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.
