Cooper’s Hawks look rather slim and straight backed when perched, unlike the hunchbacked and short-tailed look of Red-shouldered Hawks. Juveniles have thinner streaks on the breast than juvenile Red-shouldered Hawks.

The species, named for its feathered legs, breeds throughout the arctic and sub-arctic regions of North America, Europe, and Asia. In North America, roughlegs typically breed in the open tundra and semi-open taiga of Alaska and Canada.

Raptors who prey on rough-legged hawks of most ages at varied times of year may include numerous eagles (especially the golden eagle (Aquila chrysaetos), though also sometimes other Aquila in Eurasia and seldomly Haliaeetus eagles) as well as large falcons.

It is omnivorous, feeding on small mammals, such as mice, voles, lemmings, squirrels, and sometimes small birds.

The name “Rough-legged” Hawk refers to the feathered legs. The Rough-legged Hawk’s cliffside nest, a bulky mass of sticks, sometimes contains caribou bones. Nesting pairs need a lot of space: usually only a single pair will nest on a quarter-mile-long cliff.

The common nightingale is slightly larger than the European robin, at 15–16.5 cm (5.9–6.5 in) length. It is plain brown above except for the reddish tail. It is buff to white below. The sexes are similar.

Larks. Most larks are pale brown with dark streaks in subtly different patterns. They have rounded wings and rather short tails, stout legs with a long, straight hind claw and strong, triangular, pointed bills. Most species sing while in flight in open areas with few high perches.

While bald eagles are much larger than than owls, the owls are “the tigers of the air,” Anderson says. Bald eagles have an average wingspan of 83 inches and weigh 10 pounds; great horned owls have about half the wingspan, at 48 inches, and weigh just 3.7 pounds.
