Patch Tick - Caspian Gull
4th January - my first visit to the pit this year on a very gloomy afternoon with intermittent drizzle. As usual there were 100s of Black-headed Gulls on the spit when I arrived and an increasing number of Common Gulls, estimated at 300 birds. Very few LWHG, with 7 GBB Gulls, 5 adults a 2nd winter and 1st winter, about 20 LBBs and a handful of Herrings. At 2:30pm, another scan of the gulls on the back of the spit found a rather smart, but diminutive looking 1st winter Caspian Gull - a long expected patch tick! I took a few record shots, but at distance in the gloom they were very poor.
It was quite a diminutive bird, probably a female, you can see its size next to a juvenile argentatus Herring Gull in the top photo. It showed a very white head, breast and belly, with a nice streaky shawl on the nape just reaching the sides of the breast. It was always standing below the level of a ridge, so I couldn't see its legs and then swam right behind the flock of BH and Common Gulls, so that I could only see its head sporadically. I then had to leave for the school pick-up. Just as I was leaving, an adult Yellow-legged Gull arrived.
