The black redstart (Phoenicurus ochruros) is also known as the Black Redtail. It was formerly considered a Thrush, but is now classified as an Old World Flycatcher. Black Redstart lives in rocky hilly or mountainous areas, towns and villages. It has adapted to live in industrial and urban centres, and may nest in railway stations, factories, buildings, quarries and cliffs. In the summer, the male bird's plumage is quite striking: grey-black upperparts, sooty black breast and face, a bold white wing patch, and a rusty-red rump and tail. There are several sub-species, which can look very different - for example, the eastern sub-species has an orange/red underbelly. The female is duller, brown-grey with rust-red rump and tail. In the winter the male looks like the female.
