Red-tailed hawk : From Wikipedia: The Red-tailed Hawk (Buteo jamaicensis) is a medium-sized bird of prey, one of three species colloquially known in the United States as the "chickenhawk." It breeds almost throughout North America from western Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the largest members of the genus Buteo in North America, weighing from 1.5 to 4.4 pounds and measuring 18 to 26 inches in length, with a wingspan from 43 to 57 inches. The Red-tailed Hawk displays sexual dimorphism in size, as females are 25% larger than males. Red-tailed Hawk plumage can be variable, depending on the subspecies. These color variations are called morphs, and a Red-tailed Hawk may be light, dark, or rufous. The Red-tailed Hawk is successful in large part because it tolerates a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, tropical rainforests, agricultural fields and urban areas. It is legally protected in Canada, Mexico and the U.S. by the Migratory Bird Treaty Act of 1918. It is carnivorous, and an opportunistic feeder. Its diet is mainly composed of small mammals, but it also includes birds and reptiles. The Red-tailed Hawk is a popular bird in falconry. Approximately 60% of all raptors under 1 year of age taken from the wild for use in American falconry are Red-tailed Hawks. The Red-tailed Hawk also has significance in Native American culture. Its feathers are considered sacred by some tribes, and are used in religious ceremonies.

Gyr Falcon : From Wikipedia: The Gyrfalcon (Falco rusticolus), also spelled Gyr Falcon, sometimes Gerfalcon, is the largest of all falcon species. The Gyrfalcon breeds on Arctic coasts and islands of North America, Europe and Asia. The "g" is pronounced like the "j" in "jar". The Gyrfalcon is a bird of tundra and mountains, with cliffs or a few patches of trees. It feeds only on birds and mammals. Like other hierofalcons, it usually hunts in a horizontal pursuit, rather than the Peregrine's speedy stoop from a height. Most prey is killed on the ground, whether they are captured there or, if the victim is a flying bird, forced to the ground. The diet is to some extent opportunistic, but a majority of breeding birds mostly rely on Lagopus grouse. Avian prey can range in size from redpolls to geese and can include gulls, corvids, smaller passerines, waders and other raptors (up to the size of Buteos). Mammalian prey can range in size from shrews to marmots (sometimes 3 times heavier than the assaulting falcon), and often includes include lemmings, voles, ground squirrels and hares. They only rarely eat carrion. The Gyrfalcon is Iceland's staðfugl (national bird), as well as the official bird of Canada's Northwest Territories. In medieval times, the Gyrfalcon was considered the king's bird. Due to its rarity and the difficulties involved in obtaining it, in falconry the gyrfalcon was generally reserved for kings and nobles.

Saw-whet Owl : From Wikipedia: The Saw-whet Owl (Aegolius acadicus) is a small owl. Adults are 18cm long with a 43 cm wingspan. They have a large round light grey face with brown streaks, a dark bill and yellow eyes. The underparts are pale with dark streaks; the upper parts are brown with white spots. Their breeding habitat is coniferous forests, sometimes mixed or deciduous woods, across North America. They nest in a tree cavity, usually one created by a woodpecker. They will sometimes use nesting boxes. Some are permanent residents; others may migrate south in winter or move down from higher elevations. These birds wait on a low perch at night and swoop down on prey. They mainly eat small rodents; on the Pacific coast, they may also eat crustaceans and aquatic insects. Like many owls, these birds have excellent hearing and exceptional vision in low light. This bird was named for its call, which is said to resemble a saw being sharpened with a whetstone. It is fairly common, but not always easy to spot.

Long-eared Owl : From Wikipedia: The Long-eared Owl (Asio otus) is a species of owl which breeds in Europe, Asia, and North America. This species is a part of the larger grouping of owls known as typical owls, family Strigidae, which contains most species of owl. The other grouping of owls are the barn owls, family Tytonidae. The Long-eared Owl is a medium sized owl, 31-37 cm in length with an 86-98 cm wingspan. It has erect blackish ear-tufts, which are positioned in the center of the head. The female is larger in size and darker in colouration than the male. The Long-eared Owl’s brownish feathers are vertically streaked. Tarsus and toes are entirely feathered. Eye disks are also characteristic in this species. However, the eye disks of A. otus are darker in color or rusty-orange. This nocturnal species is perhaps most easily seen perched in a tree in its daytime roost. The Long-eared Owl's breeding season is from February to July. This bird is partially migratory, moving south in winter from the northern parts of its temperate range. Its habitat is forest close to open country. It nests in trees, often coniferous, using the old stick nests of other birds such as crows, ravens and magpies and various hawks. The average clutch size is 4-6 eggs, and the incubation time averages from 25-30 days. It will readily use artificial nesting baskets. An unusual characteristic of this species is its communal nesting in thickets during the winter months. The Long-eared Owl hunts over open country by night. It is very long winged, like the similar Short-eared Owl, and glides slowly on stiff wings when hunting. Its food is mainly rodents, small mammals, and birds.

Saker Falcon : From Wikipedia: The Saker Falcon (Falco cherrug) is a very large falcon. This species breeds from eastern Europe eastwards across Asia to Manchuria. It is mainly migratory except in the southernmost parts of its range, wintering in Ethiopia, the Arabian peninsula, northern India and western China. The Saker Falcon is a large hierofalcon, larger than the Lanner Falcon and almost as large as Gyrfalcon at 47-55cm length with a wingspan of 105-129cm. Its broad blunt wings give it a silhouette similar to Gyrfalcon, but its plumage is more similar to a Lanner Falcon's. Saker Falcons have brown upperbellies and contrasting grey flight feathers. The head and underparts are paler brown, with streaking from the breast down. Males (called sakrets in falconry) and females are similar, as are young birds, although these tend to be a duller brown. The call is a sharp kiy-ee. The Saker Falcon is a bird of open grassland with some trees. It is a carnivore, usually hunting by horizontal pursuit, rather than the Peregrine's stoop from a height, and feeds mainly on rodents and more rarely birds. This species usually builds no nest of its own, but lays its 3-6 eggs on the ground or in an old stick nest in a tree which was previously used by other large birds such as crows, ravens or buzzards. However, it is known to have occasionally laid eggs in nests built on cliffs.

Great Horned Owl : From Wikipedia: The Great Horned Owl, Bubo virginianus, is a large owl native to North and South America. It is an adaptable bird with a vast range, though it is not as widespread as the Barn Owl. They can take up residence in trees that include deciduous, coniferous, and mixed forests, tropical rainforests, pampas, prairie, mountainous areas, deserts, subarctic tundra, rocky coasts, mangrove swamps, and some urban areas. Though less common in the more extreme areas (i.e. the heart of the deserts, extremely dense rainforests) and missing from the high Arctic tundra, they are found in most habitats. Individuals range in length from 18 to 27 inches and have a wingspan of 40 to 60.5 inches. An average Great Horned Owl is 22 inches long, has a wingspan of 49 inches and weighs about 3.1 lbs. Generally, the largest owls are found closer to the Polar regions and the smallest owls are found closer to the Equator. Females are larger than males. Adults have large ear tufts, a reddish, brown or gray face and a white patch on the throat. The iris is yellow, except in the race B. v. nacurutu where it is amber. The ear tufts are not actually ears, but simply tufts of feathers. The underparts are light with brown barring; the upper parts are mottled brown. The legs and feet are covered in feathers up to the talons. Owls also have spectacular binocular vision needed to pinpoint prey and see in the dark. Owls cannot move their eyes like we can. They are locked in a special circular bone. Therefore, their neck must be able to turn a full 270 degrees in order to see in other directions without moving its entire body. An owl's hearing is as good — if not better — than its vision. Owls have stereo hearing that allows them to find the exact location of their prey. These birds also have 500 pounds per square inch of crushing power in their talons. A normal man has about 60.

Barred Owl : From Wikipedia: The Barred Owl, Strix varia, is a large typical owl. It goes by many other names, including eight hooter, rain owl, wood owl, and striped owl, but is probably known best as the hoot owl. Its breeding habitat is dense woods across Canada, the eastern United States and south to Central America; in recent years it has spread to the western United States. The Barred Owl's nest is often in a tree cavity; it may also take over an old nesting site used by a crow or squirrel. It is a permanent resident, but may wander after the nesting season. The adult is 44 cm long with a 112 cm wingspan. It has a pale face with dark rings around the eyes, a yellow beak and brown eyes. It is the only typical owl of the eastern United States which has brown eyes; all others have yellow eyes. The head is round and lacks ear tufts, a distinction from the Short-eared Owl. The upper parts are mottled gray-brown. The underparts are light with markings; the chest is barred horizontally while the belly is streaked lengthwise. The legs and feet are covered in feathers up to the talons.

Eastern Screetch Owl - Red Phase : From Wikipedia: The Eastern Screech Owl (Megascops asio) is a small owl. Adults have either rusty or dark grey intricately patterned plumage with streaking on the underparts. Small and stocky, short-tailed and broad-winged, they have a large round head with ear tufts, yellow eyes and a yellowish bill. Rusty birds are more common in the southern parts of the range; pairings of the two colour variants do occur. A pale grey variation also exists in western Canada and the north-central United States. The color variations are referred to as "red-phase" and "grey-phase" by bird watchers and ornithologists. Their breeding habitat is deciduous or mixed woods in eastern North America. Usually solitary, they nest in a tree cavity, either natural or excavated by a woodpecker; they will also use nesting boxes. They are strictly nocturnal, roosting during the day in cavities or next to tree trunks. These birds wait on a perch on low limbs in open woods and along forest edges and swoop down on prey; they may also catch insects in flight. They mainly eat large insects and small rodents, as well as small birds. They are active at night or near dusk, using their excellent hearing and night vision to locate prey.

Hybrid Falcon : From Wikipedia: Adult falcons have thin tapered wings, which enable them to fly at high speed and to change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers which makes their configuration more like that of a general-purpose bird such as a broadwing. This is to make it easier for them to fly while learning the exceptional skills required to be effective hunters in their adult configuration. A falcon's wings are shaped like a scythe.
