Breeding

Bottle-shaped mud nests are built under eaves of houses, under bridges, and on the walls and roofs of caves. Breeding recorded in May and June.

The nest is made from mud and includes a long tunnel. The clutch consists of 4-5 white eggs; both adults build the nest, incubate the eggs and care for the young.

Diet

The diet consists of flying insects, cicadas and mosquitoes.

They feel alone or in small groups.
