Western House-Martin

Distinctive small swallow with blue-black upperparts, a big white rump patch, and snow-white underparts. Juvenile in late summer and autumn is duller above and dingier below than adult. Compare with other swallows; note the relatively shallowly forked and streamerless tail, as well as jerky and fluttery flight. In east of range, overlaps with very similar Siberian House-Martin (formerly treated as one species); note present species’ significantly smaller rump patch. Breeds colonially, frequently building mud nests under the eaves of buildings; forages over varied open and semi-open habitats, especially water bodies and adjacent fields. Gives a soft burbling trill.

The preferred habitat of the western house martin is open country with low vegetation, such as pasture, meadows and farmland, and preferably near water, although it is also found in mountains up to at least 2,200 m (7,200 ft) elevation.

The house martin has a flat and wide beak, perfect for catching insects like flies, beetles, and aphids. As house martins eat winged insects they catch whilst in flight, they cannot be attracted to gardens by putting out food in the same way as many other songbirds.
