Physical description Click here for a physical description Sand Martins are the smallest European species of swallow. The plumage of the two sexes is identical. The cap and sides of the head are brownish-grey, as is the mantle, while most of the front, except for a broad brownish-grey chest band, is white from throat to undertail coverts. There are also some buff-grey to off-white edges on the frons, towards both the upper mandible of the bill and the eyes. The primaries are darker brownish-grey than the rest of the upperparts. The irises are dark; the short, pointy bill is dark-grey. The legs and feet are grey. Juveniles have lighter tips on their wing coverts, lighter margins on their secondaries and some striation on the cap. The throat is grey-buff, while the breast band is not well-developed yet.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Sand Martin is available HERE . There are eight races of Sand Martin, which are a strongly migratory species. Taken altogether, their breeding range encompasses all continents of the northern hemisphere, plus Iceland. Their breeding range extends to the Arctic circle, e.g. in Alaska and northern Scandinavia. They spend the northern winters in tropical and southern areas, from Africa to the Indian subcontinent and in central to southern America. During their migration they can be found basically anywhere between breeding grounds and winter quarters, e.g. also along the Arabian coastal fringe. Nominate race "riparia" breeds across all of Europe, including the British Isles (but except the northern Scandinavian coastal fringe), around the Mediterranean (including the north-western African fringe) and all across temperate Asia, up to a latitude of about 70 degrees. This population migrates southward to spend the northern winters in eastern and southern Africa. During the breeding season Sand Martins are found almost anywhere in Europe, from the British Isles and Iberia in the West to the Ural mountains and the Caucasus mountains in the East and South-east. The only exceptions are mountainous areas in the Mediterranean, the highest mountain ranges in general, and the northern Scandinavian coastal fringe. Sand Martins are usually found near undercuts along rivers with exposed steep sandy banks, into which they dig tunnels for nesting.

Sightings Click here for sighting information Race "riparia" D. Wilczynska reports spotting Sand Martins, nominate race "riparia", along the river Bug, near Brok, Masovia, Poland, in May 2017. J. Pires reports finding Sand Martins, race "riparia", regularly during the breeding season in the area of Mora, Evora, Portugal, where they breed annually. G. Normand spotted Sand Martins, race "riparia", at Parc du Sausset, 20 km North of Paris, France, in July 2020. They were also found near Vannes, Bretagne, France, in August 2020.

Sand Martins are the only Eurasian swallows or martins to use a tunnel for nesting. They can sometimes be found nesting in close proximity to several other tunnel-nesting species, such as European Bee-eaters.

Tunnels can be very shallow, more like a recess or a ledge, while others are up to 1 m long. Note the wide entrances which offer little protection against predators (while other species cut the opening to their tunnels as narrow as possible).

Like all other swallows known to us, Sand Martins are insect hunters. They feed in-flight on small insects.
