Blue-crowned Laughingthrush

One of the largest of the frigatebirds; females are larger than males. Adults are easier to separate from similar frigatebirds than younger birds. Adult males are all black with a white oval belly patch and white spurs emanating outwards from the body onto the wing. Adult females have a black throat with a white hind collar, breast, and belly. The white spurs on the wing are angled forwards. Juvenile and immature plumages are variable and are best separated from other frigatebirds by size when comparison is possible. Breeding restricted to Christmas Island and usually silent unless breeding. Stragglers appear far away from the breeding colony in parts of Indian and Eastern Pacific Oceans.

Unique and spectacular hummingbird of the upper humid montane forest in Bolivia. Plumage mostly black, with striking white feathers on breast and a shining blue rump. Occurs to, and sometimes just above, treeline on the east side of the Andes from western Santa Cruz department to La Paz. The only black hummingbird in its range. This species is generally patchily distributed, but can be locally common, especially where flowers are abundant.

A round-bodied, short-tailed, long-legged terrestrial bird with a red belly. Broad, iridescent blue chest band is bordered with thick black lines. Reddish-brown crown shows an indistinct blue line. Also shows paler brown cheeks and green upperparts. Juvenile is brown with a pale bill base and gray eyes. Singles or pairs forage on forest floor in lowlands and foothills. Unmistakable in limited range on Sulawesi and adjacent islands. Song is a drawn-out, two-part whistle with a longer, trembling first note followed by a falling, mournful note: “waaaaaaaop-wooowow,” as is typical of the genus.
