The first one was none other than Polish colour ringed PADZ, last seen back in August. Another adult, which I'm fairly sure is one of the ones present last weekend, was preening on the same bit of shoreline. If that wasn't enough I spotted what is most likely a fourth-winter on the water. All too soon I had to continue on my journey to Northampton, but it had been a good dinner break. I was hoping to read two new colour rings, as I'm just two short of 400 different colour ringed gulls at the site, but alas you'll have to wait for that gripping story for a little while.
|Adult Caspian Gull|
The adult above was very obliging as it lifted its wings and showed off its new P10 (longest primary feather). This nicely demonstrates one of the important features your looking for when trying to get a positive ID on an adult. Although not visible in the photo above, P5 has a dark mark on the upper side of the feather. Also its legs were only moderately long. On trait scoring, I scored it a six or possibly a seven, so it would seem to me that it is a good Caspian Gull.
|Fourth-winter or Adult Caspian Gull|
The one above was the third of the day and is possibly not a full adult. The dark markings on the bill are heavier than on typical adults, which suggests it is a fourth-winter.
It might be a bit repetitive talking about all these Caspian Gulls, but as well as writing these reports for anyone interested in gulls, I also find it a great way to keep a personal diary.
