The Nepal House Martin ( Delichon nipalensis , Syn. : Delichon nipalense ) is a bird art from the family of swallows (Hirundinidae). In addition to the house martin, which is also native to Central Europe, and the Asian house martin, it is the third species that is assigned to the genus Delichon . Two subspecies are described for them.
The Nepalese swallow is very similar in appearance to the house martin. Like these, she has a black and blue side of the body, a white underside of the body and a white rump. The most important external distinguishing feature from the house martin is the blue-black throat, i. H. the blue-black head plumage extends over a larger part of the head of the Nepalese swallow. Another distinguishing feature is the clearly more straight tail end.
The distribution area of the Nepal Swallow extends in the Himalayas over Nepal , northeast India , Bangladesh to the west and north of Burma and Tonkin . In this distribution area it breeds at an altitude of 1000 to 4000 meters. Their main distribution area is 1000 to 3000 meters. She builds her nests on vertically falling rocky cliffs, which must be free of vegetation so that the clumps of clay and earth from which the Nepalese swallows build their hemispherical nest stick to the rock. Unlike the house martin, Nepalese swallows are resident birds ; outside of the breeding season, however, their foraging flights lead them down to a depth of 350 meters above sea level. They live exclusively on insects that they hunt in flight.
The breeding season varies depending on the distribution area and altitude. In Nepal, the first Nepalese swallows begin to breed as early as March; the last breeding pairs brood in June. In Burma, on the other hand, the breeding season is reduced to a shorter period. The Nepalese swallow pairs breed here from April to May. Both sexes are involved in nest building, the incubation of the clutch and the rearing of the young.
