BirdTrack research appeal

Many summer migrants are declining and need our help, yet important knowledge gaps remain. Bridging those gaps is a fundamental aim of our BirdTrack research project. This will deliver new insights into bird population and distribution changes, habitat use, and migration patterns across a range of species in the UK and beyond. With your support, the BirdTrack research project can unlock the insights needed to answer some of the most pressing questions about our summer migrants.

Cuckoo David

The Cuckoos are back

All of our satellite tagged Cuckoos have made it back to their breeding sites. For Vigilamus this coincided with heavy snow and a temperature of minus 5, proving too much for him to cope with, whilst for David it marked the completion of four whole migration cycles. Catch up with all of the birds here.
