About 26 centimetres long, the male blackbird is all black with a yellow bill and eye ring, while the female is sooty brown with slightly lighter brownish throat and mottling on the breast, and a dark bill. The young blackbird is similar to the female, but with small pale spots on its upper parts. The blackbird resembles the starling from a distance, but it has a longer tail and makes quick, two-footed bounds. It typically also walks a few steps before standing dead still for a few seconds, then taking a few more steps.
Northern populations are migratory, wintering mainly in Western Europe. The blackbird breeds commonly in woodlands, parks and gardens. It can be found throughout Europe.
The blackbird nests in bushes and trellises. It feeds on earthworms, insects and berries.
