Gull Search at Aurora Reservoir

February 10, 2012

Richard Stevens:

Bryan Ehlmann and I again searched for Snowy Owls south and east of Barr Lake (Adams). Again we did not find any.

We picked up Bill Cryder and hiked the 8.8 miles around Aurora Reservoir (Arapahoe). No matter what side we were on, the gulls appeared to be closer to the other.

Throughout the day, gulls fly back and forth from Aurora Reservoir to DADS (Denver Arapahoe Disposal Site). The best times to catch them resting at Aurora Reservoir seems to be 10:00am to 3:00pm.

Their favorite "resting sites" are below the east end of the dam, the swim beach and mile 2.5.

Eventually we did obtain good looks at several uncommon gulls. The adult Lesser Black-backed Gull that has appeared several times since 1/16 was at the swim beach.

An adult Mew Gull stood among many Ring-billed Gulls at mile 2.5!

Our birding day ended with a drive around the DIA Owl Loop. No Short-eared Owl sightings to report tonight.
