White-throated Gerygone

Fairly small tanager of pine-oak and tropical forest in foothills and highlands of Mexico; endemic. Found mainly in the canopy, usually in pairs or small groups that sometimes join mixed-species feeding flocks. Distinctive male has brilliant red head (with small black mask), greenish upperparts, and yellow underparts. Female is rather drab greenish and yellow overall with dusky gray cheeks. Female looks similar to female Hepatic Tanager but much smaller with smaller, stubbier bill and paler belly. Calls are high twitters similar to Bushtit.

Chunky, dark gray bird with a dark face. Dark face patch is more extensive on males than females; males on Sumatra have entirely black heads. Inhabits moist foothill and montane forest. Moves through the upper levels of forest, often with other species in mixed flocks. Gives various high squeaky calls, including an inflected “weee-tee!”.

A plump, small-headed, pigeon-like bird. Mostly chestnut-cinnamon speckled with white; the male has a gray face and yellow spectacles, and the female has a yellowish face. It prefers foraging on the ground for seeds in semi-arid woodland on red Kalahari sands, where it can be inconspicuous. Gathers in large groups at drinking sites in the morning. The soft “chuup-chuup chop-chop” call is diagnostic.
