Orangekehlbülbül

Bestimmung

The flame-throated bulbul is about 18 cm long with an olive-green back and yellow underparts, a squarish black head without a crest, an orange-red throat. The iris is white and contrasts with the dark head. The legs are brown and the gape is yellowish-pink. The bill is dark brown to black. The plumage of young birds has not been described.

Taxonomie

The species was described by John Gould in December 1835 (but published in 1836) based on a specimen in the Zoological Society of London that had been obtained from Travancore State. Gould noted that it was very similar to Brachypus dispar (now Rubigula dispar) that had been described by Thomas Horsfield and placed the new species likewise in the genus Brachypus as B. gularis. Viscount Walden suggested that this had already been described by Jerdon as Brachypus rubineus and called the "ruby-throated bulbul" (although this name was published later). This was subsequently included as a subspecies of a larger number of similar bulbuls in the Asian region under a broadly circumscribed Pycnonotus melanicterus. With a resurgence in the application of the phylogenetic species concept, the isolated population in the Western Ghats of India was separated as the flame-throated bulbul. The crested populations in the Eastern Ghats and Himalayas that lack the red throat which were treated as subspecies flaviventris were also elevated into full species as Pycnonotus flaviventris. Pycnonotus melanicterus in this newer and narrower circumscription followed by Pamela Rasmussen in Birds of South Asia (2005) and the Handbook of the Birds of the World (2005) only included the Sri Lankan population which was referred to as the black-capped bulbul. A 2017 study noted that the Western Ghats P. gularis and Sri Lankan P. melanicterus were closely related within a clade (the age of divergence from the common ancestor of its sister clades, however, has not been estimated in the study) that includes P. montis, P. dispar, and P. flaviventris leading to a placement of these species in a new genus Rubigula.
