The red-collared widowbird (Euplectes ardens) is a species of bird in the family Ploceidae. Red-collared widowbirds are found in grasslands and bush clearings in Eastern and Southern Africa. They are known for their long tails and brilliant red badges, both which act as sexual ornaments. They are often associated with other widowbird and bishop species. They are polygynous, where males acquisition of territory is an important determinant in their access to mates. Red-collared widowbirds have a wide range and there is little concern in terms of conservation status.
When Dutch naturalist Pieter Boddaert first described the red-collared widowbird from a South African specimen in 1783, he named it Fringilla ardens, assigning it to a genus of Old World finches. In 1829, William John Swainson created Euplectes, and moved the widowbirds and bishops from Fringilla into this new genus. Traditionally, Euplectes is thought to contain two clades, with the bishops in one clade and the widowbirds in another. However, molecular evidence suggests that the red-collared widowbird is actually a long-tailed bishop rather than a true widowbird. In captivity, they have been successfully bred with southern red bishop, yellow-mantled widowbird, fan-tailed widowbird, and black-winged red bishop.
There are three recognized subspecies:
The latter two taxa were split in 2017 as the red-cowled widowbird (Euplectes laticauda) by del Hoyo and Collar.
Similar to other widowbirds, male red-collared widowbirds have both seasonal and sexual dimorphism. Males are about 25 cm (9.8 in) in length while females are only 13 centimeters. A similar trend is seen with weight, where males range from 20 to 26 g (0.71 to 0.92 oz) and females are only between 16 and 22 grams. During non-breeding seasons, the male plumage is brown, while in breeding season, October to April, they have black plumage with a long tail, approximately 22 cm, and crescent –shaped carotenoid based chest patch. There is significant variation in brightness, hue, and chroma of the carotenoid badges. In contrast, females and subadults, like nonbreeding males, are streaky dull brown with a short tail, approximately 4 cm. Nonbreeding males, however, retain their black tails, while females and subadults' tails are dark-brown.
