GENUS HALIJEETUS. 



352. Haliseetus leucocephalus (Linn.). BALD EAGLE. 



Tarsus feathered only half way down, middle and outer toes without 

 web ; wing 1 pointed, secondaries much shorter 

 than primaries ; tail less than two thirds as 

 long' as wing', rounded. Adults. Head, 

 neck, tail, and tail coverts snowy white ; rest 

 of plumage blackish or dark brownish, 

 feathers edged with brown. Young : first 

 year wholly black except for white bases of 

 feathers showing' through ; second or third

 mixed gray, brown, black, and white. Male : 

 length 30-35, extent about 7 feet, wing 

 20.00-25.90, tail 11.00-15.20, bill 1.85-2.25.

 wing 23.50-28.00, tail 12.50-10.00, bill l.'JO- 

 2.35. 



Distribution. Mainly in the United States 

 and Mexico. Breeds in suitable localities 

 throughout its range. 



Nest. A bulky mass of sticks, sea- 

 weed, rushes, turf, vines, or plant stalks, 

 on cliffs or in tall trees. Eggs : usually 2, 

 white. 



Food. -- Mainly fish, but also squirrels, rabbits, prairie dogs, lambs, 

 carrion, and waterfowl. 



The bald eagle was unfortunately selected as our national emblem 

 instead of the nobler golden eagle, as it is at times both a scavenger 

 and a robber. It lives largely on fish, diving for them and taking 

 them itself, stealing them from a fish hawk, or, in company with 

 ravens and vultures, feeding on dead fish cast up by the waves along 

 river banks. 



It must be acknowledged, however, that the eagles show great 

 skill in their piratical exploits and courage in defense of their nests, 

 and that they have a noble, commanding bearing which is not alto- 

 gether belied by their daily deeds. 



GENUS FALCO.

 projection separated by notch from hooked tip ; nostril small, circular,
