Big Garden Birdwatch is fun, free and for everyone. And you don’t need a garden to take part! Counting birds from your balcony, or your local park will play a vital role in helping us understand how UK birds are doing. Sign up for your free guide and let's look out for birds together on 27-29 January.

Try making a cardboard viewfinder from a recycled cereal packet to help you view and focus on nature.
