The Welcome Swallow is metallic blue-black above, light grey below on the breast and belly, and rusty on the forehead, throat and upper breast. It has a long forked tail, with a row of white spots on the individual feathers. These birds are about 15 cm (6 in) long, including the outer tail feathers which are slightly shorter in the female. The call is a mixture of twittering and soft warbling notes, and a sharp whistle in alarm.
Young Welcome Swallows are buffy white, instead of rufous, on the forehead and throat, and have shorter tail streamers.Rujukan@ http://en.wikipedia.org/wiki/Welcome_Swallow
