Pseudochelidon eurystomina
SUBFAMILY
Pseudochelidoninae
TAXONOMY
Pseudochelidon eurystomina Hartlaub, 1861, Gabon.
OTHER COMMON NAMES
English: Congo swallow; French: Hirondelle de riviиre; German:
Trugschwalbe; Spanish: Aviуn de Rнo Africano.
PHYSICAL CHARACTERISTICS
5.5 in (14 cm). The plumage is glossy black overall and the
beak, feet, and eyes are colored red.
DISTRIBUTION
Breeds in coastal Gabon and inland along the Congo River and
other large tropical rivers of central western Africa. After
breeding it migrates far up the Congo River and other major
watercourses in the region. It occurs in Congo, the Democratic
Republic of Congo, and Gabon.
HABITAT
Breeds in sandy places along forested tropical rivers and in
coastal tropical savanna. After breeding it migrates inland
along large forested rivers, where it often roosts on sandy bars
and embankments.
BEHAVIOR
The species is highly gregarious when breeding and also during
migration. It defends a local territory around the nesting
site, and attracts a mate by aerial displays and singing.
FEEDING ECOLOGY AND DIET
Feeds on flying insects caught on the wing.
REPRODUCTIVE BIOLOGY
Monogamous. Populations breeding on large rivers breed during
the drier season, when sandy riverbanks are exposed. Populations
breeding in coastal savanna breed from about September
to November. Colonial nesting sites are in sandy embankments,
dunes, and islands of large tropical rivers and coastal savanna. It
digs a slanting tunnel of 6.6–10 ft (2–3 m) into soft ground for
its nesting site. The clutch size is two to four eggs. Both parents
share in the incubation and care of the young.
CONSERVATION STATUS
A rare, little-known, but locally abundant species that is listed
as Data Deficient.
SIGNIFICANCE TO HUMANS
African river-martins have been recently hunted in significant
numbers by local people as a source of food. Otherwise, they
are of no direct importance to humans, except for indirect economic
benefits of ecotourism involving rare birds.
