Mountain Grackle

Macroagelaius subalaris

Scarce blackbird found only at higher elevations in the northern half of Colombia’s eastern Andes. It is quite slender and nearly all black, but has a maroon patch under the shoulder which is mostly hidden from view when the bird is perched. The dark bill and eye help to separate it from other similar species if the wing patch is not visible. Usually seen in the forest canopy and may congregate in large flocks. Song is a chaotic series of sharp, shrill notes mixed with clacking calls.

Resident species

保护状况

It is threatened by habitat loss and declining in numbers. It was uplisted from Near Threatened to Critically Endangered status in 2000, due to fears of a collapse of the presumably tiny population. As the species, while still severely declining, has turned out to be more widespread than believed, it was downlisted to Endangered in the 2007 IUCN Red List.

White-collared Starling

White-collared Starling

Grafisia torquata

The male is an unusual and beautiful starling that is glossy blue-black with a broad white collar. Females are duller, gray with paler mottling on the underparts. Both sexes have a yellow-orange eye. Found locally in savanna, montane grassland, and areas with a mix of savanna and forest. Often in small flocks, sometimes mixed with other starling species. The male is unmistakable; the female might be confused with other starlings, but is identified by the gray plumage without gloss, the short tail, and the yellow-orange eye. The calls include chirps and short whistles. 

Yellow-rumped Antwren

Yellow-rumped Antwren

Euchrepomis sharpei

Small gray-and-yellow bird found in rainforest canopy. Has a gray head, a greenish-yellow body, and bold yellow wingbars; males also have a black cap and a narrow black eye-line. Found in the canopy of montane forest, where individuals and pairs may be found foraging with mixed-species flocks. Compared to the similar Rufous-rumped Antwren, notice its yellow lower back and rump (reddish in Rufous-rumped). Its song is a high, accelerating series of chip notes.

Aldabra Drongo

Aldabra Drongo

Dicrurus aldabranus

Bold, black fork-tailed bird with a red eye. There is sometimes but not always a tuft of long feathers above the bill. Juveniles have an unusual pale-gray plumage, but still show the forked tail. Found in all habitats with bushes and trees on the remote Seychelles island of Aldabra, including forest, mangroves, and thick scrub. Perches prominently in the open, swooping out to catch insects on the wing. Often follows Madagascar Coucals and Aldabra Giant Tortoises, feeding on insects that they disturb. Song is a repeated sequence of whistles, creaks, and rasps.
