[cobirds] Weld and Broomfield counties today

I spent the better part of the day wandering easy of Boulder today. Nothing too exciting.
Union Res was almost totally frozen a small hole held a Red-breasted Merganser. A Swamp Sparrow was in the large marsh area.
The ponds in front of St. Vrain State Park were mostly frozen nothing unusual.
The Firestone gravel pits were all frozen.
At Frederick Reservoir there were an amazing number of geese certainly in the thousands almost all richardson's cacklers with four Snow and one Ross's Goose. This is a great place to see the variation in white-cheeked geese.
Finally I went to see the gulls at Anthem Ranch in Broomfield which was mostly ice free. Diversity was low but there were hundreds of gulls. A lingering California Gull, around ten Herring and about four Thayer's Gulls they were moving about so numbers were very frustrating. Hopefully more gulls will start coming in from up north.
Good birding!
