Monachella nera

Oenanthe leucura

Un grande e scuro culbianco distintivo con un becco robusto. I maschi sono in gran parte tutti neri tranne la coda, il groppone e il sottocoda bianchi. La coda ha un centro nero e una banda terminale. Le femmine sono simili, ma più marroni. Normalmente si incontra mentre foraggia a terra in aree rocciose con pendii ripidi. Timido e tipicamente vola in salita quando spaventato. Il canto è un piacevole gorgheggio, a volte con un elemento ronzante o trillato. I richiami includono un fischio dolce "eee eee".

Identificazione

This large 16–18 cm long wheatear. The male of this species is all black except a white rump and mainly white tail. The female is similar, but dark brown rather than black. It has a loud thrush-like song.<p>The similar white-crowned wheatear (Oenanthe leucopyga) also breeds in the African part of the black wheatear's range, but the black wheatear has a black inverted "T" on its white tail, whereas white-crowned has only a black centre to its tail. The black wheatear never has a white crown, but young white-crowned wheatears also lack this feature.

Tassonomia

The black wheatear was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the thrushes in the genus Turdus, coined the binomial name Turdus leucurus and specified the locality as Gibraltar. The specific epithet is from Ancient Greek leukouros meaning "white-tailed". Gmelin based his account on the "White-tailed thrush" that had been described and illustrated in 1783 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham had examined a specimen in the Leverian Museum in London. The black wheatear is now placed in the genus Oenanthe that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot.<p>Two subspecies are recognised:
