656 REPORT OF THE HARVARD AFRICAN EXPEDITION 
feet of a large raptore secured in eastern Liberia by Pye-Smith. This eagle is 
well known to haunt heavy forest, building its nest in high and almost inacces- 
sible trees; it feeds particularly on monkeys, and in this specialization of habit 
forms an interesting parallel to the American Harpy Eagle that preys on sloths. 
Kaupifalco monogrammicus monogrammicus (Temminck). Northern Lizard-buzzard 
Falco monogrammicus Temminck, Planches Color., livr. 53, pl. 314, 1824; Senegal. 
Small, length about 14 inches; above gray, lores and a spot below the eye white; throat white 
with dark central streak; throat pale gray; belly and feathers of the legs banded white and blackish 
eray; tail dark, its terminal third or fourth banded with white; wing feathers cross-banded with 
eray and dark brown; bill black, cere and feet orange. Africa from the Sahara to Cameroon and 
Uganda. 
Biittikofer found this a very shy hawk, and records but three specimens: a 
female from Fisherman Lake, a second from Mt. Olive, and a third from Robert- 
port. We did not identify it. In southeastern Sierra Leone, however, Kemp 
(1905) regarded it more common than Hartlaub’s Hawk, which may indicate 
that it is a frequenter of more open country. 
Dryotriorchis spectabilis spectabilis (Schlegel). Gold-Coast Serpent-eagle 
Astur spectabilis Schlegel, Ned. Tijdschr. Dierk., vol. 1, p. 131, pl. 6, 1863: Gold Coast, St. George 
Elmina. 
Size of a goshawk; adult dark brown to slaty above, white below, with a black streak on chin. 
Immature, dusky brown above, tail with several dark cross-bars; chest feathers with large, black 
tips; thighs barred black and white, central feathers of chin narrow, black. Feathers of sides of 
head elongated, tail proportionally very long. Liberia to Cameroons. 
This rare hawk is confined to the forest area of the west coast of Africa. 
Bittikofer (1886, p. 246) was the first to record it from Liberia on the basis of a 
female shot on the Du River, December 22, by Stampfli and believed to be then 
the third known specimen. Later (1888) he secured a wounded bird at Schieffel- 
insville and kept it alive for some two months, feeding it on the bodies of birds, 
especially of weavers. In 1899, Oberholser recorded the ninth known specimen, 
a female shot by Currie in the forest near Mount Coffee. He notes that it was 
unsuspicious and was in the act of eating a green snake when killed. Coolidge 
and I secured a female in immature plumage on the Du River, August 15. As 
we were making our way up-stream in a large dugout, the bird flew from the 
forest on our left and alighted in the thickest part of a leafy bough overhanging 
a dark pool of the stream. We did not see other specimens, but in the dense 
forest growth which it haunts, it might easily escape notice. 
Cuncuma vocifer (Daudin). African Sea-eagle 
Falco vocifer Daudin, Traité d’Ornith., vol. 2, p. 65, 1800: Keurboom River, Cape Colony. 
Large, length about 29 inches; head, breast, back, and tail, and the longer under tail-coverts 
white; wings, shoulders, rump black with steely reflections; belly, legs, and shorter under tail- 
coverts reddish brown; bill black, cere yellow, legs yellow or whitish gray. Africa south of the 
Sahara. 
The only record for Liberia is that of Biittikofer who records one taken by 
Stampfli on the Junk River. Its stomach contained fish bones. Probably this 
loud-voiced bird avoids the forested areas to a large degree.
