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 white-tailed hawk is a large, stocky hawk. It is close in size to the Swainson's (Buteo swainsoni) and red-tailed hawks (Buteo jamaicensis), its mean measurements falling slightly ahead of the first, and slightly behind the latter. It can attain a total length of 44–60 cm (17–24 in) and a wingspan of 118–143 cm (46–56 in).

The default color of vertebrate eggs is the white of the calcium carbonate from which the shells are made, but some birds, mainly passerines, produce colored eggs. The pigments biliverdin and its zinc chelate give a green or blue ground color, and protoporphyrin produces reds and browns as a ground color or as spotting.
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.
