The typical nest is a grass or feather-lined deep closed mud bowl with a small opening at the top, [12] but many Asian house martins leave the top of the nest open. [ 20 ] [ 21 ] [ 22 ] David Winkler and Frederick Sheldon believe that evolutionary development in the mud-building swallows, and individual species follow this order of construction.
It is much more urban than the barn swallow, and will nest even in city centres if the air is clean enough. [14] It is more likely to be found near trees than other Eurasian swallows, since they provide insect food and also roosting sites. This species does not normally use the reed-bed roosts favoured by migrating barn swallows. [16] [17]

The wire-tailed swallow is a member of the genus Hirundo, a cosmopolitan group of "barn swallows". It has two subspecies: [5] H. s. smithii was first described by William Elford Leach and K. D. Koenig in 1818. [6] Known as the African wire-tailed swallow, it is found throughout Africa. [5] H. s. filifera was first described by Stephens in 1826. [6]
The cliff swallow or American cliff swallow (Petrochelidon pyrrhonota) is a member of the passerine bird family Hirundinidae, the swallows and martins. [2] The generic name Petrochelidon is derived from the Ancient Greek petros meaning "stone" and khelidon (χελιδών) "swallow", and the specific name pyrrhonota comes from purrhos meaning "flame-coloured" and -notos "-backed".
