Rocky Mountain Arsenal to DIA Owl Loop

February 21, 2019

Richard Stevens:

High temperature was 32 degrees today.  Winds were faster than yesterday at 12-13 mph with gusts to 18 mph.

I wanted to exercise my legs in preparation of our soon Grouse Trip (2000+ miles driving in seven days).  

To cover two birds, I went to Rocky Mountain Arsenal (Adams) to look for the Lesser Black-backed Gull reported several days ago and a report of a Swan on Havana Ponds (Rocky Mountain Arsenal).

No gulls were found on Lake Ladora or Lower Derby Lake.  Ladora was completely ice/snow covered and Lower Derby had a small open water area.  White-cheeked Geese and a couple of Common Goldeneyes swam on Lower Derby.

I then hiked to Havana Ponds (approximately 2 miles round trip).  They were completely ice covered.  A large white buoy was stuck in the ice.  From 56th avenue about 0.5 miles to the south, I suppose the buoy could have looked like a swan.

A drive around the DIA Owl Loop 30 minutes before sunset found a flock of fourteen Horned Larks.  No owls appeared this evening.  

Burrowing Owls may show up at any time.  Short-eared Owls should be performing their mating flights soon.
