Two days ago (26 November 2012), John West photographed an odd gull on the beach at Rotary Park. He sent the photos to David Vander Pluym, who immediately identified it as a juvenile Lesser Black-backed Gull!

Above are two of John’s photos of the Lesser Black-backed Gull. I have fairly limited experience with Lesser Black-backed Gull, but I do see California and Herring Gulls regularly. This bird is striking to me because the scapulars, tertials, and some of the wing coverts are solidly dark with narrow white edging. Some important ID points are the long wings, narrow white edging on the tertials not reaching the greater coverts, fairly small black bill (though it seems to be on the large side for LBBG), fairly white ground color, masked face and streaked sides, and a dark bar on the greater coverts formed by dark bases growing broader distally. In flight, it shows a black band on the tail (white bases to the outer rects) and plain dark underwing coverts.
I’ve spent the past two days running around Havasu looking for this bird, without success. However, I have seen a number of other goodies just being out and about. In the Bill Williams, David and I saw the continuing two White-winged and four Surf Scoters. At Rotary Park, we saw the two Pacific Loons which John found two days ago.

Also on Thompson Bay yesterday were two Arizona Review Species, a Black Scoter and a Red-throated Loon.

Today, I did something new, and bought a day pass to Lake Havasu State Park. I think $10 is a bit steep to walk around on otherwise abundant lakeshore, but there is usually a nice gull flock there. Not so today, but I checked the small cactus garden there, where I ran into a male Yellow-bellied Sapsucker.

Best of all these birds, though, was a White-winged Scoter on the California side of the lake. A county bird for me yesterday, and for David today. I’m planning to give the Lesser Black-backed Gull another day of searching. After all, the Glaucous Gull was notoriously difficult to find, and that bird was a cinch to pick out and ID even when it was over a mile away!
