Green-crowned Warbler

Uncommon within restricted range of the Magdalena Valley of central Colombia, from around 200 to 1,000 m. Occurs in open woodlands. Males are dark steely-blue above and rich yellow below, with a yellow forecrown. Note entirely dark throat and dark underside of tail. Female is dull grayish olive above and yellow below. Note yellow forecrown on female. Could be confused with Orange-bellied Euphonia; male Orange-bellied has white underside of tail and females are grayer below.

Largish hawk with a short tail and very broad wings. White head, belly and tail with a barred black back. Similar to White-necked Hawk but larger, with a blue base to the bill, a whiter uppertail and an entirely pale undertail. Juvenile is paler above with a few dark spots on the head. Found in extensively forested landscapes where often seen soaring over the canopy or perched prominently.

Glossy black bird with a long tail, a heavy hooked bill, and a weak tuft of a crest. Inhabits lowland and foothill forests. Moves in pairs and flocks, calling to keep in contact. Sometimes moves with mixed-species flocks. Vocalizations are quite variable, and include a fast series of short rasping notes, as well as various strange whistled notes, often with a musical-instrument-like quality. Formerly grouped with Malayan Black Magpie under the more generic “Black Magpie.”
