ID tip

The ridgetop swiftlet is 9–10 cm (3.5–3.9 in) in length with a square tail. The back and upper surface of the wings are a dark dull blue with a moderate green gloss. The rump is sometimes slightly paler due to the white margins of feathers forming the uppertail coverts. The throat and upper breast are dark grey with fine white scalloping merging into larger greyish chevrons over the lower breast and flanks, becoming white over the belly. There is sometimes a tuft of small feathers on the hallux, the rear facing toe.
