The white-backed swallow (Cheramoeca leucosterna) is a member of the swallow family Hirundinidae and is endemic to Australia. It is the only species placed in the genus Cheramoeca. As with all swallows, it is characterised by adaptation to aerial feeding. It can be identified by its white back, surrounded by black wings and tail. It has a wide distribution, from the southern part of the Australian continent, up to the Tropic of Capricorn. The white-backed swallow prefers grasslands and will create a burrow nest.

Taxonomy

The white-backed swallow was formally described in 1841 by the English ornithologist John Gould based on a specimen collected on the banks of the Namoi River in New South Wales, Australia. He coined the binomial name Hirundo leucosternus where the specific epithet is from the Ancient Greek leukosternos meaning "white-chested" (from leukos "white" and sternon meaning "breast"). [2] [3] [4] The white-backed swallow is now the only species placed in the genus Cheramoeca that was introduced 1851 in the German ornithologist Jean Cabanis. [5] The white-backed swallow is also sometimes referred to as "black-and-white swallow", "white-breasted swallow" or "white-capped swallow.". A taxonomic synonym for Cheramoeca leucosterna is Cheramoeca leucosternus. [6] The white-backed swallow is most closely related to the grey-rumped swallow (Pseudhirundo griseopyga) that is widely distributed across Africa. [7]

Birds of Australia Cheramoeca leucosterna

An adult white-backed swallow averages 15 cm long, similar in size to other swallows found within Australia. [8] The adult has a mottled grey cap above white eyebrows and a grey eye. It has a dark stripe running from the lores and across the nape of the neck. The back and most of the breast is white. The belly, wings and tail are black.

The white-backed swallow has a deeply forked tail, with curved and pointed wings. The short bill is black; the legs and feet are grey. They have a slender, streamlined body. Their eyes consist of a prominent, dark iris. The sexes have similar colouring but during adolescence the white-backed swallow has duller colours. [9]

Distribution and habitat

White-backed swallows are endemic to Australia and have a wide population distribution on the continent. They can be found from the southern latitudes of Australia and their range extends to the Tropic of Capricorn. Occasionally, after inland rainfall, white-backed swallows can extend their range to encompass the entire southern portion of Australia including the desert regions. White-backed swallows prefer open country, above open grassland and low shrubs. During the breeding season, they have a strong preference for habitats around creek beds. [10]

There is no population count, but the species is reported to be common. [11] Due to range expansion from land clearance and mining, the population is estimated to be increasing. Due to the large range and increasing population, the white-backed swallow is categorised as least concern by the IUCN.

Behaviour

White-backed swallows are insectivorous and feed in-flight on insects, like all known swallows. The composition of their diet varies by geographic region and with the time of year. They typically nest by digging a horizontal tunnel into a vertical dirt cliff. [12] Predation of swallows nests is known to occur, typically from foxes and cats. [13]

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 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.

The white-tailed swallow is a small swallow belonging to the family Hirundinidae and is endemic to Oromia, Ethiopia. It is commonly referred to as "Benson's swallow" after the ornithologist Constatine Walter Benson, who named the species. This small bird is classified as a vulnerable species by the International Union for Conservation of Nature (IUCN), as there is a progressive declination of the species which now consists of less than 10,000 adult individuals worldwide. It has a surprisingly small range for a swallow, as it is wholly dependent on a cooler "bubble" surrounding its small range, likely for proper breeding success. It is one of the most threatened bird species by climate change and a massive range reduction is projected in the future.
