As I expected, this was a bit tougher quiz than our last one. The answers included 5 species of gull, a Northern Fulmar and 1 vote for “Seagull – our state bird”. Fulmars are not on our Utah checklist and thus not even an option for the quiz. I guess the same goes for Seagull, although I did like that answer.
The 5 gull species were: Little Gull, Glaucous Gull, Glaucous-winged Gull, Thayer’s Gull, and Iceland Gull. Little Gull is the only easy one to rule out. They always show some sort of gray or black pattern on the back and head. The other 4 choices aren’t so easy. Gulls are always tough, and this quiz is even tougher because it doesn’t show the head or bill. All that leaves us is the color and pattern. Our bird doesn’t have a gray mantle, so we know it is not an adult bird. The color is light and uniform, not showing any real contrast on the wing tips or tail. It is a good idea to look at more than 1 field guide since they are always a bit different, but for this bird I like the flight photos of juvenile gulls in the National Geographic. Compare that page with the photo quiz bird. If our quiz bird was a juvenile Thayer’s Gull , it would show a darker tail and probably darker wing tips as well. It would also probably have a bit more dark/light mottling as well. A juvenile Glaucous would have whiter wing tips and appear whiter overall. So would an Iceland Gull. I admit that I don’t have much experience with Iceland Gulls, but I don’t think an Iceland Gull would have as chunky of a body as this gull either. That leaves us with a Glaucous-winged Gull – the answer to this quiz.
