The wintering raptor season has officially started! We (Boulder County Audubon Teen Naturalists) surveyed a route north of Boulder yesterday, and had an excellent morning. We found a total 32 raptors consisting of 6 different species, plus an additional four that were seen outside of the count protocol. A Rough-legged Hawk was notably special, as that species has become particularly uncommon in Boulder County in recent years. Other unusual finds were a flock of 11 pure-white domesticated doves (apparently a dwarf-sized variety of Rock Pigeon) and a very late Greater Yellowlegs at Lagerman Reservoir.
