John Vanderpoel and I birded a number of spots in Northern Boulder County and found a few interesting birds this morning.
We started by going up to Allenspark where all three Rosy Finches were present at the Fawn Brook Inn, about 100 Gray-crowned (predominantly males and including some Hepburn’s), 10 Brown-capped and 2 Black. Several Cassin’s Finches were also present.
Returning to the plains we drove past a pond along Hygiene Road that last fall’s flood messed up. I would have identified it as just west of the St. Vrain River, but I think the “river runs through it” now. In any event we had a first winter Trumpeter Swan there. At McIntosh Lake in Longmont, there was a Merlin present in the trees along the south side and a group of gulls on the edge of the ice toward the west end that included a sharp looking adult Lesser Black-backed Gull. At Jim Hamm we found a nice variety of gulls including one California, two Thayer’s and another Lesser Black-backed.
Finally, going beyond Boulder County to Union Reservoir we found a pair of lingering Yellow-headed Blackbirds that had also been present on Thanksgiving and more gulls with a heavy proportion of Herring Gulls mixed in with the Ring-billeds.
After dropping John at his home, I continued to Valmont Reservoir where the highlight was another first winter Trumpeter Swan, or was it the same bird? Last week’s American White Pelicans were not to be found.
