[Peter Burke]

COBirders,
A friend of mine posted this photo  of a female
Tufted Duck today so I thought I'd share it with the group. It's a bit of a
closeup, but interesting to look at...

Good birding,
Peter

[cobirds] Pacific Loon continues at Marston Reservoir

[Joe Roller]

I saw the previously reported Pacific and Common  Loons from a vantage
point
along Bow-Mar Drive, where one is allowed to pull completely off the
roadway onto the grass.
This is near the pin marker for the eBird hotspot named "Marston Reservoir
Complex--Marston Reservoir *East* End".

I looked due south and the loons were 2/3 of the way across the lake,
between a red and a yellow buoy. Seeking a
closer look, I drove to the cul de sac of West Layton Way, which can be
reached by going south on South Wadsworth St,
where the far west end of the water comes close to the chain link fence.
That way one avoids trespassing.

However from  that cul de sac, houses blocked views of the loon, and one is
prohibited from walking east into the nature
preserve.  So I tried from the far west end of the lake, thru the
chain link fence and although I could see the loons, but they were far off
and into the sun.

So IF you want to try for the loons, you might need to try all of those 3
vantage points or even Isthmus Park to get a decent view.

Hey, everybody. I enjoyed a pleasant ramble around Cottonwood Marsh &

*Virginia 
rail,* 1 *long-billed dowitcher,* 24 *Wilson snipes,* 1 *greater 
yellowlegs,* 1 *American bittern,* 1 *bald eagle,* 500+ westbound *American 
crows,* 1 *marsh wren, *1 *Lincoln sparrow,* and 20 westbound *great-tailed

[cobirds] Waxwings! In west Centennial, Arapahoe County

[Matt Rodgers]

I too spotted cedar waxwings this morning along the S Platte near the Audubon 
center as they were getting after the chokecherries and Russian olives along 
with the robins. Such a handsome bird!!

All the best, Matt Rodgers

[cobirds] Calmer times in Boulder/Larimer

[William H Kaempfer]

John Vanderpoel and I headed out late this morning to visit some northern 
Boulder and southern Larimer reservoirs.  As opposed to the goings on of the 
previous seven days, not too much excitement this time around.  The east side 
of Terry Reservoir off US 287 in Boulder County north of Longmont had a at 
least 10 Bonaparte's Gulls, and Dry Creek Reservoir SE of Carter Lake had a 
Surf Scoter and a lingering Say's Flycatcher.  Some interesting paradoxes out 
there, though.  Newell Lake just east of Berthoud had 635 Ring-billed Gulls in 
a single species (as far as we could tell) flock.  Hummel Reservoir, about 0.5 
miles away across fallow fields, and roughly the same size, had none.   Our 
only Canvasbacks, 68 of them, were also all together in the not very large Twin 
Mounds Reservoir east of Campion.

[cobirds] Around West Arapahoe

[Jared Del Rosso]

I spent the morning and early afternoon around west Arapahoe. Highlights 
today (10/28) include: 

   - at Blackmer Lake: a rather later Western Tanager. Swamp Sparrow. At 
   least one, possibly two, striking, very dark Red-tails. 
   - in Littleton, a flock of 45 or so Sandhill Cranes, catching a thermal 
   around Broadway & Littleton Blvd. 
   - my first Merlin of the year, at the Rollin D. Barnard Equestrian Park 
   in Greenwood Village. As the local raptors typically do, the Merlin was 
   perched along the enormous transmission towers. I got to see it 
   (apparently) flush north when a Red-tailed Hawk came through, then u-turn 
   and head south to pursue a flock of waxwings already in flight.

[cobirds] N. Shrikes and Sandhills east of Longmont last week

[Kat Bradley-Bennett]

Jamie Simo and I did our monthly survey of the Peschel open space east of 
Longmont and we had two firsts: 2 Northern Shrikes and 3 Sandhill Cranes! 
The Sandhills weren't in the open space per se, but in the cornfield just 
south of it. 9 tom turkeys, too!

[cobirds] Waxwings! In west Centennial, Arapahoe County

[kevygudguy via Colorado Birds]

Hello Fellow Birders,
   A small flock of Cedar Waxwings just invaded my little townhouse yard in 
west Centennial, near Holly & Arapahoe.  Gobbling down the little fruits on the 
"crabapple" tree (I have no idea what kind of tree it really is, something the 
builder planted when these places were built in the early 80's).
   We've also been inundated by robins the past few days.

I saw your revised checklist.
Would help me learn the structural points, etc if you re-attached the
close photos you took of the RN Duck, as were on your earlier list.
Thanks, Joe
