Nest Box Challenge
Nest Box Challenge is organised by the BTO. Since the project was launched in 2007, 20,000 nest boxes have been registered across the UK.
Putting up your nest box is really only half the fun – to get the most out of it, take up the Nest Box Challenge and help us to monitor the breeding success of birds in Britain’s green spaces.
All you need to do is register your nest box and report on the contents, whether it’s used or not, at regular intervals through the spring and summer.
