Synonyms for this bird include Delichon nipalense, Hirundo nipalensis, and Hirundo urbica. The Common House Martin is a small bird that typically nests in colonies under the eaves of houses. They are often confused with swallows due to their similar physical appearance, but can be distinguished by their shorter tails and lack of a tail fork.
