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.

Help us continue our vital surveys

Our surveys generate much of the data that underpin resources like BirdFacts, and help us drive positive change for the UK’s birds.

But increased pressure on funding is putting our surveys and data at risk – which is why we need your support.
