John Martin Reservoir is huge, and birds seen one day may be impossible to find in the same spot even hours later. I've been able to look at parts of the reservoir on January 7th and 8th.
On January 7th, I observed both an adult Lesser Black-backed Gull and adult Mew Gull on the ice shelf on the western edge of the reservoir. Neither were seen today, but an adult California Gull and a first-cycle Glaucous Gull took their places. Two Long-tailed Ducks were seen from the dam, just beyond the ice shelf on the 7th. With literally tens of thousands of Snow and Ross' Geese, mergansers and goldeneyes, it is not easy to find them.
Today, near the junctions of the Arkansas and Purgatoire Rivers, I located one female Northern Cardinal, two Harris' Sparrows, and three Lesser Goldfinches. This seems to be an extraordinary year for Lesser Goldfinches wintering in SE Colorado, with birds seen on both the John Martin Reservoir and Rocky Ford CBC's. Today's Lesser Goldfinches were a couple of miles from where they were found on the CBC, indicating that they may actually be far more widespread this winter.
