Southwest Denver to Aurora

October 28, 2017

Richard Stevens:

Temperatures only reached 41 degrees today.  Winds were calm to 5-6 mph.

Rebecca and I birded southwest of Denver this morning.  We scoped Marston Reservoir (which is a lake in Denver County, however surrounded by Jefferson County).  We managed to find the Red-throated Loon and at least three Common Loons.  Yesterday's Surf Scoter could not be found.

Nothing uncommon was found at Chatfield Reservoir (Jefferson/Douglas) or South Platte Park Reservoir (Arapahoe County).

We headed east through Parker (stop at the public library) and continued on to Aurora Reservoir (Arapahoe).  One or two Bonaparte's Gulls flew around with hundreds of gulls (mostly Ring-billed and some California).  No loons or scoters were found.

While Rebecca went shopping at Southland Mall, I remembered that a possible Pinyon Jay was reported near Horseshoe Park.  I walked about 3/4 mile of the trail and found two houses with feeders, however, no jays.

As I drove out of the subdivision, a Blue Jay was seen flying behind the houses along East Atlantic Circle (Arapahoe).  I stopped for a photo.  Two Common Grackles, a dozen Brewer's Blackbirds and the Blue Jay were near the bright blue house.

Then a blue jay flew to the feeders.  It was a Woodhouse's Scrub-Jay.  Photos on the recent witness photos link on the Colorado Birding Society's website:

The homeowner came out to talk and said it was the "possible Pinyon Jay" he had reported.  Unfortunately, for him, it was a scrub-jay.

His "backyard" Horseshoe Park has a nice collection of birds and mammals.  The stop ended by birding day.
