Back at Cherry Creek Reservoir Again

November 22, 2009

Richard Stevens:

With no reason to see the second half of the Broncos game (Final: Chargers 32, Denver 3) I went back to Cherry Creek Reservoir (Arapahoe County).

On the way, I stopped at Barr Lake (Adams) and found the Common Loons off boat ramp. Great-tailed Grackles are still massing south of the Tree Nursery at 152nd and Picadilly Road.

At Cherry Creek Reservoir, water level was a little lower than yesterday. Three plus Bonaparte's Gulls were flying around the northeast corner. A little of the southeastern sand spit was exposed. One hundred and fifty plus gulls (mostly Ring-billed and a few California; no Herring Gull) stood among 10 American White Pelicans and half a dozen White-cheeked Geese.

From the bird platform, I could see two Common Loons. The Virginia Rail came by but was not scolding today. A Marsh Wren came out of the cattails in response to a Swamp Sparrow recording.

I sat at the southwest marina at sunset; only 300+ Ring-billed Gulls stood on the surrounding floating telephone poles at 4:38 pm. Ten minutes later an adult Herring Gull flew in and a little later the adult Lesser Black-backed Gull. It had not shown up Saturday, but was there Friday. This could be the same Lesser Black-backed Gull observed by Jerry Petrosky at Aurora Reservoir this morning.

Again, the previously reported male Barrow's Goldeneye was not found. A surprising 27 Pied-billed Grebes were counted between the southeast corner, the bird platform and the southwest marina.

Dozens of Western Grebes swam east of the Dam's Tower. I could not pick out a Clark's Grebe or Red-necked Grebe among them.
