The Southern Colour Ringing Group rings Grey Heron and Little Egret pulli (young in the nest) at two sites in the Lee Valley – Netherhall and Walthamstow Wetlands.
Nests are climbed up to and young removed to ring. We also fit colour rings; Heron (White with black letters and a three digit code) and Egrets (orange on the left leg and black or green on the right leg) which allows the birds to be relocated without needing to be recaptured. There are many more bird-watchers looking for colour-ringed birds, so this greatly improves our chances of understanding the movements of the birds from the Lee Valley.
