After a snowy morning with single digit temperatures, I returned to Aurora Reservoir hoping for a photo of the "Slaty-backed Gull".
Fog hung over the reservoir this afternoon reducing visibility to not much more than 100 yards. The gulls along the swim beach were much easier to see. A Glaucous Gull, several Lesser Black-backed Gulls and 3+ Thayer's Gulls were the easier gulls to Identify.
The adult Slaty-backed Gull did not show up this afternoon. Two interesting but difficult to ID gulls were in the mixed with dozens of Ring-billed Gulls and few Herring Gulls and one California Gull.
A possible Glaucous-winged Gull hunkered down among the hundreds of gulls. Another strange looking Gull was "called" a possible 1st cycle Slaty-backed Gull by Nick Komar.
I digiscoped the line of gulls for future inspection and headed to Quincy Reservoir as the gulls all took off around sunset and flew west. I was hoping to discover where they spent the night. It was not Quincy Reservoir; the only birds there were White-cheeked Geese and American Coots.
It was too dark to check nearby Cherry Creek Reservoir; perhaps that is where they roost for the night?
