Welcome to BirdFacts

BirdFacts provides key information about the UK’s birds and their changing fortunes, based on data collected by BTO and partner organisations.

BirdFacts covers all species that have been recorded in the wild in the UK, plus many non-native species that have become established here.

BTO and partner organisations monitor the populations of many of these species through core surveys. For these species, BirdFacts provides robust and up-to-date information on status, distribution, biology and trends, all thanks to data collected by volunteers.

  • For a more in-depth description of what BirdFacts covers and an explanation of the information provided, see our About BirdFacts page.
