On Monday Sally and I made another visit to Chatham and we just had time for a few minutes bird watching on the “Waterfront”. The tide was in and a few black-headed gulls were loafing around. This juvenile black-headed gull caught my eye and Sally was able to take a short video of the bird preening. Note the colour of the bill and legs (not red) and the brown feathering in the wings that shows this is a young bird. This bird is probably a local. The Medway estuary has a large colony of black-headed gulls on Burntwick Island. Some years ago I was involved in a June count of the seabird colonies on the Medway islands. I joined the RSPB wardens on their boat and it was one of my best bird watching days ever. We found colonies of mediterranean gull, little tern, common tern, sandwich tern but, with about 6000 pairs, the black-headed gulls were by far the most numerous. Not bad for our backyard!
