Now that the trees are bare, birds' nests from last summer become visible in the hedges and trees.
Most are deserted and crumbling away, and the parents and young that used them are roosting at night in dense bushes or reed beds. However, wrens may crowd into one of their old domed nests on a cold winter's night, and birds such as blue tits and great tits may roost in the hole they nested in.
Rooks come back to their communal rookeries in the spring, and repair their nests of mud and twigs to use them again. They also visit them regularly in winter. Carrion crows sometimes sit beside their similar but solitary nests in the treetops.
The most dramatic nests are magpies' nests
