Like most Buteo hawks, red-tailed hawks do not primarily hunt birds in most areas, but can take them fairly often whenever they opportune upon some that are vulnerable. Birds are, by far, the most diverse class in the red-tailed hawk's prey spectrum, with well over 200 species known in their foods.
The osprey (/ ˈ ɒ s p r i,-p r eɪ /; [2] Pandion haliaetus), historically known as sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish ...
Various species of sea turtles bury their eggs on beaches under a layer of sand that provides both protection from predators and a constant temperature for the nest. Snakes may lay eggs in communal burrows, where a large number of adults combine to keep the eggs warm. Some species coil their torsos around the eggs to provide heat for incubation.
Some birds stay at colonies throughout the year but most birds fly to colonies in August to woo and sweep burrows for breeding. After mating, females leave colonies for one to six weeks for forming eggs. Males also leave but return to nest sites a few times. Eggs are laid from early September and to mid-October.
Parents feed young hawks from early in their lives until they leave the nest. [23] Young hawks, while still in the fledgling phase, will leave their nests as early as six weeks old, but they do not hunt until they are older. Like most birds of prey, hawks kill their prey with their talons. Hawks usually prefer hunting just before nightfall when ...
The red-shouldered hawk (Buteo lineatus) is a medium-sized buteo. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico.
The chemicals accumulated in the bodies of grain-eating birds and had two effects on top predators like the Eurasian sparrowhawk and peregrine falcon: the shells of eggs they laid were too thin, causing them to break during incubation; [35] and birds were poisoned by lethal concentrations of the insecticides.

These hawks may readily take to conifers to roost, generally sleeping with their heads tucked in. [2] [104] During daylight hours, they tend to preen while sitting on a perch about 11 times a day, and may take about 1–20 minutes to do so. [56] When attaining water to drink, Cooper's hawks appear to prefer to come to relatively secluded ...
