The featured article for Thursday, 30 January 2020 is Golden swallow.
The golden swallow (Tachycineta euchrysea) is a passerine in the swallow family, Hirundinidae. Two subspecies are recognised, the Jamaican T. e. euchrysea and T. e. sclateri of Hispaniola (Haiti and the Dominican Republic). It usually inhabits the hills on the interior of islands, preferring open country. Currently, this swallow is restricted to isolated montane forests that primarily consist of the Hispaniolan pine. This species is considered to be a vulnerable species by the International Union for Conservation of Nature (IUCN), although the nominate subspecies, T. e. euchrysea, is likely extinct. The exact cause of extinction is unknown, but likely factors include predation by mammals and habitat loss, although the habitat loss theory is not supported by very much evidence. The last sighting of the nominate subspecies was in Hardwar Gap (located on the boundary between Saint Andrew and Portland parishes), with three birds being seen on 8 June 1989.
A relatively small swallow, the nominate subspecies has bronze upperparts and bronze sides of the head. The ears and lores are duller and the forehead area is more green than bronze. The shoulders, back, rump, and uppertail-coverts are, on the other hand, a coppery-bronze colour. The lesser and median coverts are more coppery, with the greater and primary-wing-coverts being more of a dusky green. The primaries, secondaries, and tail are a dusky bronze-green. The underparts are mostly white. The legs, feet, and irides are dark brown, and the bill is black. The female is similar but with its breast, and occasionally throat and undertail-coverts, being mottled grey-brown. The juvenile is also mottled-grey brown, in addition to it being duller overall. The extant subspecies, T. e. sclateri, is primarily differentiated by its more deeply forked tail, blue-green forehead and uppertail-coverts, and blue-black wings and tail.
In Hispaniola, this swallow breeds from April to July, where it lays a clutch consisting of two to four white eggs. It formerly bred from June to July in Jamaica. The eggs are laid in a cup nest that is mainly found in Hispaniolan pine. It also nests in caves, under the eaves of houses, in burned stands, and in nest boxes. This swallow is an aerial insectivore, foraging for insects at heights that are usually under 20 m (66 ft), and very rarely at heights over 30 m (98 ft). When foraging, it is known to explore most habitats except forests.
