Cuckoo class of 2016

During the last few weeks our Cuckoo team has been out fitting satellite tags to eight more Cuckoos. This will help to see how migration might differ between years. The team will also focus more closely on how the weather, in particular the Inter Tropical Convergence Zone (ITCZ) and its life giving, drought-busting rains, affects the timing of their migration. Follow them all as they head south.

Want to attract Goldfinches? Sunflower hearts are the answer!

Between November 2015 and February 2016 an amazing 5,183 households across Britain and Ireland took part in our Goldfinch Feeding Survey to help determine what it is about our gardens that Goldfinches are attracted to. A preliminary analysis of the data shows that sunflower hearts were overwhelmingly the preferred option, with nyger seed coming second. Natural foods were also taken with teasel and thistle the favourites. Thank you to everyone who took part!

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.
