Heron colour-ringing

Last night we started a new colour-ringing project - grey herons on the Ythan. We are hoping to find out how long our birds use the estuary for as well as further movements.
Last night we ringed 13 chicks, with lots more to go back for in the next week. Colours are grey, brown, black, lime and yellow so far; with one or two rings.
