Chinese Rubythroat

Calliope tschebaiewi

Il maschio, di bell'aspetto, è grigio superiormente con una gola rosso brillante, petto nero e ventre bianco. Si notino anche le sopracciglia bianche e la striscia a “baffo”, così come i pannelli e i bordi bianchi su una coda nera. La femmina è più opaca, grigio-marrone freddo superiormente con ventre e gola bianchi. Estremamente simile all'Usignolo rubino dell'Himalaya: si noti la macchiettatura grigia sui fianchi bianchi del maschio e il “baffo” bianco (vistoso nei maschi, pallido e talvolta impercettibile nelle femmine). Si riproduce in aree aperte alpine e subalpine con arbusti sparsi e massi; l'habitat preferito è mediamente più elevato e aperto rispetto a quello dell'Himalaya. Sverna nella macchia di pianura. Il canto è una serie di gorgheggi forti e ricchi, che sono mediamente più brevi e meno vari di quelli dell'Usignolo rubino dell'Himalaya.

Tassonomia

The first formal description of the Chinese rubythroat was by the Russian geographer Nikolay Przhevalsky in 1876. He introduced the current binomial name Calliope tschebaiewi. The specific epithet tschebaiewi is in honour of the Cossack Pamfili Tschebaeiv who accompanied Przevalsky on his travels. The Chinese rubythroat was subsequently considered as a subspecies of the Himalayan rubythroat (Calliope pectoralis). The species complex was given the English name "white-tailed rubythroat" and placed in the genus Luscinia. A large molecular phylogenetic study published in 2010 found that the Luscinia was not monophyletic. The genus was therefore split and several species including the white-tailed rubythroat were moved to the reinstated genus Calliope. Another study published in 2016 compared the mitochondrial DNA, vocalization and morphology of several Calliope pectoralis subspecies. Based on their results the authors recommended that C. p. tschebaiewi be promoted to species rank with the English name Chinese rubythroat. At the same time the English name "white-tailed rubythroat" was changed to Himalayan rubythroat. The species is monotypic.
