What is a "sand martin"?

A sand Martin, also known as the Bank Swallow, is a small migratory bird belonging to the swallow family. These agile birds are primarily found in sandy or loamy habitats near water bodies, such as riverbanks, lakeshores, and coastal areas. Sand Martins are known for their distinctive brown upper parts, white underparts, and a brown band across their chest. They have short, pointed wings and a forked tail, which aids in their swift and acrobatic flight. Sand Martins are insectivorous birds, feeding on flying insects that they catch in mid-air. They are also skilled diggers and create nesting burrows in sandy or soft soil banks, often in large colonies. These burrows provide protection for their eggs and nestlings.
