Hawaii Creeper

A small, relatively drab bee-eater of arid country. Note the blue eyebrow, black face mask, white throat, and buffy underparts. In flight, reveals buffy underwings with black tips. Generally uncommon in dry savanna and thornscrub. Often in pairs. Similar in size to Little Bee-eater, but easily separated by white throat and more washed-out overall coloration. The call consists of quiet whistling notes. 

Nest parasite that lays its eggs in the nests of Red-billed and Brown firefinches. Breeding males are glossy black, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The color of the bill is red in southeast Africa and whitish in western, northern, and central Africa. Found in savanna, scrub, farmland, and towns. Mimics the vocalizations of its host firefinches: low rattling series and high-pitched whistled notes. In southeast Africa, can be separated from other indigobirds by its red bill. Very similar to other indigobirds elsewhere on the continent. Breeding males can be separated by their all-black wings that lack a pale brownish panel. The mimicked vocalizations of its host species can also help confirm identification. In non-breeding plumage, similar to non-breeding Pin-tailed Whydah but separated by red legs.

Small yellowish bird; note bold wingbars and face pattern with short pale eyebrow and arc under the eye. Yellow underparts sometimes bright, sometimes paler whitish, but always some yellow tones. Could be mistaken for a tyrannulet but note thicker bill and more horizontal posture. Usually seen singly or in pairs, following a mixed-species flock through forest, edge, and second growth. Found at relatively high elevations in its limited range. Song is a slow series of short phrases, like a squeaky Yellow-throated Vireo.
