| Tachycineta albiventer (Boddaert, 1783) |
The White-winged Swallow, Tachycineta albiventer, is a resident breeding bird in tropical South America from Colombia, Venezuela and Trinidad south to northern Argentina.
This swallow builds a cup nest lined with feathers in a tree hole, between boulders or in man-made structures. The clutch is 3-6 white eggs.
The adult White-winged Swallow is 13.2 cm long and weighs 17 g. It has iridiscent blue-green upperparts, white underparts and rump , and white edgings to the secondary flight feathers. The sexes are similar, but juvenile plumage is grey brown above apart from the white rump.
White-winged Swallow is easily distinguished from the related Tree Swallow, which has occurred within its range, by the white in the wings; this is lacking in the otherwise quite similar northern species.
White-winged Swallow is usually found near water, and feeds primarily on fling insects. It normally occurs in pairs or small flocks. The call is a harsh chirrup.
