Aurora Reservoir and Return to Platte Birding Area

January 10, 2013

Richard Stevens:

Rebecca Kosten and I went to Aurora Reservoir. Unfortunately we did not arrive when they first opened (gulls tend to head over to DADS, Denver Arapahoe Disposal Site, early in the morning).

We entered from the most southeastern gate (there are three gates on the south side). By the time, we walked the couple of miles down to the shore at mile 2.5 only about 200 gulls remained. The adult Thayer's Gull was with a few Herring Gulls and many Ring-billed Gulls. We did not find the Trumpeter Swans reported yesterday.

In the afternoon, Bryan Ehlmann and I drove to the South Platte Birding Area (88th and Colorado Blvd).  Three male and two female Barrow's Goldeneyes were just south of the green and white tower (about 0.5 miles south of the parking area).

Our aim was to get better photos of the Rusty Blackbirds reported and observed last week.  We drove down to I270 at York and walked the Platte River from I270 north to I76.  At least seven Rusty Blackbirds were near the I270 Bridge.  Unfortunately, they stayed on the far side of the river; witness photos only were taken.

A Northern Shrike was on the fence at the Engineer Lake north of I76, south of Hwy 224.  We did not find any Short-eared Owls flying around the DIA Owl Loop at sunset.

It was a cloudy sunset.  Skies were cloudy, temperatures in the middle 30s and winds steady at 11 mph, gusts to 23 mph.
