Yellow-billed Malkoha

Chunky, short-legged heron. All white with a black-tipped blue bill and bright red legs in breeding plumage. Dark brown with white wings and belly in non-breeding plumage. Found in a variety of freshwater wetlands, though generally rare. Distinctive in breeding plumage, but easily confused with Squacco Heron in non-breeding plumage, when Malagasy Pond-Heron can be carefully distinguished by the much darker brown color on most of the body, which contrasts sharply with the white belly and wing.

A small sunbird with a relatively short, slightly downcurved bill. Males are colorful, with green and blue iridescence on the head and breast and a maroon band above the black belly. Females are fairly drab, with streaked dull-yellow underparts. Found in all habitats on the island of Anjouan in the Comoros. In its small range, it is the only sunbird, so it is easily identified by its bill shape. The song is a typical sunbird jumble of high-pitched notes, and the call is a rising whine. 

Tiny rail, the size of a sparrow and nearly impossible to see without tremendous effort. Slate gray overall with a piercing red eye, brown nape, and white spotting on wings. Beware confusion with downy young of other rail species, which are entirely black. Inhabits drier areas in fresh and saltwater marshes with cattail, sedge, and other tall grasses. Typically rare even in proper habitat. Incredibly difficult to locate even when vocalizing within mere feet of an observer; stealthily dashes around at the base of dense grass like a ninja. Easiest to detect by its distinctive song, most often heard at night: a churring "kick-ee-derr", two higher notes followed by a lower note.
