Hirundo smithii
Perched on a dock support at Lake Victoria, Kisumu, Kenya. October 2016.
From Wikipedia: The wire-tailed swallow is a small swallow, measuring 18 cm in length. It has bright blue upperparts, bright white underparts and a chestnut cap. Immature birds lack tail wires, and have dull brown (rather than chestnut) caps. The species is named for the very long filamentous outermost tail feathers, which trail behind like two wires. The sexes are similar in appearance, but the female has shorter "wires".
