One of the highlights of my recent trip to Liaoning Province was the opportunity to see so many gulls at Jinzhou Bay (we estimated over 4,000). This number must make Jinzhou Bay one of the premier gull-watching sites in northern China (if you know of a comparable site, please let me know!). The channel of running water alongside the landfill tip was a favoured haunt of Common Gulls (Larus canus) and, over the two days I spent at this site, I saw several young birds, presumably of both the subspecies found in this area – kamtschatschensis and heinei. Here are a few images and personal comments. Please let me know if you disagree with my identification or if you have more to add.
The kamtschatschensis bird, in particular, would certainly stand out if it turned up in the Western Europe!
It’s difficult to tell from these images but, in the field, the kamtschatschensis bird appeared to be stockier with a slightly longer bill.
