Caucasian Snowcock
Tetraogallus caucasicus
Large and heavily-built gamebird of the Caucasus Mountains. Grayish overall, with a whitish face and throat. Also note coarse rusty-brown-and-white streaking on the back and sides. Inhabits the high rocky reaches of the mountains, from the forest’s upper limit up to the snowline; will move down the mountains in response to especially harsh winter snowstorms. Song is a loonlike, desolate, rising whistle. Gives loud “chuk” calls when alarmed.

Akohekohe
Palmeria dolei
A large, rare Hawaiian Honeycreeper of high elevation wet forests on eastern Maui. Its bushy, forward-pointing crest is distinctive. May appear mostly black at a distance or in misty weather. Juveniles are less brightly colored than adults. Usually found foraging in the forest canopy giving loud and boisterous songs and calls. The song is a varied series of gurgles, whistles, and buzzes. Aggressively chases other birds away from flowering trees.

Apalis goslingi
A small, slender plain apalis with sooty-gray upperparts, pale gray underparts, a pale throat, and a shortish white-tipped gray-brown tail; eyes are red-brown. Juvenile is paler than adult, with dingy yellowish underparts. A local resident inhabiting middle levels of both primary and patchy degraded forest, especially along streams, in the northeast Congo Basin, where no similar apalises occur. Vocalizations include a rapid, monotonous strident “swit-swit-swit-swit” and “tet-tet-tet.”
