Collocalia esculenta (Linneaus, 1758) . Glossy Swiftlet

Common, but at lower abundance than Uniform Swiftlet. Habitat seemed to help separate Glossy Swiftlet from Uniform Swiftlet. Glossy Swiftlet was frequently observed foraging low, under the canopy, in dense forest, and in smaller numbers. Identification: ‘Glossy’ sheen observed in the sun, with dark-purple glossy wings. Small amounts of white contrasted starkly with the overall glossy plumage in flight, giving an apparent ‘rump’, although the dorsum was mostly dark gloss above, as the white did not complete a full rump patch. Compare with descriptions of Uniform Swiftlet and White-rumped Swiftlet above.
