Genus Delichon is a taxonomic classification for small birds commonly known as house martins. Other synonyms for Genus Delichon include Delichon urbicum, which refers specifically to the white-bellied house martin, and Delichon nipalense, which is the scientific name for the Nepal house martin. These birds are characterized by their swift and agile flying abilities, with their streamlined bodies and pointed wings allowing them to easily catch insects in mid-air. House martins are also known for their distinct nest-building abilities, creating mud nests on the sides of buildings and under eaves. With their unique physical and behavioral traits, it is no wonder that Genus Delichon is a popular subject of study for ornithologists and bird enthusiasts alike.
