Join Gethin in this online session to find out more about the BTO's Heronries Census, and how you could take part in it.

Begining in 1928, this census is our longest-running survey. Although a simple survey, there are still many un-monitored heron colonies in Wales, and we'd really appriciate information about them. In this session, we will cover what makes the Grey Heron (and it's realtives) a wondeful bird to study, and how you can help us in monitoring this bird and become part of the Heronries Census volunteer team.

We look forward to seeing you there!
