Did you know that male Cuckoos are more faithful to breeding sites than to sites visited at other times? This is shown by work analysing the movements of BTO’s satellite-tagged birds. Read the study ➡️ bto.org/cuckoo-site-fi… #BTOCuckoos 📷Cuckoo by Edmund Fellowes/BTO

Mallard is a species that is familiar to most of us, and it can regularly be found along waterways and on water bodies. However, did you know that this species’ population has fluctuated over the years? This trend graph covers 1999–2022. Species info: bto.org/understanding-…

Drew and David W from BTO led a weekend of sessions about Waterbird ID practice, BirdTrack & Wetland Bird Survey at Idle Valley Nature Reserve and Attenborough Nature Reserve in Nottinghamshire this past weekend. Thanks so much to Nottinghamshire Wildlife Trust for allowing us to use their sites!

Our team is at the #CoimbraSeabirds conference this week sharing the Marine Evidence Review, which scoped available evidence on the movements & spatial distributions of marine birds in & around Northern Ireland waters. It was instrumental in identifying data gaps for species

Glad Breeding Bird Surveys found Idle Valley Reserve & Attenborough Reserve informative and enjoyed your time at both sites 😀🦆🦢🪶 BirdTrack Wetland Bird Survey BTO
