I'm sure this is beginning to look like its easy, but I'm really pleased that I can spot these beasts amongst the thousands of gull amassing at the site at present. These and other sightings of juvenile Caspian Gulls in England are the result of a great deal of effort over the years by the observers.
With practice the features shown by the juvenile gulls can broken down and most times an identification can be made. Its a bit like cracking a code.
I found this latest one this evening and for once it stayed around.
I'll add some more details over the next few days, but until then please enjoy watching this video.
Remember, it's best viewed by watching in 720p HD.
