Pearl-breasted swallow

The pearl-breasted swallow (Hirundo dimidiata) is a small swallow. It breeds in southern Africa from Angola, southern Zaire and Tanzania southwards. It is partially migratory with many birds from the south west of South Africa wintering further north.

This is a bird of dry scrub, farmland and clearings. It is often found around human habitation. The pearl-breasted swallow builds a bowl-shaped mud nest reinforced with grass or hair and with a soft lining. It sometimes uses old nests of the greater striped swallow, Hirundo cucullata.

The nest may be reused in later years, and one was utilised for 30 years. The nest is built in natural cavities or man-made structures such as buildings, culverts and shafts, but its preference for isolated and abandoned buildings means that this species has not benefited from artificial sites to the same extent as, for example, the greater or lesser striped swallows.

The two or three eggs are pure white, and are incubated by the female alone for 16–17 days to hatching. Both parents then feed the chicks. Fledging takes another 20–23 days, but the young birds will return to the nest to roost for a few days after the first flight.

The pearl-breasted swallow is 13–14 cm long. It has glossy blue upperparts and grey-white underparts. The upper wings, underwing flight feathers and forked tail are blackish-blue. The underwing coverts are a darker shade of grey-white. The lack of white in the tail is a distinction from similar Hirundo species. The outer feathers are slightly longer in the male than the female. Juveniles are duller and browner than the adult, with shorter outer tail feathers.

The northern subspecies, H. d. marwitzi is darker and smaller than nominate H. d. dimidiata, but the differences are small, and the species may be monotypic.

The pearl-breasted swallow is sparsely distributed, but can be locally common. It feeds mainly on flying insects, with a fast direct flight. The call is a chittering chip cheree chip chip.

Red-throated cliff swallow, Petrochelidon rufigula

South African cliff swallow, Petrochelidon spilodera

Genus Pseudhirundo:

Grey-rumped swallow, Pseudhirundo griseopygaThere are many other African birds in the swallow family Hirundinidae, but not called swallows, such as the Saw-wings (genus Psalidoprocne, also called rough-winged swallows), and numerous martins, such as the African river martin (Pseudochelidon eurystomina).

The bird genus Hirundo is a group of passerines in the family Hirundinidae (swallows and martins). The genus name is Latin for a swallow. These are the typical swallows, including the widespread barn swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts. With fifteen species this genus is the largest in its family.

The saw-wings, Psalidoprocne, is a small genus of passerine birds in the swallow family. The common name of this group is derived from the rough outer edge of the outer primary feather on the wing, which is rough due to recurved barbs. The function of this is unknown.
