Sp. CH. Form, very robust. Size large. Sternum, stout, with the top of the keel rounded. Tongue, long, fleshy, 

 grinned f,r it- entire length, liorny at tip, where it is rounded but not bifid. Bill, strong and well-curved. Tarsus feftth- 

 ered in front for half its length. Sexes, similar in color.

fiffllinija. Are at first covered with a whitish down which becomes darker as the birds grow older, then they gradu- 

 umc the plumage, last described. lu the last three stages, the iris and bill are brown, the feet are yellow, and the 



cere is irrccuish. 



OBSERVATIONS. 



Specimens of the same nge and sex exhibit but little variation in plumage. Readily known when adult by the white 

 head and tail, and in all stages liy, the partly feathered tarsus. Florida birds are smaller than those from further north. 

 Distributed as a constant resident throughout North America.

DESCRIPTION OF NESTS AND EGGS. 



Nests, usually placed in trees or occasionally on rocky cliffs; they are very bulky structures, composed of sticks, ar- 

 ranged in a compact manner. 



-. usually two in numlier, varying from spherical to oval in form, ashy or dirty-white in color, unspotted. Dimen- 

 f'rom 2-75x3-00 to2'82x2'85. 



HABITS. 



Although the White-headed Eagles constantly occur in the wilder portions of New 

 England, they are rare in the vicinity of Boston; thus I do not remember of having seen 

 more than three or four, within the past fifteen years, at Newton, and the last one that I 

 observed \\as a fine adult which flew slowly by a few days ago, early in February, 1880. 

 I have little doubt but that these fine birds breed even in Massachusetts but such instances 

 are very rare and in order to study this species to perfection, one must visit Florida, where 

 there are more nests in a given area than in any other section, and I have several times 

 found three or four eyries, all occupied, within the radius of a mile. 



These birds begin to breed in Florida very early in January, and the nest is usually 

 placed in a huge pine, many feet from the ground. The first nest that I found was at 

 Lake llarney, during my earliest visit to the state and as I was desirous of seeing what it 

 contained, I determined to cut down the tree, for all my efforts to climb the huge bole,
