The sand martin (Riparia riparia ), also known as the bank swallow (in the Americas), collared sand martin, or common sand martin, is a migratory passerine bird in the swallow family. It has a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries and across the Palearctic to the Pacific Ocean. It is a Holarctic species also found in North America. It winters in eastern and southern Africa, South America, and the Indian Subcontinent.

The Sand martin is a small migratory bird in the swallow family. It is brown above and white below with a narrow brown band on the breast. Its bill is black and the legs are brown. The brown back, white throat, small size, and quick jerky flight of the Sand martin separate it at once from similar swallows, such as the Common house martin, the American cliff swallow.

Sand martins have a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries and across the Palearctic to the Pacific Ocean. They are also found in North America. Sand martins winter in eastern and southern Africa, South America, and the Indian Subcontinent. These birds are generally found near larger bodies of water, such as rivers, lakes, or even the ocean, throughout the year. They forage in open areas such as grassland and farmland and tend to avoid dense forests and mountainous areas.

Sand martins are very social birds that live and nest in colonies. They are active during the day and spend their time foraging, preening, and often sunbathe in groups. At night they gather in communal roosts. Sand martins are fast and agile fliers. They rarely land on the ground and are often seen perching or in flight. These birds usually forage in the morning singly or in groups; they catch insects on the wing and occasionally on the ground or over the water. Sand martins constantly communicate with each other; their twittering song is continuous when the birds are on the wing and becomes a conversational undertone after they have settled in the roost. The harsh alarm is usually heard when a passing falcon, crow, or other suspected predator requires combined action to drive it away.
