Search for Swamp Sparrows

March 13, 2016

Richard Stevens:

Another nice Colorado winter day.  Temperatures reached the middle 60s; winds were less than 6 mph.

I went out looking for Swamp Sparrows at various cattail marshes this afternoon.  None was at Cherry Creek Reservoir (Arapahoe), Barr Lake (Adams) and Aurora Reservoir (Arapahoe). 

Success finally when I stopped at Beebe Seep Canal (Adams).  A Swamp Sparrow was singing when I stopped at the canal located along 152nd avenue, just east of Picadilly Road.  It was about 20 yards north of 152nd avenue.  The sparrow flew up once and landed in the cattails just west of the first bushed north of 152nd and east of the canal.  I could not get it to fly up a second time.

A Wilson's Snipe flew up from south of 152nd Avenue.  It walked out of the weeds and confirmed that it was not an American Woodcock.

At Cherry Creek Reservoir, Song Sparrows and Lincoln's Sparrow were seen from the bridge over the canal at the Cottonwood Creek Wetlands. 

Another Lincoln's Sparrow was seen in the cattails at mile 0.5 at Aurora Reservoir. A couple of Song Sparrows and a small flock of five American Tree Sparrows were in the same area.

The Burrowing Owl was again seen inside the chain link fence at Trussville Street and 114th Avenue (Denver). 

No Short-eared Owls appeared tonight along the DIA Owl Loop.  No additional Burrowing Owls were found around the various prairie dog villages on the Loop.

I did not find the yesterday's reported Swamp Sparrow at 112th avenue.
