Rocky Mountain Arsenal & Aurora Reservoir

December 6, 2016

Richard Stevens:

My birding day started when while out doing chores I passed Rocky Mountain Arsenal (Adams).  A Swamp Sparrow was along the south side of Marys Lake.  There is no way to tell if it is the same one from 11/10. 

Both Lake Ladora and Lower Derby Lake were mostly ice covered.  Winds were 14 mph, gusts to 20 mph; temperatures were around 23 degrees.

Next, I drove to Aurora Reservoir (Arapahoe) with the plan to scope the lake from the swim beach parking area and then go home.  It was just too cold for much more.

The Long-tailed Duck was still off to the east, although it was farther away (400 yards+) then yesterday.  The White-winged Scoters were still 50-100 yards off the cove at mile 1.5.

With a predicted snowstorm (2-5 inches) expected tomorrow, I changed my mind and drove around to the southeastern entrance, then hiked the 1.2 miles to the bench at mile 2.5.

The Black Scoter and two Surf Scoters were again near the mouth of Lone Tree Cove!  Two Common Loons were just west of mile 4.0.
