People are being encouraged to give a bird a home during National Nest Box Week, which runs from 14 February to the 21 February.
The British Trust for Ornithology, which organises the week, wants the public to compensate for a loss in natural nest sites by putting up nest boxes in their gardens.
Though any box is a welcome addition for the bird community, dedicated swift nest boxes are being promoted this year in an attempt to house the species as they return to Britain for the summer.
Various events, from box building to nest trails, are taking place around the country in support of the cause. To find out more about which birds use which boxes and for instructions on making a box visit www.bto.org
