Fire leaf (Lophura ignita) - a species of large bird from the family of hen family (Phasianidae). It occurs in two subspecies in Borneo and the island of Bangka off the coast of Sumatra. In Sumatra itself, in its southeastern part, there are hybrids with red-backed clusters (L. rufa), formerly considered a fire subspecies. The species is in danger of extinction.
The species was first described by George Shaw in 1798. The holotype came from southern Borneo (between Pontianak and Banjarmasin), Java was incorrectly indicated. The author gave the new species the name Phasianus ignitus.
Currently (2021) the International Ornithological Committee is placing a fiery wrist in the genus Lophura. It distinguishes 4 subspecies, similar to the authors of Howard and Moore Complete Checklist ... (2014) and HBW (1992), but their number is disputed. There were 3 on the Clements Checklist of Birds of the World (August 2019), and on the list of birds of the world prepared in collaboration with BirdLife International and HBW authors (5th online version: December 2020) - 2. Both latter authorities do not recognize L. and. macartneyi (Temminck, 1813). Representatives of this subspecies differ significantly from each other and can be hybrids of fire bunches of the nominative subspecies and red-backed bunches (Lophura rufa). The latter were previously considered a subspecies of the fiery wrist, but some modern authors elevate them to the rank of a species. In this approach, there are two subspecies:
L. i. Nobilis (Sclater, 1863)
L. i. Ignita (Shaw, 1798) Collar and Prys-Jones (2014) confirmed the assumptions that had appeared since the end of the 19th century and recognized L. i. Macartneyi as a hybrid. Among the 12 museum specimens they saw, attributed to this form, there were no two with matching plumage. One had an appearance more or less in between the fire and red back clusters, but most had less balanced features. Since there are no phenotypic features which distinguish this form and allow it to be certainly identified, it should not be considered as representing any taxa. According to the authors, the lack of a transition between L. rufa and L. ignita, which is indicated by the varied appearance of hybrids, confirms the legitimacy of considering each of these clusters as a separate species.
The cladogram of the genus Lophura according to Stein et al. Is presented below. (2015):
He points out that the fire bunting is a sister species to the Siamese bunny (L. diardi), and the two species together constitute a sister species to the black bunny (L. inornata). L. inornata and L. ignita + L development lines. diardi diverged about 4.86 million years ago, and the fire and Siamese bunches separated nearly 3.0 million years ago. The mutual relations of these three species are also presented by Jetz et al. (2012), the moment when L. inornata and L. ignita + L lines diverged. diardi was estimated at 2.41 million years ago, and L. ignita and L. diardi at 1.55 million years ago. Hosner et al. (2020) obtained slightly different results depending on the method of phylogeny reconstruction, but according to them either the fire and the black bunches are a sister group to the Siamese, or the fire and Siamese bunches are a sister group to the black one.
It is not entirely certain how populations of firebands and redbacked bunches have been able to come into contact with each other in southeastern Sumatra where hybrids are present. Although Sumatra and Borneo share history biogeographically and most recently split between 10,000 and 12,000 years ago, differences in fauna developed during much earlier periods of isolation from each other. On Bangka, off the southeast coast of Sumatra, there are bunches of fire L. and. Ignita. One of the hypotheses says that they were introduced there by travelers from Borneo, and then they got to Sumatra
