Buteo antillarum Clark, Proc. biol. soc. Washington, vol. 18, p. 62, Feb. 21, 
1905. 
Type locality .— Chateaubelair, St. Vincent. 
Color .— Above brown, the feathers white at the base and mar¬ 
gined with rufous to the tips, the white bases showing through on 
the nape, and giving that region a mottled appearance. Wing 
coverts margined all around with rufous. Lores whitish ; head all 
around brown, the feathers margined with rufous, being darkest at 
base of bill and under eyes. Throat light buff, streaked with black¬ 
ish brown. Breast rufous brown, mottled with light buff, more 
heavily toward abdomen, which is mainly light buff barred with 
rufous brown. Under tail coverts light buff. Thighs buff, barred 
with many transverse lines of rufous. Under wing coverts buff like 
the thighs, many of the feathers having small black central streaks. 
Upper tail coverts tipped with white. Tail brown, tipped with 
light grayish brown, with white at the extremity, crossed by two 
bands and an indicated third band of light grayish brown, becoming 
white on the inner webs of the feathers. 
Iris yellowish white 1 ; cere yellow; feet orange yellow; bill dark 
slaty. 
This species differs from B. platypterus, to which it is most 
closely allied, in being smaller and much more rufous ; the rufous 
edgings to the feathers above wider, the underparts more rufous, 
and the thighs buff, more thickly barred than in that bird. In the 
young the ground color below is buffy white, becoming darker on 
the abdomen and thighs. The iris is yellowish white in all stages. 
A comparison of the specimens from St. Vincent with eight 
others from Dominica, shows that the Dominica bird is darker and 
more sooty above, more heavily marked on the breast, and deeper 
'The iris of B. 'platypterus is brown ; but Dr. Glover M. Allen tells me that 
he once obtained an immature bird of that species at Intervale, New Hamp¬ 
shire, which had yellow irides.
