They have appeared in the courts of kings, Tourism Secretariat and A Rocha donors. Special on the arms of falconers and have been studied thanks goes to the following people who by many biologists and scientists.

Many thanks to Valorie raptors are now recognized as important links in Goossen, Rudolph Koes, Allen Schritt, Bob sustaining the ecosystem. Legislation protects all Shettler and Peter Taylor for their review of the raptors in North America and for some species guide.

Cover spring. For the novice birdwatcher, identifying photo by A. Aug. Cover background image by birds of prey can be a major challenge and the Raymond Klassen. cause of much frustration. Even experts can have difficulty with raptor identification. Many raptors look very similar to each other because of their mottled and dull plumages. Adding to the challenge of identification are the differing plumages among juveniles, subadults as well as adults. Also, some species have different colour morphs. Recommended citation: Goossen, J.

ABOUT RAPTORS HOW TO USE THIS GUIDE The term raptor applies to birds of prey including This field guide is intended to be a helpful hawks, falcons, eagles and owls. Raptors are birds introduction to the novice birdwatcher and a which capture and consume other living creatures quick reference guide for the expert in the or feed on dead animals (carrion). Generally the identification of raptors in the PVR (see map on term raptor applies to birds of prey which are back cover). The guide focuses on the active during the day (diurnal) thereby excluding identification of raptors in flight. owls which are mostly active at night (nocturnal). Of the 21 diurnal raptor species recorded in So how do you use this guide? First determine Manitoba, only 16 breed in the province. that the bird you are viewing is a raptor. Then consult the silhouette guide on the front inside Diurnal raptors can be grouped into seven cover to decide what type of raptor you are categories: vultures, osprey, eagles, harriers, looking at. Is it a vulture, osprey, eagle, harrier, accipiters, buteos and falcons. Vultures are accipiter, buteo or falcon? Once you have soaring birds which feed primarily on carrion and decided what type of raptor you are observing, rely on their sense of smell and good eyesight to consult the section in the guide that pertains to find food. Ospreys are the fish hawks of the raptor that group of raptors. For those unfamiliar with world. Eagles are large birds known for their the topographical terminology of birds, please strong flight and powerful strength. Harriers are check the glossary section of this guide for often seen flying low over marshes or grasslands definitions and see Figure 1 which illustrates in search of small rodents. Accipiters are agile and many of the terms. swift woodland hawks that pursue songbirds. Buteos are the chunky hawks seen soaring over fields and open woodlands or perched on telephone or hydro poles. Falcons are the fast, powerful aerial hunters of the raptor world. In the Pembina Valley Region (PVR), raptors live in or near a variety of habitats including forests, Rough-legged Hawk riparian woodlands, marshes, lakes and grasslands. Photo by V. Berardi 5 6

THE PEMBINA VALLEY REGION The Pembina Valley Region harbours a rich diversity of flora and fauna. Although agriculture is predominant in the region, wildlife habitats can be found in woodlots and wetlands, along streams and rivers and in grasslands. Within this region, the Pembina Valley is a significant riparian corridor and an important migratory thoroughfare for thousands of birds including raptors. The Pembina River, with its source in the Turtle Mountains, flows through this region into the United States where it empties into the Red River near Pembina, North Dakota. Slopes of the Pembina Valley are typically covered by deciduous forest and shrubs.
