16th May Netherhall final visit
Final visit to Netherhall to complete the Little Egret ringing. Two bonus Grey Heron were ringed as well. All birds processed and returned safely. One bird was found on the floor and appeard not to be in full health probably falling out of the tree before ready to fledge. We put it back up near a nest in the hope an adult may come back to feed it.
15th May 2019 Egret and Heron ringing at Walthamstow Wetlands
We made our second visit to Walthamstow Wetlands today to cover the best period for Egrets. There was a real mix of ages with some large fledged birds and still some nests with eggs. It was also noted that there was a higher than normal mortality with a lot of dead young many quite small. We assume the cold and wet weather two weekends ago probably was a big problem for these small chicks and there were at least 4 full broods with dead young around 3 to 4 days old and three dead young that were quite large and clearly had been blown out of nests or tree tops. Many of the nests that had fledged two to four young also had one dead young (probably the smallest bird in the brood) so in terms of the success for this year despite rigning 29 young Egrets today it is in reality from 30 nests quite a poor total..Huge thanks again to the London Wildlife Trust and in particular Charlie and Nadia who came out and helped ringing Egrets and climbing trees as well as sorting the boat out. Great team effort by all attending.
Walthamstow Herons 5th April 2019
We did the first survey for 2019 at Walthamstow today. 44 active nests is good. Although a proper count was not done there were approximately 37 Little Egret nests mostly with eggs so there will be some considerable ringing of these to do in a few weeks time. Due to the mild weather many birds were well advanced and many young were too big to attempt to ring. This colony was clearly much more advanced than the Netherhall colony. Eight birds were ringed of which 7 were colour ringed.
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.
