Description

Flock Streak Throated Swallows Electric Srirangapatna Jul22 A7C 02169

The streak-throated swallow is a sparrow-sized bird about in length. It has a dull chestnut forehead and crown. The underparts are whitish, the upper feathers are steel-blue. The rump is pale brown and the tail has a square end. The brown streaks on the throat and chest are distinctive and used to differentiate from other similar birds. On cold mornings, large flocks are seen closely-packed on electric wires to catch the early sun. Its voice is a twittering ''chirp'' while perched. In flight, it utters a sharp ''trr-trr''.
