[cobirds] DFO field trip to South Platte Park and vicinity 12/28

Today's DFO (dfobirds.org) field trip began at South Platte Reservoir, where it was near calm with a glassy, ice free reservoir surface. A highlight was a continuing Long-tailed Duck, but we did not manage to find any Black Scoter. Some far away male Ruddy Ducks tried to get away with scoter impersonations, but to no avail. I tallied at least 13 Ruddy Ducks there. The Long-tailed began over in the JeffCo pocket of the reservoir, and then disappeared from there to reappear in the southeast corner of the reservoir in Arapahoe waters.

Blackrock Lake at South Platte Park had 26 Greater Scaup, 1 Ruddy Duck, 3 Redheads (one with odd white on the nape), several Hooded Mergs, a Killdeer and more. 

The South Platte River at C470 had a Nor. Shoveler that was still a good way in eclipse (or a young male?), a Wood Duck, and very pleasant viewing of the fine details of dabblers.

A Rocky Mountain form of the Hairy Woodpecker was in the cottonwoods below the dam at Chatfield, while a Prairie Falcon and two Golden Eagles were around the dam.
