hill swallow
The hill swallow (''Hirundo domicola'') is a small passerine bird in the swallow family. It breeds in southern India and Sri Lanka. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. It was formerly considered a subspecies of the Pacific swallow.
This species is a small swallow at 13 cm. It has a blue back with browner wings and tail, a red face and throat, and dusky underparts. It differs from barn swallow and the closely related welcome swallow in its shorter and less forked tail.〔
The hill swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on a man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is up to four eggs. It is similar in behaviour to other aerial insectivores, such as other swallows and the unrelated swifts. It is a fast flyer and feeds on insects, especially flies, while airborne.〔
