. This is a bird of open country and grassland, with a preference for highlands and nearby water. It is often found around man-made structures.

Breeding

The White-throated Swallow builds a bowl-shaped mud nest with a soft lining of grass or hair. It is usually near or over water, and is built on a ledge under an overhang on a rock face or on a man-made structure such as a building, dam wall, culvert or bridge. Uninhabited buildings are preferred to houses. The nest may be reused for subsequent broods or in later years.

The three eggs of a typical clutch are white with brown and blue blotches, and are incubated by the female alone for 15–16 days to hatching. Both parents then feed the chicks. Fledging takes another 20–21 days, but the young birds will return to the nest to roost for a few days after the first flight. The young can swim a short distance to safety if they fall from the nest.

Feeding

It feeds mainly on flying insects, which it pursues with a fast twisting flight like a Barn Swallow
