Visiting a Few Parks on the East Side of Denver

February 12, 2014

Richard Stevens:

I decided to spend the day checking on some birding locations where few birds were expected.  The temperature barely reached 40 degrees today; winds 12 mph with only a few gusts to 16 mph.

About two hours were spent walking around the relatively new Cherry Creek Valley Ecological Park in Centennial (Arapahoe County).  A Winter Wren was reported here last Saturday (2/8).

No wrens were found; none responded to my Winter Wren or Pacific Wren tapes.  A couple of Song Sparrows, Northern Flickers and 81 Mallards were just about all that was found.

Willows and a few cottonwoods line Cherry Creek as it passes through the park.  Perhaps a few interesting migrating birds will be found in spring.

My next stop was Cherry Creek Reservoir (Arapahoe).  I played Swamp Sparrow recordings at the cattail marshes near the bird observation area and the Cottonwood Creek area.  Nothing responded (well a couple of Song Sparrows appeared).

The reservoir was mostly ice and snow covered.  Only nine Ring-billed Gulls and a few dozen White-cheeked Geese were on the ice.

My finally stop was Rocky Mountain Arsenal (Adams).  Again, both Lake Ladora and Lower Derby Lake were completely ice and snow covered.  No waterfowl was found at either.

Nothing responded to recordings of Swamp Sparrows at the Mary Lake cattails or Lake Ladora cattails.

Highlights were a couple of Red-tailed Hawks and the bison.  No Long-eared Owls called at dusk thus night.
