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.

Taxonomy

This species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae, and originally named Hirundo riparia; the description consisted of the simple "H[irundo] cinerea, gula abdomineque albis" "an ash-grey swallow, with white throat and belly" and the type locality was simply given as "Europa". [3] The specific name means "of the riverbank"; it is derived from the Latin ripa "riverbank". [4]

The pale martin of northern India and southeastern China is now usually split as a separate species Riparia diluta. It has paler grey-brown upperparts and a less distinct breast band. It winters in Pakistan, southern India and Sri Lanka. [5]

Description

The sand martin is brown above, white below with a narrow brown band on the breast; the bill is black, the legs brown. The young have rufous tips to the coverts and margins to the secondaries.

Its brown back, white throat, small size and quick jerky flight separate it at once from similar swallows, such as the common house martin (Delichon urbicum), the American cliff swallow (Petrochelidon pyrrhonota) or other species of Riparia . Only the banded martin (Neophedina cincta) of sub-Saharan Africa is similar, but the sand martin only occurs there in (the northern) winter.

Measurements: [6]

The sand martin's 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 heard when a passing falcon, crow or other suspected predator requires combined action to drive it away.

Ecology

Linnaeus already remarked on this species' breeding habits: Habitat in Europae collibus arenosis abruptis, foramine serpentino"it lives in Europe, in winding holes in sheer sandy hills". It has been observed that sand martins favour loess as a particular type of ground to nest in. [7] Sand martins are generally found near larger bodies of water, such as rivers, lakes or even the ocean, throughout the year. [3] [8]

In Britain, the sand martin appears on its breeding grounds as the first of its family, starting towards the end of March, just in advance of the barn swallow. In northern Ohio, they arrive in numbers by mid-April, about 10 days earlier than they did 100 years ago. [9] [10] At first, they flit over the larger bodies of water alone, in search of early flies. Later parties accompany other swallow species, but for a time, varying according to weather, the birds remain at these large waters and do not visit their nesting haunts. The sand martin departs early, at any rate from its more northerly haunts. In August, the gatherings at the nightly roost increase enormously, though the advent and departure of passage birds causes great irregularity in numbers. They are essentially gone from their breeding range by the end of September.

Their food consists of small insects, mostly gnats and other flies whose early stages are aquatic.

The sand martin is sociable in its nesting habits; from a dozen to many hundred pairs will nest close together, according to available space. The nests are at the end of tunnels ranging from a few inches to three or four feet in length, bored in sand or gravel. The actual nest is a litter of straw and feathers in a chamber at the end of the burrow; it soon becomes a hotbed of parasites. Four or five white eggs are laid about mid-late May, and a second brood is usual in all but the most northernly breeding sites.

Globally, it is not rare and classified as a species of least concern (but noted to be decreasing) [11] by the IUCN. [1] It does have some national and local protections, as certain populations have declined or face threats from habitat loss and fragmentation. In Canada, it is listed as Threatened under Schedule 1 of the federal Species at Risk Act (SARA) due to the loss of 98% of its Canadian population over the past 40 years. [12] They are considered threatened in California, where populations exist in the Sacramento Valley [13] and at two coastal sites, Año Nuevo State Park and Fort Funston. [14]

<span class="mw-page-title-main">Western house martin</span> A migratory passerine bird of the swallow family

The western house martin, sometimes called the common house martin, northern house martin or, particularly in Europe, just house martin, is a migratory passerine bird of the swallow family which breeds in Europe, north Africa and across the Palearctic; and winters in sub-Saharan Africa and tropical Asia. It feeds on insects which are caught in flight, and it migrates to climates where flying insects are plentiful. It has a blue head and upperparts, white rump and pure white underparts, and is found in both open country and near human habitation. It is similar in appearance to the two other martin species of the genus Delichon, which are both endemic to eastern and southern Asia. It has two accepted subspecies.

<span class="mw-page-title-main">Swallow</span> Family of birds

The swallows, martins, and saw-wings, or Hirundinidae are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used as the common name for Hirundo rustica in the UK and Ireland. Around 90 species of Hirundinidae are known, divided into 21 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory.

The Eurasian crag martin or just crag martin is a small passerine bird in the swallow family. It is about 14 cm (5.5 in) long with ash-brown upperparts and paler underparts, and a short, square tail that has distinctive white patches on most of its feathers. It breeds in the mountains of southern Europe, northwestern Africa and across the Palearctic. It can be confused with the three other species in its genus, but is larger with brighter tail spots and different plumage tone. Many European birds are resident, but some northern populations and most Asian breeders are migratory, wintering in northern Africa, the Middle East or India.

The rock martin is a small passerine bird in the swallow family that is resident in central and southern Africa. It breeds mainly in the mountains, but also at lower altitudes, especially in rocky areas and around towns, and, unlike most swallows, it is often found far from water. It is 12–15 cm (4.7–5.9 in) long, with mainly brown plumage, paler-toned on the upper breast and underwing coverts, and with white "windows" on the spread tail in flight. The sexes are similar in appearance, but juveniles have pale fringes to the upperparts and flight feathers. The former northern subspecies are smaller, paler, and whiter-throated than southern African forms, and are now usually split as a separate species, the pale crag martin. The rock martin hunts along cliff faces for flying insects using a slow flight with much gliding. Its call is a soft twitter.

The crag martins are four species of small passerine birds in the genus Ptyonoprogne of the swallow family. They are the Eurasian crag martin (P. rupestris), the pale crag martin (P. obsoleta), the rock martin (P. fuligula) and the dusky crag martin (P. concolor). They are closely related to each other, and have formerly sometimes been considered to be one species. They are closely related to the Hirundo barn swallows and are placed in that genus by some authorities. These are small swallows with brown upperparts, paler underparts without a breast band, and a square tail with white patches. They can be distinguished from each other on size, the colour shade of the upperparts and underparts, and minor plumage details like throat colour. They resemble the sand martin, but are darker below, and lack a breast band.

<span class="mw-page-title-main">Purple martin</span> Species of bird

The purple martin is a passerine bird in the swallow family Hirundinidae. It is the largest swallow in North America. Despite its name, the purple martin is not truly purple.

In some light, they may even appear green in color.
