[cobirds] Migration Galore -- NE Colorado

[Chris Rurik]

Hey Cobirders --

David Dowell and I looped through Washington, Logan, Phillips and Sedgwick 
counties today. Migrants were in many places and I saw so many lifers (12) 
it's almost embarrassing, considering I've been living in CO a year now.

We started off the morning with those notorious long-distance migrants, 
GREATER PRAIRIE CHICKENS, at the previously reported location (Logan CR 93 
between CR 44 and CR 46). Also present were clay-colored sparrows and brown 
thrashers.

Haxtun had a few common residents and migrants, nothing special.

Holyoke City Park was quite an experience, feeling like a mini fallout. Two 
BLACK-AND-WHITE WARBLERS, a NASHVILLE WARBLER, a TENNESSEE WARBLER, six 
redstarts, warbling and red-eyed vireos, yellow and Wilson's warblers, 
pewees, an empid, etc. all very active.

The Holyoke cemetery was okay, with olive-sided flycatcher and orioles.

Our takeaway from Julesberg: skip the town and the cemetery, bird the rest 
area. The rest area (right on I-76) had a PLUMBEOUS VIREO and yellow, 
Wilson's and redstart warblers.

Ovid Woods was pretty quiet in the heat of the afternoon, but we saw a 
DUSKY FLYCATCHER, two RED-BREASTED NUTHATCHES (early for the plains), and 
some surprising wild turkeys, among others.

Tamarack was hot and dry.

We ended the day at Prewitt, planning to bird the inlet canal, but every 
dirt pulloff had an encampment and every field had at least a couple of 
hunters. Maybe there is a special Labor Day hunt going on. Not sure what 
the story is or if the hunters will be there tomorrow. So we went to Plan 
B, land-birding the west side of the reservoir, then walking out onto the 
half-empty lakebed to view thousands of shorebirds.

At Prewitt, we saw Townsend's warblers, blue-gray gnatcatchers, a single 
CASPIAN TERN, marbled godwit, long-billed curlew, solitary sandpipers, 
hundreds of Wilson's phalaropes and a handful of red-necked phalaropes, 
avocets, stilt, stilt sandpipers, a bald eagle, many ducks and pelicans, 
etc. etc.

It looks like they are draining Prewitt very fast, so the shorebird habitat 
may not last much longer. Again, not sure what the story is. Sunset sure 
was beautiful though.

Happy fall and good birding to all,

[cobirds] Larimer County hawks and other birds

[Libby Edwards]

Getting out of the heat this past week, I have spent a delightful time
above treeline.  Two days ago on the way to Mount Ida from Poudre Pass, I
saw 2 roughed-legged hawks hovering and then diving into the krumholtz.
 They did this several times.  On this same trip, I watched a prairie
falcon buzz a few marmots who were calling in alarm.  Along the way there
was a female ptarmigan with 2 pretty small chicks among the rocks in the
tundra.  I hope they grow fast before the cold sets in.

Today on the way to Montgomery Pass near Cameron Pass, there was a large
flock of mixed warblers moving upslope in the morning in an open meadow
surrounded by dead and live spruce and fir.  I was able to ID male and
female Wilson's warblers and male and female Townsend's warblers flitting
around with lots of juncos and chickadees.  I watched parent chickadees
feed their fledgling young.  Then on top of the pass, 2 rough-legged hawks
were soaring up and down the ridges, over our heads.

In the yard yesterday in our big honey locust there was a yellow warbler, a
red-eyed vireo, and a western tanager.  Migration is on.

[cobirds] MacGillivray's Warbler and other yard birds / Denver

[Dave Cameron]

Our second-ever MacGillivray's in the backyard was present yesterday 
afternoon and this morning, during a very busy afternoon back there.  
 
Also of note was what will be a new yard bird if it'll ever sit still long 
enough for positive ID, but a very probable Wilson's Warbler.
 
Other regulars, many with fresh youngsters along, include:
 
BC Chickadees (including one with a black eyeline, but otherwise mostly 
white head)
1 Mtn Chickadee
1 Blue Jay
Red-breasted Nuthatches
Mourning Doves
1 Chipping Sparrow
EC Doves
1 Empidonax Flycatcher
2 already-winter plumaged Am. Goldfinches
House Finches/ House Sparrows
Barn Swallows
 
A surprising lack of raptor activity.  I typically get a Cooper's or 
Sharpie drive-by with this much feeder activity.  Though one suddenly quiet 
half-hour this morning may suggest that there was one in the neighborhood.
