below than the nominate race, and is only faintly streaked on the rump. This species, particularly subspecies ''mayri'', is very similar to the red-rumped swallow of the race ''japonicus'', but is larger, more heavily streaked, and has a less distinct neck collar.

Behavior

The contact call is ''pin'', the alarm is ''chi-chi-chi'', and the song is a soft twittering.

Migration

The island subspecies are essentially resident, but the continental races ''mayri'' and ''stanfordi'' are partial migrants which move south in the winter.

Breeding

The striated swallow breeds from April to July alone or semi-colonially with scattered nests. The nest is a retort or bottle-shaped structure, made from mud pellets and lined with dried grasses and feathers. The clutch is usually four, sometimes five, white eggs. Both sexes build the nest, and share incubation and the care of the young. Nests are constructed in natural caves, but very often in artificial sites on bridges, in culverts and on buildings.

Feeding

The striated swallow feeds low over the ground or at cliff faces on flying insects. It has a slow buoyant flight compared to the
