Altamira Oriole

A large, extremely long-tailed, dark and glossy starling. Sometimes looks black, but in good light shows iridescence that is mostly blue-green, with a purple belly and tail. Found in a wide variety of savanna habitats as well as in cultivated areas. Often on the ground, typically in small flocks. Similar to Rüppell's Starling, but longer-tailed and more blue-green overall. The loud and complex vocalizations include a mix of rattles, scratches, and piercing whistles. 

Tiny, mostly green bumblebee-like hummingbird with a straight bill, glittering magenta throat, white chest band and sides of rump, and short forked tail. Female very different, with buffy underparts, dark brown ears, and unforked rufous tail with a black band. Found in cloud forest, edges, second growth, and gardens, with some seasonal movements. Often hard to see, but sometimes perches at the top of bare branches. In Andes, compare to the similar Gorgeted Woodstar; male Gorgeted has longer purple feathers on the throat, and female lacks green central tail feathers. At lower elevations compare with Amethyst Woodstar, in which the male has a longer tail and female has a whitish throat and black tail tipped with white. Restricted to Colombia and Venezuela.

A large cuckoo endemic to Sulawesi. Long tail and red eye. Male is all black; females have a brown back andbarred underparts with white stripe on the face. Found in forest and edge where it hides in dense canopy and is difficult to see. The only koel on Sulawesi. Male separated from other black birds by long, pointed black tail. Female from other cuckoos by white stripe on face and barring. Voice a typical “koel!” call, or short series of rising and falling “woo” notes.
