More birds are nesting in our gardens than ever before. If you’re lucky enough to have any avian residents in your garden, here’s how you can learn who lives where.

With spring here, watch out for birds carrying nesting material or look out for abandoned nests in the autumn.

But remember not to disturb nesting birds – it is an offence under the Wildlife & Countryside Act 1981, and a licence is needed for photography.

NB All nest measurements refer to the size of the nest cup.
