Tepui Swift

The tepui swift is one of the smaller members of genus Streptoprocne. It is 14 to 16 cm (5.5 to 6.3 in) long and weighs about 20 to 24 g (0.71 to 0.85 oz). It has a long deeply notched tail and long broad wings. Adult males' most obvious feature is the wide orange-chestnut collar that encircles the neck and includes the upper breast, chin, throat, and most of the face. The rest of its plumage is sooty black, at times with a few white feathers on the breast below the collar. Adult females are similar to males though some have a paler breast with brown mixed in. Voice: The tepui swift appears to have two flight calls, "a squeak followed by a trill and short squeals, squeek, titititititititi sui, squi, squi..." and "a slow series of reedy or hissing tic notes".
