A quick response from the ringer responsible:
Many thanks for your sightings of Mute Swan RED 597 which has come to me as ringer of the bird in question.
RED 597 (ring X6128) was ringed as a one year old male at bank island, part of the Lower Derwent Valley NNR, near Wheldrake, York, on 20th August 2012 and was still present on 12th September. (One of 18 caught that day). Your is the first resightings.
New holland is a site where we have had a number of movements concerning our ringed birds from LDV. Most of the birds which have been seen here have either also been to or subsequently turn up at Hornsea Mere (usually in the summer for the moult) so it will be interesting to see if he also follows this route.
It is however interesting that this bird was from the first moulting birds ever to use the LDV - probably staying due to the very wet conditions - but providing an insight to this behaviour should this trend continue. It also shows the turn over of birds in and around the LDV. Despite holding up to 130 in the valley at the moment, some of our summer herd birds like this one have clearly moved out whilst others have settled locally and presumably other birds from since arrived.
Hope that helps – write up and photo’s of his capture are on here
