Hi all. I relocated the juvenile (??) Franklin's Gull today. It was kind enough to fly directly over me while calling, and then land ~50' away! My pics aren't all that great, but they still serve their purpose for identification and validation.
The dark gull that Norm and Gary found yesterday is still there, and I agree with Norm in his initial identification of a 1st summer Herring Gull. The reason I think this is because the head shape is smooth, whereas my Sibley's says a Western Gull's head is "rounded with peak over eye and a sloped rear crown". Plus it looks like it has a large gape. The legs (which you can't see) were pinkish/grayish.
I ALSO located what I believe to be an adult and a juvenile Western Gull! Unfortunately, I've decided I did not get a good enough look at the adult to be 100%. I did get a couple of pictures of the juvenile and am hoping someone can help me verify the identification......or tell me why my ID is incorrect.
I attached a collage of the two dark gulls. The two on the top are what I think is a Herring Gull, and the two on the bottom are what I think is a Western Gull. I saw both of these birds at the same time and within 10' of each other. They were pretty similar in size.
I still have much to learn with gull identification - especially with juvenile/subadult plumage. I realize that I may not be correct in either of my ID's, but would love to get feedback from anyone who is willing.
