BLACK
REDSTART... (Phoenicurus ochruros) is a small passerine
bird in the redstart genus Phoenicurus. Like its relatives, it was formerly
classed as a member of the Thrush family (Turdidae), but is now known to be an
Old World flycatcher (Muscicapidae).
This species belongs to a Eurasian clade which also includes the Daurian Redstart, Hodgson's Redstart, the White-winged Redstart, and maybe the Ala Shan Redstart. The present species' ancestors diverged from about 3 mya (Late Pliocene) onwards and spread throughout much of Eurasia from 1.5 mya onward. It is not very closely related to the Common Redstart. As these are separated by different behaviour and ecological requirements and have not evolved fertilisation barriers, the two European species can nonetheless produce apparently fertile and viable hybrids.
There are a number of subspecies which differ mainly in underpart colours of the adult males; different authorities accept between five and seven subspecies. They can be separated into three major groups, according to morphology, biogeography, and mtDNA cytochrome b sequence data.
The Black Redstart is 13–14.5 cm in length and 12–20 g in weight, similar to the Common Redstart. It is a widespread breeder in south and central Europe and Asia and northwest Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. It is resident in the milder parts of its range, but northeastern birds migrate to winter in southern and western Europe and Asia, and north Africa. It nests in crevices or holes in buildings.[INFO:WIKIPEDIA]
