Collalba Capirotada

Identificación

The capped wheatear is 17–18 cm long and weighs 32 g. Its legs and pointed bill are black. This common species is striking and unmistakable in appearance. The adult has a black cap, cheeks and breast band, and white eye stripe and throat. The rest of the underparts are white with buff on the flanks and lower belly. Like other wheatears, it has a distinctive tail pattern with a black feathers on the base and centre of the tail forming an inverted T against the otherwise white rump. The juvenile has a brown cap and cheeks, and the breast band is weak and diffuse. However, the breast band, larger size, and white at the base of the outer tail feathers distinguish it from the migrant northern wheatear, which is rare over most of the capped wheatear's range.

Taxonomía

The capped 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 wagtails in the genus Motacilla and coined the binomial name Motacilla pileata. The specific epithet is from Latin pileatus meaning "-capped". Gmelin based his account on the "Black-hooded wheat-ear" that had been described in 1783 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. Latham's specimen had been collected near the Cape of Good Hope in South Africa. The capped wheatear is now placed in the genus Oenanthe that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot.<p>Three subspecies are recognised:
