A Great Birding Day in Boulder County

October 27, 2017

Richard Stevens:

Terry Michaels and I birded in Boulder County today.  One of our target birds were the Tundra Swans reported yesterday at Sombrero Marsh.

We did not find any Tundra Swan in spite of checking Sombrero Marsh, Baseline Reservoir, Boulder Reservoir, Valmont Reservoir, Walden Ponds, Sawhill Ponds, White Ranch Pond, Teller Lakes, Prince Lake #2, Erie Reservoir, Lagerman Reservoir, and Terry Lake.

We also stopped at Teller Lakes #5 where a Golden-crowned Sparrow has wintered the past five winters.  No sparrows were around the parking area or lake today.

A fortunate stop at the Public Library to pick up our emails turned out great.  We read that Nick Moore had found a Yellow-throated Warbler at Kittredge Lake.  The CU Campus was just down the road so we headed that way.

We circled around the lake and found two Yellow-rumped Warblers and the Yellow-throated Warbler in an oak tree at the northeast corner of the eastern lake!  The warbler stayed high in the oak tree, no photo opportunity; what a great ending to the "daylight" part of our birding day.

After dinner, we continued west to do some owling.  The evening was quite pleasant with little winds.  We enjoyed the hike around Gross Reservoir and added a Northern Pygmy-Owl to our day list!  Misses: no Common Poorwills could be found, not that they were expected this late in the fall.

A second Northern Pygmy-Owl was found near Gross Dam Road and Coal Creek Canyon Road (just north of the Boulder/Jefferson County line).

Yet a third Northern Pygmy-Owl was found after midnight at White Ranch Open Space (Jefferson).

No evidence of Northern Saw-whet Owls or Flammulated Owls was found.  Northern Saw-whet Owls should still be around, not so much for Flammulated Owls.
