Search for Area Trumpeter Swans

February 22, 2008

We went looking for the Trumpeter Swans reported this morning at Walker Lake near Franktown. While the swans were reported at 8:45am, they were not there at 10:30am. A Great Horned Owl is on a nest in the large cottonwood located east of Walker Road and just north of Hwy 86.

On our way to check Chatfield Reservoir (Jefferson/Douglas Counties) we stopped at Louviers to watch the Lewis's Woodpeckers. Three American Kestrels (2 males and a female) are also inspecting the same Ponderosa Pine Tree. Hopefully all or some will nest here.

At Chatfield Reservoir we found the lake still frozen and snow covered. Only a few Ring-billed Gulls stood on the southeast sand spit. McLellan Reservoir (north of C470 from Chatfield Reservoir) was about 2/3 frozen. No gulls were around (best to check near sunset). A few Common Goldeneyes and American Coots were all found here.

At Cherry Creek Reservoir (Arapahoe County) we found a lake 80 percent frozen. No swans, unusual gulls, or ducks. One can see Herring Gulls and a California Gull or two. We also did not find the Northern Shrike today.

At sunset we drove around the DIA Owl Loop. No Short-eared Owls came around. We counted 2 Red-tailed Hawks and a Prairie Falcon. We also checked the northern end of Buckley Road (east side of Rocky Mountain Arsenal). No unusual activity. A flock of 60 American Tree Sparrows with a dozen White-crowned Sparrows was the highlight.
