This guide has very good drawings of birds of prey. All the links lead to more information on .Ī Field Guide to Hawks of North America (Peterson Field Guides)Ī general field guide using field marks and flight silhouettes is William S. Owls, being night fliers are not included.
The books all focus on day-flying raptors. Here is a list of some of the best books on identifying birds of prey. There is much to learn on identifying birds of prey. I think the behavioral approach used along with the field marks approach, helps to make a very knowledgeable birder. I have gotten pretty good at telling a Turkey Vulture from any other bird. And a Turkey Vulture often looks huge, where a Red-tailed Hawk can look smaller. A soaring Turkey Vulture’s silhouette takes on a more pronounced V-shaped than a Red-tailed Hawk. The Turkey Vulture is a dark underneath with a dark body, dark V-shape on the wings and translucent white “fingers” at the end of its wings. I focused on identifying a Turkey Vulture. I often check the manner of flight, color pattern of feather and body and whether other birds are in the sky with it. When they are tiny specks in the sky is not easy to distinct between the two birds. I often see Red-tailed Hawks and Turkey Vultures flying overhead. If you learn these profiles and behavior you will be able to identify raptors even when they are circling miles above you. Even still, it is hard to be accurate all the time.īirds of prey species often have distinctive ways of flying and holding their wings. the bird’s overall shape, size and color and silhouetteĪll of these behaviors and clues add up to a good identification.does it fly with soaring, rocking motions or long flights or short bursts.the rhythm of the flaps and glides while flying.This behavior approach looks at a number of factors. Instead of looking for plumage details or eye color, more emphasis is placed on how a bird behaves. This is where the behavioral approach comes in handy. This works best when you have a clear and close look at an animal.īut, if the birds is flying a mile overhead, then the field mark system doesn’t work as well. This is called the ‘field mark’ approach. His field guides focused on color, plumage, marking and other easily seen details. The field mark system was pioneered in book form by Roger Tory Peterson.
They used both known field marks and behavior to identify an animal. Our ancestors who stayed close to the land and its rhythms could tell species apart at long distances. The old ‘field mark’ system has been supplemented with a more behavioral approach. British Birds Of Prey Identification Guidesįind out more about some of the most common British birds of prey including identifying features, nesting and feeding habits and take a listen to their calls.Identifying birds of prey has undergone a transformation. Birds of prey can be difficult to tell apart, particularly when you can only catch a fleeting glimpse of them or see a distant silhouette in the sky. Sparrowhaks will sometimes visit gardens, and peregrine falcons can be spotted in towns and cities, whereas it is more difficult to see owls who rarely conduct their activities during the day. British birds of prey tend to feed on small mammals, reptiles, insects, fish, birds and molluscs while Old and New world vultures prefer to eat carrion. Most birds of prey are diurnal meaning they hunt during the day although some owls are nocturnal and hunt solely after dark. They also have acute vision and hearing and powerful talons and beaks.īirds of prey can be divided into a number of families including buzzards and hawks, falcons, vultures, kites, harriers, eagles, owls and osprey, and in the UK you can find examples from all of these groups except for vultures. Birds of prey, otherwise known as raptors, by definition catch their food using their feet instead of their mouths like most other birds.
