Black Hollow Reservoir
This large reservoir is rather far from the road, so a scope is required for good viewing of birds. Between late fall and spring, the main attraction here is usually the large flock of gulls resting from their feeding forays from the nearby Weld County Landfill. Rare gulls like Lesser Black-backed and Thayer’s are regularly part of the flock. In recent years, a pair of Bald Eagles has nested at the reservoir on the north side.
