Hi all, I was scoping the lake from Fischer Creek Park this morning and had an interesting gull fly by at eye level. I quickly got the scope on it and followed it for a while. My conclusion was that it was either a very very light Herring Gull, or a 1st year (maybe molting into 2nd year) Thayer's Gull. I first noticed the bird when the sunlight shone through it's translucent primaries. I followed it for a while watching the effects of different angles of light both behind and on the bird. It was a gull of smaller stature. More delicate-looking that the nearby Herrings. A smaller, more delicate head shape in flight and an apparent all dark bill.The bird was mostly a fairly uniform grayish-brown mottling, esp on the chest but did show some signs of beginning to molt secondaries and some mantle feathers. Overall, it appeared to be much paler than some of the other immature Herrings. There was practically no black or brown on the under-side of the primaries (I checked when the light hit it straight on) and the upper side had limited brown rather than black. I almost called it an Iceland. I'm going through all this due to the time of year. It's a tad late for a Thayer's to be hanging around methinks. At any rate, it was definitely an interesting bird. I'm leaving the ID at probable Thayer's since I'm not used to attempting to ID 1st cycle birds in flight. They're usually sitting on ice 5 miles away.......
