ADALBERT'S IMPERIAL EAGLE. 77 
three inches and six tenths; tarsus four inches and two tenths; middle 
toe two inches and three tenths; claws one inch and five tenths; upper 
mandible three inches; depth of beak at base one inch and two 
tenths. Plumage. — Top of the head dark brown; nape and sides of 
head and back of neck have the feathers lanceolate, and of a yellowish 
cream-colour, the shafts black, and mottled less above than below 
with brown; scapularies, back, wings, upper tail coverts, end of tail, 
throat, anterior neck, and all the lower parts a rich deep chocolate 
brown, darker on the lesser wing coverts and the primaries, almost quite 
black. On the back and greater wing coverts the brown is of two 
shades, mingled on the rump and upper tail coverts with white. The 
shoulders and edge of the wing from the junction with the back to 
the carpal joint white, mixed with single feathers of chocolate brown, 
giving the white marks a banded appearance. On the shoulders the 
white is very pure, but at the carpal joint it begins to assume the 
yellowish cream-colour of the back of the neck. Tail, upper two thirds 
grey, with bands, more or less irregular and deep in colour, of brown, 
lower third dark chocolate brown, with a light fringe to the tips; 
under tail coverts, brown; wing lining — above dark brown with a few 
white feathers, below lighter hair brown. The shafts of the primaries 
beneath are beautifully crossed with black and white. 
Adalbert's Imperial Eagle is entirely confined to Spain. Its habits 
and nidification are precisely the same as those of its congener. 
The egg is from a very beautiful specimen brought from Spain by 
my friend Mr. Savile G. Reid.
