on public land they are the responsibility of the ACT Government. If the ACT Government proposes to undertake peafowl control measures on private land then no activities should be undertaken without prior consent from the leaseholder. 5.4 Other jurisdictions Feral peafowl populations have also had a negative impact on other areas of Australia, including, Townsville (Magnetic Island and Mount Stuart, Queensland), Rottnest Island (Western Australia) and Kangaroo Island (South Australia). In these areas the relevant authorities have adopted various measures to manage these populations. Rottnest Island, Magnetic Island and Kangaroo Island are fox free. Mount Stuart is outside the normal distribution range of the fox and so sightings of foxes in this area are uncommon. Due to a lack of natural predators to control the peafowl numbers, 13
Draft Feral Peafowl Management Plan 2018 - 2023 the populations of peafowl in these areas have been able to increase significantly over time. The peafowl has not been declared a pest animal in Queensland, Western Australia or South Australia. 5.4.1 Townsville, Mount Stuart and Magnetic Island, Queensland In an effort to contain the feral peafowl population on Mount Stuart and Magnetic Island, the Townsville City Council has put control measures in place to trap and euthanise the birds in accordance with its Townsville Local Government Area Pest Management Plan. The Plan provides the following actions for addressing peafowl: • advise landholders of their rights and obligations in relation to peafowl and assist in the coordinated action by landholders to remove peafowl from properties; • involve RSPCA in any control program of peafowl; and • develop local law provisions to limit maximum numbers of peafowl to be kept, registration of birds, and confinement requirements. In 2014, the council undertook a community education campaign to: • raise awareness of the negative impacts of peafowl on urban areas (i.e. noise, traffic hazards, unpleasant droppings, destruction of landscaping and causing nuisance to outdoor diners) and native wildlife (e.g. competition for habitat); and • deter the invasion of peafowl by discouraging deliberate feeding and advising households not to leave pet food outdoors. Recently, a representative of the Townsville City Council (phone interview, 22 March 2016) confirmed that a number of feral peafowl populations persisted in the Council area, however, peafowl have been eradicated from Magnetic Island. The Council representative stated that the Council does not have an active peafowl trapping program as it is too labour intensive and its focus is on controlling declared pest species. However, the Council does loan pig traps to members of the public who have reported having problems with the birds and want to have them removed from their property. To ensure animal welfare issues are addressed, the Council delivers the trap to the site and examines the suitability of the trap’s location (e.g. the provision of shade, water, shelter). The Council then picks up the trap, including any trapped birds, and the birds are euthanised. Prior to this, trapped birds were being re-homed by the RSPCA but this was not ultimately addressing the issues as the peafowl were likely to become a problem in their new location. The Council recommends using a mirror placed opposite the door of the trap, together with food, to attract peafowl into the trap. 5.4.2 Rottnest Island, Western Australia Peafowl have lived on Rottnest Island since around 1910. Prior to 2009, peafowl populations were removed and relocated to the Perth Zoo. In 2009/2010, the Rottnest Island Authority undertook a cull of feral peafowl as part of an ongoing program to eradicate introduced species on the island. Peahens (females) were removed and euthanised. Following the cull, only three peacocks (males) remained on the island. 14
Draft Feral Peafowl Management Plan 2018 - 2023 The main purpose of the cull was to reduce the negative impact peafowl had on native flora and fauna, and in particular migratory birds. However, it was also undertaken to improve visitor safety and experience. 11 5.4.3 Kangaroo Island, South Australia The report, ‘Management of Feral Peacocks (Pavo cristatus) on Kangaroo Island’, was prepared by Natural Resources Kangaroo Island (the agency) to summarise the outcomes of the 2013/14 management project, provide an analysis of the methods used and make recommendations for future 12. The report identified 18 feral peafowl populations on the island and estimated that the island’s total peafowl population was around 345 (as of May 2014). According to a spokesperson from the agency 13, most of these are located in peri-urban areas where their main food source was from nearby farms. In 2013, the agency embarked on a comprehensive peafowl management project that included a public awareness campaign and an eradication program. At that time there were estimated to be around 380 individuals over 21 populations on the island. The public awareness campaign outlined the negative social, environmental and economic impacts of feral peafowl, which included: • the destruction of gardens; • vehicle collisions; • excessive noise; • defecation on roofs; • spreading weed seeds; • consuming native plants and animals; and • negatively impacting on the poultry industry (peafowl can carry poultry diseases) The campaign also highlighted the individual’s responsibilities under the Natural Resource Management Act 2014 (South Australia). Keeping of domestic peafowl is allowed but they must not be released or allowed to escape. Landholders are not required to control feral populations on their property. The peafowl management project resulted in the removal of around 160 peafowl, 130 of which were from one area, Dover Farm. The report also noted that some sectors of the community supported maintaining a peafowl population on the island and total eradication was unlikely to occur until there was greater community support, which the agency believed could be achieved through further community education. Continued community support is important particularly if access to rural properties is to continue. 11 Science Network WA (website) Rottnest culls feral peacocks http://www.sciencewa.net.au/topics/environment-a-conservation/item/357-rottnest-culls-feral- peacocks (accessed, 2 February 2016) 12 Natural Resources Kangaroo Island (2016) Management of Feral Peacocks (Pavo cristatus) on Kangaroo Island.

Draft Feral Peafowl Management Plan 2018 - 2023 The methods trialled on Kangaroo Island in 2013/14 included: • Locating peafowl populations The method trialled relied on a ‘Judas’ bird to locate feral populations. A semi-domesticated bird (the ‘Judas’ bird) was fitted with a transmitter and released amongst the feral peafowl population. Once the ‘Judas’ bird had successfully integrated into the feral population it was able to be tracked and the feral population could then be located. Peafowl were easier to locate at night when they were roosting. During the day they tended to take refuge in the undergrowth and were more difficult to find. • Night capture This method involved the capture of birds while they roosted in trees at night. In this instance they relied on birds roosting on low branches that were within reaching distance without the use of equipment (e.g. elevated platforms). While this method was labour intensive and opportunistic, the report concluded that capturing peafowl while they were roosting was a successful technique under the right conditions. • The ‘chook house’ trapping method This method was undertaken by landholders and involved observing the birds from a distance as they were lured, using food, into their chook house. Once they were in the chook house the door was shut remotely using a rope. Two residents reported success using this method with one resident catching approximately 80 birds and another catching up to 110. • The ‘pig trap’ method This method is comparable to the ‘chook house’ method. In this trial the ‘chook house’ was replaced with a trap similar to the one used in the ACT in 2013 and 2015 (see figures 3 and 4). The door was held up with a stick attached to a rope. A remote camera was used to observe the peafowl movements, and once the peafowl were in the trap, the door was closed remotely using the rope to remove the stick. The report concluded that this method was labour intensive and required someone on site to observe the birds’ movements. • The alternative ‘pig trap’ method This was similar to above but a light-weight ‘one-way’ door was installed on the pig trap. The peafowl could access the trap by pushing the door open, but once it was in the trap it could not escape. This allowed multiple birds to be trapped without someone being on-site at all times. The trial found that for this method to succeed the door needed to be 100mm above the ground, anymore and the birds could escape and any less and they would not enter. Two birds were successfully captured using this method, however, the remainder of the population then left the area. The report concluded that the trapping activities ‘spooked’ the remaining birds. • Using trained dogs This method proposed the use of trained dogs to flush out the peafowl which are then shot in flight. This method was not trialled. The report concluded that this method had limited uses. 16
Draft Feral Peafowl Management Plan 2018 - 2023 • Shooting The success of this method was dependent on locating the birds. A ‘Judas’ bird was used (see above) to locate feral populations. Shooting was more successful at night and overall 29 peafowl were destroyed using this method (see also Section 6). • Nest destruction Locating the nests presented a challenge and was labour intensive. (See also Section 6) The report concluded that a combination of trapping and shooting, using ‘Judas’ birds to locate feral peafowl populations, were the most effective methods of controlling the island’s feral peafowl (noting that the feral peafowl populations were located in less populated rural and/or semi-rural locations) 6 Management options for the ACT 6.1 Do nothing If no action is taken the negative impacts will not be addressed and they could possibly escalate if peafowl population increases. There is also potential for the birds to increase their range into adjacent suburbs and/or the Red Hill Nature Reserve. 6.2 Community Education/Awareness Community support is important to the success of this Management Plan. Raising community awareness of the impacts peafowl have on the community and the environment can influence the community’s attitude and behaviour. A communications strategy that includes raising public awareness of the issues should be prepared as part of any proposed peafowl population control program. Peafowl can be deterred by removing or reducing food sources and so discouraging people from feeding the birds and warning people against leaving pet food out could assist in reducing the negative impacts of feral peafowl. 6.3 Trap and relocate or euthanise To meet the objectives, trapping should be undertaken annually prior to the breeding season. This should occur until all of the peafowl have been removed. Consideration was given to maintaining a small population of non-breeding peafowl (i.e. males only) to satisfy the sector of the community that liked having a population of peafowl in the area, particularly the colourful males. However, reducing the population and leaving only a small number of peacocks, (as was done on Rottnest Island) will not address the noise issue as the males will continue to call for a mate during the breeding season. The trap design should consider animal welfare issues. For example: • the size of the trap should be large enough for the bird to stretch its wings freely; • the trap should provide sufficient protection from the weather and trapping should not occur during extreme weather conditions; • trapped birds should have access to fresh water; and • trapped birds should not be left in the trap for an extended period of time. Trapping is labour intensive and success varies. 17
Draft Feral Peafowl Management Plan 2018 - 2023 Staff should be experienced in handling peafowl and remain on site during trapping to observe and maintain the trap, and to monitor the welfare of the birds. A staff presence also discourages members of the public from tampering with the trap. Over time peafowl can become trap shy and avoid the area. It is therefore preferable to aim to trap multiple birds in a single attempt rather than individuals. The trap used in the ACT in 2013 and 2015 is capable of accommodating multiple birds. The PestSmart Standard Operation Procedure (SOP); ‘BIR002: Trapping of Pest Birds 14, is a guide to humanely trapping and euthanising pest bird species, including their chicks and eggs, and can equally be applied to peafowl 15. The SOP recommends captured birds are euthanised rather than relocated as relocation is not an acceptable option on welfare grounds. This is based on advice from the National Consultative Committee on Animal Welfare. It is advisable to undertake trapping outside of the breeding season to ensure that there are no abandoned eggs or chicks. If trapping must occur during the breeding season then every effort should be made to locate and humanely destroy the eggs and chicks (see below). Furthermore, outside of the breeding season the peacocks do not have their train of tail coverts so they are easier to handle. The highly publicised trapping and relocation programs undertaken in 2013 and 2015 attracted a number of enquiries from members of the public offering to re-home birds on private rural properties. To date such requests have been denied on the basis that relocating the birds could result in a feral population establishing at another location. Relocating peafowl is not a long term solution as there are limited suitable re-homing options available and these will become more limited over time as demands for the birds are met. Also, there is generally more demand for the males due to their attractive train and so re-homing peahens can present a challenge. To date the option of euthanising the trapped birds has not been considered due to the potential for negative community feedback. However, this option needs to be considered in the future given the limited opportunities for rehousing. The ACT Government has trained staff who can undertake the trapping on public land however, on private land leaseholders should be advised to undertake to work themselves or contact a private licensed pest animal controller to undertake the work on their behalf. All work undertaken must be in accordance with animal welfare legislation. Treating the abandoned chicks and eggs As previously discussed, it is strongly advised trapping is undertaken outside of the breeding season to avoid the possibility of abandoned eggs and chicks. If this is not possible however, abandoned chicks or eggs should be located as soon as possible and humanely destroyed. This should be done by a suitably qualified person and in 14 Invasive Animals CRC (2012) Pestsmart Standard Operating Procedure BIR:002: Trapping of pest birds, Invasive Animals CRC and Australian Government. 15 Note: The SOP does not override relevant legislation and should only be used subject to the applicable legal requirements (including WH&S) operating in the ACT. 18
Draft Feral Peafowl Management Plan 2018 - 2023 accordance with animal welfare legislation. The Pestsmart SOP provides advice on euthanasia of chicks and the destruction of eggs (see also section 6.3). Any peafowl eggs over 14 days old (greater than half way to the hatching) are considered to have developed sufficiently to allow perception of pain. However, it can be difficult to determine the age of the eggs. The Pestsmart SOP therefore recommends destroying the eggs by freezing them to
Draft Feral Peafowl Management Plan 2018 - 2023 In their research paper on options for controlling peafowl, David and Latham (2011) outlined the following issues related to using poison to manage peafowl populations: • due to the size of the peafowl, a significant amount of poison would need to be ingested; • if a sub-lethal doses are ingested this may result in the bird acting abnormally and deterring other peafowl; and • Peafowl may fly off after ingesting the poison and die elsewhere which can be upsetting to some members of the public. 6.6 Fertility control David and Latham (2011) discussed the use of Ovocontrol-G® (a bait containing nicarbazin) to control fertility in peafowl populations. Ovocontrol-G® is a daily treatment that is administered through regular feeding. It was developed in the United States as a fertility control agent for pigeons, geese and ducks and has not been trialled on peafowl. Ovocontrol-G® is currently not registered for use in Australia and it would need to be assessed and approved before it could be used. David and Latham (2011) have also stated that the initial costs of fertility control using Ovocontrol-G® would be high. 6.7 Deterrents There are a number of deterrents available on the market to discourage birds, none of which have been specifically designed to deter peafowl. Devices include ‘scare windmills’, ‘flying eagle kites’ and laser emitters. David and Latham (2011) stated that whilst these devices have not been tested on peafowl they are unlikely to be a viable long-term option as peafowl will become accustomed to them over time. There are also devices that emit sounds, for example propane gas cannons, but these types of devices are more suited to a rural environment where there is less potential for noise disturbance. 6.8 Bird exclusion methods Exclusion methods include installing electric wires and monofilament lines to prevent nuisance birds from nesting or roosting in urban areas. These methods are unlikely to be effective in discouraging peafowl as they will relocate to another nesting or roosting site within their range. 7 Future management of feral peafowl in the ACT Table 1 outlines the various options for managing ACT’s feral peafowl population and the pros and cons of each. It also identifies the options adopted by the ACT Government. The ACT Government is responsible for feral peafowl on public land. Based on the analysis of the various controlled methods (see Section 6), the preferred option is to trap and relocate peafowl. However, if relocation is not possible because suitable homes cannot be found, birds will be trapped and euthanised. Breeding season should be avoided, but if trapping occurs during the breeding season every effort should be made to locate and humanely euthanise abandoned chicks and eggs. The option of trapping the birds using an elevated platform (i.e. cherry-picker) should also be investigated (see Box 1). 20
Draft Feral Peafowl Management Plan 2018 - 2023 The community plays an important role in addressing the feral peafowl population in the ACT and community awareness and engagement are an integral part of any management program. Generally, residents/lessees will be responsible for addressing feral peafowl management issues on private land. However, the ACT Government may consider lending traps to members of the public.
