I ran into a grouse tour this morning at Pueblo Reservoir at the Sailboard launching area, Pueblo County, and we saw a YELLOW-BILLED LOON, a Pacific and Common Loons. The Red-throated Loon was still around over the weekend too. Down at the Gravel Pit, there were hundreds of swallows of five species (couldn't find a Bank), also American Avocet and Lesser Yellowlegs, and still many ducks and gulls. I saw my first of the spring Chipping Sparrow, below Pueblo Reservoir dam this morning, as well.
Good birding,
