First the gull. The bird in question was spotted on the banks of The Serpentine in Hyde Park, feeding with an estimated 100 - 200 other Black-headed Gulls, a couple of Herring Gulls, a dozen or so Common Gulls and 2 Lesser Black-backed Gulls.
Black-headed Gull -28P1
As you can see, it was wearing a darvic ring, 28P1, and, after a little bit of research, I managed to find out that it had been ringed in June 2015, by Reading and Berkshire Ringing Group, as a pullus at Hosehill Lake LNR, in Berkshire, 63km away. The bird had been seen there again until July 2015, and was then reported in Kensington Gardens on 8th October 2015, before moving to Hyde Park, on 6th December 2015, where it has been reported 3 times over the winter period, my record being the latest one so far.
As well as the gulls, I also managed to spot 3 new species for the year; Ring-necked Parakeet, Egyptian Goose and Cetti's Warbler. The geese were all over the park, as were the parakeets, and we were very lucky to have a couple of birds fly into a bush by the bridge, allowing me to get some nice close up photos.
Whilst watching the parakeets, we heard Cetti's Warbler calling from a small reedbed by the bridge, the same reedbed we heard them calling from in October 2015.
One final bird of note was a Black Swan that was also on The Serpentine. Not a bird to count, as it's not a British species, but interesting to see, none the less.
