Richard Stevens:
Rebecca Kosten and I drove over to Barr Lake (Adams County) and then along the DIA (Denver International Airport) Owl Loop.
Barr Lake was pretty quiet. The reservoir is still completely frozen over. We did count 19 Great-tailed Grackles at the first house south of the Tree Nursery at Picadilly Road and 152nd Avenue (also called Bromley Road).
We studied Horned Larks among the several thousand observed along the DIA Owl Loop. Most were along Trussville Road between 128th and 120th Avenues. We believe that we could pick out 2 or 3 subspecies (see January's "Colorado Field Notes").
No owls showed up this afternoon. We did count a Ferruginous Hawk, 2 Rough-legged Hawks, 1 Red-tailed Hawk, and 5 Northern Harriers.
