Trip to Guanella Pass

June 17, 2017

Richard Stevens:

Rob Berg and I drove up to Guanella Pass from the Grant side (hwy 285).  Besides some nice bird, we missed the heat down in Denver.  The high up there was 68 degrees.  Winds were 12-13 mph with gusts to 22 mph.

Eventually we found a pair of White-tailed Ptarmigan by listening for their soft calls.  The birds were 20 yards or so southeast (uphill) of the Rosalie and 603 trails.

Many White-crowned Sparrows fluttered about the short willows.  We were quite sure that at least two "Timberline" Brewer's Sparrows were found (photographed and recorded audio).

Other birds found included a Slate-colored Fox Sparrow, American Pipits, Wilson's Warbler (kind of high for it?), Prairie Falcon (zoomed by), and Red-tailed Hawk.

At the Guanella Pass Campgrounds, we added a MacGillivray's Warbler, two Pine Grosbeaks and an American Three-toed Woodpecker to our day list.

Unfortunately, we had to return to the heat in Denver.
