Eagle in : Raptor grade, not one genus
[174] [more-eagle-74] In , the field log for Eagle is headed “Raptor grade, not one genus.” The figure kept beside that heading is 3. It is a count or a date from the work, not a rank of the species’ worth. A zoo birthday card does not replace the log. Australia, New Zealand, and southern African English programmes add ice, island and savanna files the North Atlantic does not hold.
Level cruising for large eagles is often 50–80 km/h. A hunting stoop is a different regime — trained golden eagles have been filmed above 240 km/h. Did DDT almost erase North American bald eagles? 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.
Keep , “Raptor grade, not one genus,” and 3 together or the note on Eagle stops being that year’s record.3
