And they're off

Five of our sateliite tagged Cuckoos have left the UK during the last few days. Thomas, a Cuckoo local to the BTO, is leading the pack and is currently in southern France. Who will be the first to cross the Sahara? Follow them all as their journeys unfold here. You can also help the project by sponsoring your favourite.

Bullfinch by Edwyn Anderton

Are you seeing Bullfinches in your garden?

Records from approximately 11,000 BTO Garden BirdWatchers indicate that Bullfinches are being seen in more gardens than ever this year! Bullfinches were seen by 19% of Garden BirdWatchers in April 2018, which is almost double the average (1995-2017) for this month. These figures follow on from a record high last winter, after a successful breeding season. Our Annual Results for 2017 show a 16% increase in the percentage of gardens reporting them compared to 2016. See the full Garden BirdWatch Annual Results.
