We actually had 4 species of Picidae in Douglas County today, near Hwy 67 and Rampart Range Road-- Williamson's and Red-Naped Sapsuckers, and very active nest holes of both Three-toed and Hairy Woodpeckers. Lots of activity, and great fun to watch.
Also all three species of Nuthatch, Empidonax flycatchers (we went looking for the Hammond's, but believe these were Willow), Western Bluebirds, many House Wrens, many Broad-tailed Hummingbirds, Pine Siskins, Gray-headed Juncos, Robins, Ravens, Mtn. Chickadees, etc.
