168 FALCONIFORMES CHAP. 
U. anthracina, found from Arizona and Texas to northern South 
America, has in addition a white belt across the rectrices. 
The crested Harpyhaliaétus coronatus, extending from Bolivia 
and Brazil to Patagonia, a powerful and savage bird with a taste 
for carrion, is chocolate-brown, with grey on the wing, and a tail 
like that of the last species; H. solitarius, darker in colour and 
doubtfully distinct, reaching Mexico northwards. Heterospizias 
meridvonalis, of northern South America to Bolivia and Paraguay, 
is mottled with rufous, grey, and black, and has two white bands 
on the tail. Buteogallus aequinoctialis, of Guiana and Colombia, 
is black relieved with rusty above, and reddish with black bars 
below, the remiges being chiefly chestnut, and the tail indis- 
tinctly barred with white. Busarellus nigricollis, of Guiana and 
Brazil, is brighter chestnut with black streaks, the head being 
buffish, the lower throat, primaries, and most of the tail black. 
It has a harsh cry, and loves sitting on stumps near water, while 
the rugose soles of the feet assist it to secure the fishes and 
molluses on which it—as well as Buteogallus—teeds. 
Of the forms with comparatively weaker feet, Haliastur indus, 
the “Brahminy Kite” or “ Pondicherry Eagle,” reaching from 
the Indian Region to Australia and New Guinea, is chestnut with 
darker wings, the white head, neck, and lower parts being 
streaked with black; HL sphenurus, of the two latter countries 
and New Caledonia, named by colonists the “ Whistling Kite,” is 
ashy-brown, with rufous head and ochraceous breast striped with 
brown. The note is shrill, the flight easy and buoyant, the food 
composed of garbage, small mammals, birds, lizards, frogs, crusta- 
ceans, insects and their larvae; while fish are secured by grasping 
them with one foot during gliding movements along the surface 
of the water. The Australian species attacks poultry, but is of 
great utility in devouring caterpillars during insect-plagues. The 
nest of twigs, lined with grass, roots, hair, or green leaves, is 
adorned with rags and the like, the two or three eggs being 
greenish-white, rarely with rusty markings. 
Milvus ictinus, the Red Kite or Fork-tailed Glead of the Old 
World, ranging from the Atlantic Islands—except, perhaps, the 
Azores—through most of Europe to Palestine, Asia Minor, and 
Northern Africa, but leaving the northerly districts in autumn, 
is red-brown above and rusty-red beneath, the lower surface and 
the whitish head being streaked with dark brown. It is still
