BirdFacts provides up-to-date information on the status and ecology of birds in the UK, drawing on information collated by BTO and partner organisations through our citizen science surveys and research.
BirdFacts provides two ways to find the information you need
BirdFacts Places provides information for UK counties and administrative areas, detailing occurrence, seasonality and conservation status using the latest data collected by BTO volunteers.
Alternatively, BirdFacts Species covers all birds that have been recorded in the wild in the UK, plus many non-native species that have become established here. It provides robust and up-to-date information on status, distribution, biology and trends for each species.
BirdFacts Places

BTO species codes for surveys and fieldwork
Many BTO datasets use shorthand species codes, most commonly 2-letter or 5-letter codes. These can also be useful in the field when taking written notes, or to quickly enter records in the BirdTrack app.
- Species codes can be found on every BirdFacts Species page in the "Classification, names and codes" section.
- Our interactive BTO species codes tool allows you to look up all species codes for individual species.
