This morning three Red-tailed Hawks were active in the Bear Creek Greenbelt, west of Estes.  It was a gray, overcast day with temps just below 40 degrees, and a little breeze.

I was able to photograph two of the hawks–neither of them part of the resident pair.

Here’s one of them:

This morning I joined the walk that Joey Kellner leads monthly at Chatfield State Park.  Townsend’s Solitaires were conspicuous.  Here’s one after juniper berries:

Joey delighted us all by spotting a Chestnut-sided Warbler.  Photographing it was challenging:

Most of the leaves have now fallen from the trees in the Bear Creek Greenbelt, which opens up possibilities to see more birds.  Here’s a Red-tailed Hawk that is neither the resident female nor male.  It’s possible it could be their sole offspring this year.  The last time I saw this year’s offspring, it looked like this:  Red-tailed Hawk Nestling on May 20, 2021

Today on a lunch walk in the Bear Creek Greenbelt I found a collection of a dozen waterfowl:

Ten Ring-necked Ducks, one Redhead, and one Mallard

The two female Ring-necked Ducks:

After work I led my better half to the part of Bear Creek where I’d seen the American Dipper earlier.  We couldn’t find it from the south bank, but a while later when we walking along the north bank, I found it again:

A deer was heading west along the south bank:

In the last week I saw in the Bear Creek Greenbelt my first-of-season Yellow-rumped Warbler.   A single bird, and on one day only.

Also the other day my better half and I saw a flock of 20 Cedar Waxwings.  Today during a lunch walk I saw the Cedar Waxwings, who, along with several American Robins, were busy eating berries.

Northern Shoveler

Eight Hooded Mergansers, fifteen or so Canada Geese, and numerous Mallards were also on the horseshoe pond by the Stone House.

For the first time in several weeks I spotted a Cooper’s Hawk:

I’ve been seeing American Kestrels west of Estes lately.  Here’s one above a prairie dog town:

Finally, here are a couple of shots of probably the last dragonflies in the area this year:

On an afternoon walk in the Bear Creek Greenbelt I spotted three adult Red-tailed Hawks in a single bare tree.  Two of them, on the left-hand side of the tree, were very vocal–they appeared to be screaming at each other.  The third, by itself on the right-hand side of the tree, was quiet.

After looking at the pictures, I saw that one of the two vocal ones was banded–the resident female.  I did not recognize the second vocal one or the third one, both of which have lighter eyes, indicating they may be younger adults.
