Adult male black redstarts have slate-grey upperparts, with darker markings on their wings. The flight feathers form a white patch when the wings are closed. The rump and tail are rusty-orange and the upper tail feathers are black with rust edges.
Their underparts and face are black and they have rictal bristles surround their bills which are black, as are their eyes, legs and feet.
Female black redstarts are a duller brown-grey colour. Juvenile black redstarts are similar to females, with scaling on the throat and breast.
Black redstarts nest in holes and cavities in rocks and walls or sometimes in piles of stones on the ground. The females construct a cup-shaped nest from grass, moss, wool, hair and feathers.
Black redstarts lay 4-6 white eggs that are incubated for 12-13 days by the female alone. Chicks leave the nest after about 12-17 days but are unable to fly for several days and stay near the nest.
Black redstarts have a varied diet feeding mainly on invertebrates such as grasshoppers, flies, ants, beetles, spiders, insects, worms and snails. They will also eat fruit, berries and seeds.
Where to see them
Black redstarts can be found during breeding season in urban areas in London, Birmingham, Nottingham, Manchester and Liverpool.
During spring and autumn migration they can be found along the coast
