Eastern Arapahoe County and Another Prothonotary Warbler Search

October 9, 2019

Richard Stevens:

Today was a good example of Colorado's fluctuating weather.  The high was a hot 83 degrees.  Winds were 12-13 mph when I hiked around Barr Lake.  See tomorrow's forecast!

I drove around eastern Arapahoe County this morning.  At least one Eastern Bluebird continues at Richmil Ranch Open Space; no kingbirds were found.  

Misses included the Burrowing Owl along CR 18, the Sage Thrasher off CR 213 and Chestnut-collared Longspurs along CR 269.  However, I did find two Chestnut-collared Longspurs along CR 42 east of I70.  

The Burrowing Owls along CR 30 and CR 129 appear to have moved on for the year.  No Red-headed Woodpeckers found at previous locations at County Line Road and Richmil.

Another highlight was a Northern Mockingbird at last year's location along CR 42, east of CR 161.

A text message received stated that the Barr Lake State Park Prothonotary Warbler was found again today; I headed that way.  My three hour search yesterday was unsuccessful.

Today was a better day; follow the Yellow-rumped Warblers.  A flock of six or so was flying about the cottonwoods at the peninsula north of the banding station.  Other birds included two Orange-crowned Warblers, two Ruby-crowned Kinglets and the Red-eyed Vireo.  

The Prothonotary Warbler was also in the area.  Regrettably, it only allowed 3-4 second looks before disappearing back into the brush.  When last seen it was moving back toward the banding station.

A walk along the north shore of the peninsula found eighteen Killdeer to be the only shorebirds there today.

I then walked the northern shore from mile 6.0 (end of dam) to mile 5.0.  Again, no other shorebirds were encountered.  The Lesser Black-backed Gull was not relocated today.

No Short-eared Owls appeared along the DIA Owl Loop (Adams/Denver) this evening.
