Scoping from the east end of the lake by the boathouse, I quickly found two Barrow's like birds. The first was Bill's apparently pure adult male BARROW'S GOLDENEYE just off the golf course. This bird has a very long facial crescent that goes above the eye to a sharp point. Head shape is typical for the species with a shaggy mane and a steep forehead; the head gloss is the typical purple iridescence as well. The back is mostly black, neatly outlining a narrow row of white scapular patches, the first two of which blend together somewhat. The bird clearly shows a black "spur" coming down from the shoulder. The extent of this appears somewhat variable depending on the bird's posture, but it can be quite marked, even extending all the way to the water line. The other bird is a Barrow's-like BARROW'S x COMMON GOLDENEYE hybrid. It differs from the above bird in the following respects: 1) The facial crescent, although tear-dropped, does not extend well above the eye. 2) Although the head shows a shaggy mane with purple gloss, the forehead is not as steep as that of a Barrow's, resembling more that of a Common Goldeneye. 3) Although the back was very dark, immediately suggesting Barrow's, the white scapular spots were slightly larger and perhaps slightly more run together at the front end (three of the spots?). Easier to judge, in addition to these spots a narrow white line surrounded in black runs along the lower edge of the white scapular marks (crisper on the right side of the bird when I saw it). 4) There is no spur at the shoulder, just a right angle of black. This can be hard to judge as the bird was actively foraging and therefore sitting low in the water so that this area was often submerged. However, it could be seen when the bird jumped at the start of a dive and when it was swimming in a more relaxed manner with a female COMMON GOLDENEYE. Other birds at the lake included 8 SURF SCOTERS, a HORNED GREBE, many GLAUCOUS-WINGED GULLS (adults, first-winters, and one second-winter bird), and three adult WESTERN x GLAUCOUS-WINGED GULL hybrids.
