Dear Cobirders, As Nathan already posted, I had one adult male Barrow's Goldeneye at Erie Reservoir along with about half-a-dozen Common Goldeneyes, including two first Spring males. The large gathering of Gulls consisted mostly of Ring-billed Gulls with a few adult Herring and Thayer's and one adult Lesser Black-backed Gull. The number of first cycle gulls was low, I counted at least two. One of these birds was quite interesting and seemed intermediate between first-cycle Glaucous- winged and first-cycle Thayer's. Given the rarity of Glaucous-winged Gull in Colorado, it is more likely that this individual was a Thayer's with especially bleached primaries. Rounding out the interesting looking birds was a smallish, very rufous bellied Red- tailed Hawk in the parking lot (definitely a Red-tailed though). A quick stop by Thomas Reservoir revealed about 1000 more Ring-billed Gulls.
