After commitments in Denver this afternoon, I stopped by City Park for a
while. Among the many Yellow-rumps I found a Northern Parula just northwest
of the gazebo at the west end of Ferril Lake. Other storm-blown birds in
the park included Mountain Bluebirds, a Vesper Sparrow, and hundreds of
The issue of swallow ID has been understated for decades as far as books
and articles go. Sure, gulls, shorebirds, seabirds are traditionally among
the tougher families for US birders. Well Empids, sparrows, fall warblers,
etc etc as well.
USA swallows are highly mobile and visible species,
Hi all,
Today I was up in Summit County and was able to do some birding. At Bills
Ranch Lake there were many *Cassin's Finch, Red Crossbill, Pine *and*
Evening Grosbeaks, *as well as a *Fox Sparrow* in a clump of willows
nearby. There was an *American Kestrel *and *Northern Goshawk *on the
Hi COBirders,
I decided to take a chance on the cold, snow, ice, and mud this morning and try
some banding at CSR. Things were definitely moving!
I banded an Audubon's Warbler (SY Male), and 3 Orange-crowned Warblers, saw
several more, and several "bounce-offs" by Myrtle Yellow-rumped
This morning I had a Sanderling at Mack Mesa Reservoir feeding along the
shoreline with 13 American Avocets and 2 Willet's. There was also a flock
of 20 Eared Grebes in the middle of Mack Mesa Reservoir, which is located
in Highline Lake SP.

Park, on my morning walk today in the snow I found a first-of-year
Orange-crowned Warbler on the west end of Estes Park. No other eBird reports
yet for this year up here. I also encountered a large flock of

Speaking of swallows, there were several hundred swallows of all 5 expected
species as per Joe Rollers last post this morning on Sloan's Lake in Denver
Birds are best viewed from the bridge along Sheridan Blvd on the W. side of

Yesterday, Nick Moore and I birded Weld County, starting at Crow Valley and
finishing at Union Reservoir.
The fallout was impressive, if not more for bird numbers than rarity.
We had 125 species in all.
The rarest birds were a Western Palm Warbler at the Eaton Cemetery and a

There is often great info on CObirds about sorting out rare and tough,
look-alike bird species.
But for many less-experienced members of our field class fraternity and the
scope sorority,

Hi all,
I found a Worm-eating Warbler this morning along Boulder Creek below the CU
Rec Center. It was near the west end, south of the creek, just east of the
pump station (there is no longer a footbridge across the creek at the pump
station, so you'll have to cross the creek closer to Folsom
FYI - The Chatfield Banding Station will not be open tomorrow because of
the wet and cold and likely precipitation. Hoping for better weather soon.
