Due to three nests (one Egret and two Herons) being ready to do today we took what we thought was going to be a final trip out for 2018. A successful trip with all three nests ringed resulting in 4 more Egrets and 3 more Herons. However, it was clear that there were three Egret nests just hatched that would potenitally give 10 Egrets chicks to ring in about ten days time. It is probably going to be worth another trip out to ring these three nests as they will all be ready on the same day. So it does look like we will make five trips out this year which will result in an excellent total of Herons and Egrets for 2018.

A quick trip out to Netherhall to get Egrets was a little dissapointing with only one nest ready. Another with young that were still too small and the rest still eggs means the Egrets are clearly much later this year than usual and we will consider making one last trip to see if we can cover another nest or two.

A successful trip to the Heron island at Nethherhall with another seven Grey Herons colour ringed. Unfortunately the Egret nests which we hoped would be ready all had either young that were too small or still eggs. It looks like the cold weather has put them back a couple of weeks. Clearly the Grey Herons had already started so so pushed through the cold weather and there are several fledged nests already from this colony. We will plan a trip out at the end of next week to try and get some Egrets.

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.

If you see a bird with one of our colour rings, please use the submission form or send details (ring-code, date, location, species) to This email address is being protected from spambots. You need JavaScript enabled to view it..
