On a beach hike last winter I came upon this gull struggling with his catch. It was obviously a case of eyes bigger than stomach. I believe he was a Glaucous-winged Gull, Larus glausescens, in his winter plumage. He could also have been a Western Gull (Larus occidentalis) or even a hybrid of the two.
Did you know there are city gulls and country gulls? In the town where I grew up we had city gulls. They were noisy, aggressive, quarrelsome and frequently seen hanging out at dumpsters. Back in the 1970's when "Jonathan Livingston Seagull" was the hot book, I never understood the appeal.
Where I live now we have country gulls, quiet and peaceable. They will fly straight up into the air with a mussel and drop it onto the beach rocks to crack it open. It's almost the only noise I ever hear them make. Does that qualify as using tools?
I watched him work on that fish for about 20 minutes before moving on. He did not seem inclined to give up, so I imagine he eventually got it down. I went out to dinner that evening for fish and chips. It was something I seemed to be craving.
