Eagle
Bald Eagle (Haliaeetus leucocephalus)

In the United States, breeds best in the swamps of the Everglades. On a test diet of mice, must eat 68.3 grams per kg of body weight daily for maintenance. Sexual dimorphism is exhibited by male usually weighing a third less than the female. Hotter than most mammals (average body temperature 107o), with diurnal cycles. While bumblefoot is common in this species, it is preventable. Tallow baits used for magpie or raven control are danger to these carrion feeders. Regurgitation of pellets of indigestible matter is normal in the course of nutritional habit. Photoperiodic breeding cycle can be activated artificially, but imprinting is a concern. Young have bristle-like feathers on each side of the beak, and weak specimens that fail to respond to visual feeding temptations have been made to bite at small pieces of meat by rubbing gently across the tips of the bristles. (Note: the eagle came in second, after the turkey, as Ben Franklin's nomination for the National bird of the United States.)
