Walk at Cherry Creek Reservoir

April 10, 2017

Richard Stevens:

Temperatures reached 63 degrees in Aurora today.  Winds were 12 mph with gusts to 29 mph.

After riding in a car last week for 2160 miles, I needed a long walk today.  I chose Cherry Creek Reservoir (Arapahoe) and walked from the Cottonwood Creek wetlands restroom parking area to the Mountain Loop and back.

Target bird, the Eastern Bluebirds reported a few days ago were not found.  No Western Kingbirds or American Tree Sparrows were found either.

Highlights came during the walk from the Prairie Loop parking area along Cottonwood Creek back to the wetlands pond.

First a Swamp Sparrow was found twenty feet south of the cottonwood tree with the nest in it (south of the paved path with now closed sign, footbridge has been washed out for months).

Continuing south, a Stub-tailed Wren popped out of the brush.  The location was halfway between the end of the strip of willows south of above paved path and the footbridge along the cement bike path.  It was just south of the skinny 10 foot tree.

I first played a Pacific Wren recording and received no response.  Then I waited five minutes and played a Winter Wren recording.  The Winter Wren popped out of the willows from the third time.

The many swallows flying over the Cottonwood Creek Pond and toward the Bellvue Wetlands Pond include two Northern Rough-winged, two Cliff, twenty four Barn, twelve Tree and at least one Violet-green.

No American Tree Sparrows were found today; two Chipping Sparrows were observed around the Lake Loop.

After the long walk, I drove to the eastern boat ramp upper parking area to rest.  There was motion under the bushes southeast of the restroom as I stopped the car. 

When I observed the Fox Sparrow days ago, the same thing occurred.  Motion was spotted and after an hour, the Fox Sparrow emerged from under the bushes.  After about 10 minutes, a male Ring-necked Pheasant came out.  No Fox Sparrow was appeared during my hour stay.
