658 REPORT OF THE HARVARD AFRICAN EXPEDITION 
number of specimens from the St. Paul’s, Farmington and Du rivers. He speaks 
of seeing them in small family parties of from three to five birds in dense but 
not high forest. It is not as shy as most hawks. In southeastern Sierra Leone, 
Kemp (1905) secured two young in February and April. 
Urotriorchis macrourus macrourus (Hartlaub). Long-tailed Hawk 
Astur macrourus Hartlaub, Journ. f. Ornith., vol. 3, p. 353, 1855: Dabocrom, Gold Coast. 
Length about 24 inches; general color slaty gray, paler on head, neck, and breast; throat, 
belly, under and upper tail-coverts white; tail black with white cross-bars and tip; cere and feet 
yellow. Female with the under surfaces reddish brown. Gold Coast to Gaboon. 
The Long-tailed Hawk is included by Biittikofer in his list of Liberian birds 
as having been collected by Schweitzer, but the identity requires confirmation. 
Circus macrourus (S. G. Gmelin). Pale Harrier 
Accipiter macrourus 8. G. Gmelin, Nouv. Comm. Acad. Petrop., vol. 15, p. 439, pls. 8, 9, 1871: 
Veronetz gouv. to Volga. 
Length 17 inches; above pale blue-gray, cheeks and eyebrows white, upper tail-coverts white 
with gray bars; below white; middle tail-feathers gray, the others with white and gray cross- 
bands; female and immature male brownish; bill black, cere and feet yellow. Breeds in Europe 
and Asia, migrating in winter to Africa from Sudan and Gambia south to Cape Colony. 
Probably most of Liberia is too covered with forest and thicket growth to be 
attractive to open-country birds such as harriers, hence this species is uncommon 
there and then only as a winter resident near the coast. The only record is that 
of Biittikofer (1885, p. 151) who secured two young males at Cape Mount in 
November. 
Gymnogenys typicus pectoralis (Sharpe). West African Harrier-hawk 
Polyboroides pectoralis Sharpe, Bull. Brit. Orn. Club, vol. 13, p. 50, 1903: Efulen, Cameroons. 
Length 25 inches; adult blue-gray, belly, thighs, and upper tail-coverts barred black and white; 
tail black with two bars and tip white, speckled with brown; primaries black, secondaries gray 
with black tips; scapulars gray with a black subterminal spot. Neck-feathers elongated. Feet 
and the long tarsus yellow. Immature, a general dark brown, tail with three or four dark bars; 
thighs barred, yellowish or buff and dusky. The region around the eye is naked, and orange-colored. 
Portuguese Guinea to Cameroons. 
This bare-faced hawk is frequently seen in Liberia, usually in pairs frequent- 
ing the vicinity of plantations and clearings, or soaring overhead. In its adult 
plumage of blue-gray with the ruff of long feathers around the back of the neck 
it is a handsome bird. Near our camp on the Du, a pair was frequently seen, one 
of the birds sometimes coming to the stumps still standing after the clearing of 
the forest, to watch for prey. They were wary, however, and seldom came within 
gunshot. At Paiata we saw another walking about on the ground as if in search 
of food, and it is not unlikely that they hunt about on the ground a good deal 
for their long legs are well suited for this. Indeed, our first specimen had been 
caught in a native ground-snare. One shot at Gbanga had in its stomach the 
remains of insects as well as kernels of the oil palm, doubtless swallowed for the 
oily pulp surrounding them; the other contained the remains of a large Mantis. 
Fischer mentions seeing one searching in the holes of a palm trunk and we saw a
