Nest Box Challenge

To get the most out of putting up your nest box, take part in Nest Box Challenge and help us to monitor the breeding success of birds in Britain’s green spaces. To take part, simply register your nest box online and then give us regular updates on whether it is used, what birds are using it, and the progress of any nests.

And if you have any other nests in your garden, we want to know about those too! The Blackbird nest in your privet hedge and the Collared Dove nest on your satellite dish can both be monitored for Nest Box Challenge.

Last year, over 3,500 boxes were monitored in 1,300 gardens across the UK–join the nest monitoring community by registering today!

NBC checklist

  • Register your box as soon as possible – you don’t have to wait until a bird uses it.
  • Tell us if your nest box is empty. We really want to know about boxes that aren’t used as well as those that are so we can work out how often they are occupied.
  • Monitor your boxes at regular intervals throughout the season and record what happens. The most detailed information is collected by looking inside, but if you don’t want to or can’t look inside your box/nest, you can still collect useful information.
  • Keep checking your box until the end of August – most nest box species don’t fledge chicks until the beginning of June, and some species may have a second brood in the summer.
