Eagle in 1972: DDT reversal

By 1963 the lower-48 count was about 417 nesting pairs. The 1972 DDT ban plus Endangered Species Act protection preceded the 2007 delisting. No. “Eagle” is a grade inside Accipitridae. Sea eagles (Haliaeetus) and booted eagles (Aquila) split tens of millions of years ago. Why is the Philippine eagle a different conservation story?

Pithecophaga jefferyi is a forest-interior endemic with perhaps a few hundred adults. Logging and shooting, not eggshell thinning, dominate the threat list. Many pairs are socially monogamous and reuse eyries, but extra-pair behaviour and mate replacement after nest failure are documented.

What do white-tailed eagles eat in the UK reintroduction? Fish, seabirds and carrion dominate. Isle of Mull and Isle of Wight releases (from 1975 and 2019 programmes) track sheep-loss complaints against actual diet data. Breeding spans Alaska to northern Mexico and both coasts of Canada. The US recovery is the famous chapter, not the whole range.
