Vv FALCONIDAE 159 
tail-coverts and breast ; 4. pectoralis of Brazil is brownish-black 
above, slightly relieved by white, the tail being greyish with black 
bands, the collar and chest rufous, the fore-neck and abdomen 
white, streaked and barred respectively with black. A. minullus 
inhabits South Africa, A. madagascariensis Madagascar, A. cir- 
rocephalus Australia, Tasmania, and Papuasia, A. chilensis Chil, 
A. guttatus Paraguay and Bolivia, 4. pileatus Brazil, A. collavis 
New Granada; while the very robust 4. cooperi occupies North 
America southwards to Mexico, and A. fuscus the same country to 
Panama. In A. subniger (tinus), of Central and South America, 
and some other species, the young are red above. Lrythrotriorchis 
radiatus of East and Central Australia, a rufous bird with dark 
markings, which lays an egg like that of a Sparrow-Hawk, may 
perhaps be placed here, as may Iegatriorchis doviae of New Guinea, 
in which the blackish upper parts have lighter transverse stripes, 
and the white under parts longitudinal dusky streaks. 
Sub-fam. 4. Aguilinae—tThe long-legged Morphnus guianen- 
sis, ranging from Panama to Amazomia, is black, with three ashy 
tail-bars, brown head and chest, and white rufous-banded abdomen ; 
the fine crest is brown with black. tip, the wing- and tail-coverts 
are varied with white. This bird haunts thick woods near water, 
and in habits appears to resemble the next two genera, which have 
similar soft plumage, short wings and long tails. JL taeniatus of 
Ecuador has broader and blacker bars below. Harpyopsis novae 
guineae of New Guinea, and Thrasaétus haxpyia, the Harpy, extend- 
ing from Mexico to Paraguay and Bolivia, have blackish-grey upper 
parts with a tendency to darker transverse markings; the tail shews 
six black bars; and the white under parts exhibit a greyish zone 
on the chest. The former species is, moreover, relieved by white 
above, while a bifurcated grey crest surmounts the white head 
and neck of the latter. Marvellous stories have been told of the 
fierceness and strength of the last-named, but despite its huge bill 
and legs, it seems never to attack man, though defending itself with 
spirit when wounded. Found in low-lying forests and near rivers, 
it may be seen wheeling in circles with slow heavy flight, or 
digesting its meals on low boughs of trees. The diet consists 
largely of mammals, including fawns, monkeys, foxes and peccaries ; 
the nest is in high trees or cliffs. The Indians are very proud of 
a living specimen, while the down is used for decoration, and the 
feathers for arrow-making. Harpyopsis devours wallabies.
