Netherhall Herons 8th April 2022
First visit to Netherhall counted 32 nests and ringed a sample of 8 Grey Herons.
Little Egret Session Netherhall 7th May 2022
A good morning which confirmed 16 pairs of Little Egret at Netherhall. 18 young ringed was a good effort given several birds were already fairly mobile around the canopy in the trees their nests were in.
Well done to the team - photos below.
Second Netherhall visit for Herons
We did a second visit to the Heron colony at Netherhall today and ringed another 7 young. The Egrets were too small but there were seven other nests with eggs which will probably be ready towards the end of May.
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.
