[cobirds] Arapahoe Co.: Mew Gull—South Platte Reservoir

Hi all,

Around 5:30pm, just as light was really starting to go, I found an Adult Mew Gull bathing in the open water. The bird was slightly smaller with a rounder head and slightly darker back compared to the Ring-billed Gulls, and the bill was noticeably thinner and appeared unmarked.

1 Glaucous Gull and 2 Lesser Black-backed Gulls were around, as well.
