Adams County Birding With Detour to Bluff Lake Nature Area, Denver County

April 27, 2015

Richard Stevens:

Rebecca Kosten and I started our birding afternoon in Adams County.  First, we scoped Barr Lake (Adams) and relocated one of the two Common Loons.

Two Ospreys are now on and around the nesting platform of the Pioneer Trail.  Let us hope they succeed in raising young!

Two Swainson's Hawks circled over the Visitor's Center.  No uncommon birds were around the feeders behind the Visitor's Center.

Next, we drove to Bluff Lake Nature Area (Denver County) and walked the 1.0 mile loop below the parking area.  The rain had stopped and winds were calm.

A Virginia Rail called from underneath the boardwalk.  A Sora called from the cattails southeast of the boardwalk.

When we walked to the northwest corner of the park, an "empidonax flycatcher" was hawking insects.  It eventually flew to the other side of the marsh, north of the main trail.  It was too wet to follow; identification remained "unknown".

Two Swainson's Hawks and a Red-tailed Hawk circled overhead.  All called constantly, allow us great comparisons of the two.

American Robins were numerous.  A Say's Phoebe caught insects as we climbed back up the stairs below the Visitor's building.

Misses: no orioles, warblers, vireos or additional flycatchers.

Back along the DIA Owl Loop, we found nine Burrowing Owls spread over three locations.  Just before sunset (time of sunset, it was cloudy, could not see the sun set), a Short-eared Owl flew back and forth west of Gun Club Road, south of 114th avenue.

This is the same field that is east of the prairie dog town along Quency Street (3.4 miles east of Tower Road & 96th Avenue).

Five Swainson's Hawks, two Red-tailed Hawks and an American Kestrel were counted along the Owl Loop.
