The Sand Martin, known as the Bank Swallow in the Americas, is a diminutive and agile bird, a member of the swallow family. Its upper parts are cloaked in a modest brown, while its underparts are a stark white, bisected by a slender brown band across the breast. The bird's bill is a deep black, and its legs are a shade of brown. Juveniles can be distinguished by the rufous fringes on their coverts and the edges of their secondary feathers.

With a length of 12-14 cm and a wingspan of 25-33 cm, the Sand Martin is a small bird that can be readily identified by its brown back, white throat, and the distinctive narrow brown band on its breast. Its flight is characterized by rapid, jerky movements that set it apart from other swallows.

Sand Martins are commonly found near large bodies of water, such as rivers, lakes, or oceans, where they can be seen darting gracefully over the water's surface.

This migratory passerine has a broad summer range that spans Europe, the Mediterranean, and across the Palearctic to the Pacific Ocean. It is also a Holarctic species present in North America. During the winter months, it retreats to the warmer climates of eastern and southern Africa, South America, and the Indian Subcontinent.

Sand Martins are social birds, often nesting in large colonies where hundreds of pairs may reside in close proximity. They are early migrants, arriving at breeding grounds before many other swallows and departing by the end of September. Their flight is a delightful spectacle, with swift and erratic movements as they hunt for insects over water bodies.

The Sand Martin's vocalizations include a continuous twittering song while in flight, which softens to a conversational murmur when perched. They also emit a harsh alarm call in response to potential predators.

These birds exhibit a strong preference for nesting in sandy hills or loess banks, where they excavate tunnels to lay their eggs. The breeding season typically sees them produce two broods, with each clutch consisting of four to five pristine white eggs.

The Sand Martin can be confused with the Banded Martin of sub-Saharan Africa, but the latter is only present in the Sand Martin's wintering grounds.

Their diet primarily consists of small insects, particularly gnats and other flies that have aquatic larval stages.

The Sand Martin is globally recognized as a species of Least Concern by the IUCN, although it is noted that their numbers are decreasing. Some populations are under threat due to habitat loss and are protected under national and local conservation laws. In Canada, for instance, the species is listed as Threatened due to a significant population decline.

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.
