to boot.

[cobirds] Bohemian Waxwings, Hoosier Pass

[Alan Versaw]

Saw roughly 25 (give or take 5) Bohemian Waxwings late Sunday afternoon, 
3/25, driving south toward the summit of Hoosier Pass. Perching at tops of 
trees--not terribly close since the trees were very high. I believe there 
are three major hairpins on Colorado 9 above where I saw the birds. Point 
was plotted accurately on eBird.

Observation start time: 08:00:00 
Observation end   time: 14:00:00 
Total observation time: 6 hours

Official Counter:Joyce Commercon

Observers:Jane Haddock

Visitors:
David, a volunteer at Barr Lake State Park, dropped by for a brief visit
early in the morning and was present when one of the early American Kestrel
migrants whipped past the platform. Jane Haddock spent several hours
helping to spot and follow many of today's raptors; she was incredibly
helpful on this busy day! Of the hikers and bikers on the trail, only a few
came up and then only for the view.   A quiet and orderly group of kids,
likely with attending adults, also apparently filed up onto the platform
for the view, but several possible migrating raptors had our attention at
that moment so that could have been a hallucination...


Weather:
The cool, mostly-cloudy day opened with thin fog in the valleys and a
lowered cloud-ceiling which shrouded the top of the western ridges.
Ninety-five-percent cloud-coverage (at the start of the watch) decreased to
40-percent by the 10:00am MST but gradually moved back to near-total
coverage by the end of the watch.  Visibility was poor in the morning, but
became reasonably better by mid-morning as the fog thinned to a light haze
and the clouds lifted above the western ridges. Winds, predominately from
the northeast and east, increased from bft 2 to bft 4, and seemed to become
colder. Temperatures increased from 5 C to 10 C , but then dropped back
down to 9 C in the last hour.

Raptor Observations:
Most of today's migrants passed relatively close to the Ridge, either right
along it or just to the east over Rooney Valley. Height-of-flight seemed to
be, on average, just a bit higher during the 10:00-11:00am MST hours when
it was the most sunny (cloud-cover was at its lowest), but all migrants all
day were at heights-of-flight visible to the unaided eye. 
The first highlight of the day was a classic, adult, female-type
Rough-legged Hawk that powered its way north in the morning, low, in the
western valley, pausing only to circle up briefly near I-70. The second
highlight was a dark-morph Ferruginous Hawk adult that passed northeast
over the Ridge close to the platform.  Delightfully, many of the American
Kestrel migrants passed very close to the Ridge, either directly over it or
just to the east. 
A local pair of Peregrine Falcons soared amiably just south of the
platform before noon. Late in the watch, a local adult Golden Eagle came
north along the Ridge only to be attacked repeatedly and persistently by a
local Red-tailed Hawk near I-70 until it left the area to go west toward
Cabrini Shrine. The local Red-tailed Hawk pair made a couple of appearances
in Rooney Valley, dropping legs and doing roller-coaster movements. The
female Red-tail of the pair (that has the whitish patch on the front of her
head) perched on a Rooney Valley phone pole occasionally and also
kite-hunted a few times.

Non-raptor Observations:
At least 85 American Robins were seen moving in 3 

[cobirds] Prairie Birds, SE El Paso Co, Monday

[Steven Brown]

Hey again, COBirders,

After the fog lifted this morning I ventured out to SE El Paso County on 
Hanover Road - mostly to look for Roadrunners, Burrowing Owls, and Mountain 
Plovers, all of which remain unseen by me.  I did a loop of Hanover Road, 
Milne, Squirrel Creek to the end, Myers and back on Hanover. I only could find 
one active prairie dog town, at Squirrel Creek and Peyton Hwy.

It is VERY dry out there, but I did see some typical birds, and a few new 
arrivals. Seen today:

Curve-billed Thrashers - 3 pair. First pair S of Hanover Rd on Meridian, Second 
on Milne Rd N of Hanover Rd, and Third, right next to the fire house in Hanover.
2 Mountain Bluebirds, Says Phoebe, Great Horned Owl - at the far end of 
Squirrel Creek Rd. 
Ferruginous Hawk
Swainson’s Hawk
2 Scaled Quail
ONE Loggerhead Shrike on Hanover Rd (we usually see dozens and band many!)
Lotsa Red-tails, kestrels, ravens, Horned Larks, and W Meadowlarks. Couldn’t 
spot any sparrows.

And for those keeping track - I spotted two White-throated Swifts at Garden of 
the God Park this afternoon - my first time this year, But be warned - the 
human traffic, full parking lots, and stop-and-go cars this week have made it 
tough to find a spot for viewing.  Maybe the crowds will dissipate after spring 
break!

Happy Spring,
Steve Brown

[cobirds] Vermilion Flycatcher

[Karen Drozda]

After a thorough search of the area east of Carolyn Armstrong Fishing 
Access, the Vermilion Flycatcher was not spotted..so far today. I covered 
the hillside to the east all the way to Smoky Hill Parking lot.
I searched from about 1030 to 1230. There was a breeze from the north and 
it was 50 degrees. It was fairly "buggy", but no flycatcher in sight. I 
did, however, come upon a lone Sage Thrasher.

[cobirds] My Yard: Spring Arrivals Common Grackle and House Wren

[Ben S]

Hi all - 
Saturday, the 24th, I went into my front yard to hear a Common Grackle 
calling perched in my acacia tree. In May, we will be tired of them, but 
for now, they are exciting. This morning, I heard a House Wren singing and 
breifly saw it in my lilac bushes.

[cobirds] Carolina Wren in Lafayette, Boulder County

[Lindsey Wohlman]

Apologies if this is a duplicate post, my original looks to have incurred 
an error)

3/24 around 2PM I made a video recording of an unusual call. Discussion and 
general consensus on CFO FB page is that it is a Carolina Wren. Vid does 
not have visual confirmation. Location - Coal Creek Trail just east of the 
Avalon Trailhead in Lafayette, CO

Recording can be found 
here. 
https://www.facebook.com/groups/CFObirds/permalink/10155131942552038/?comment_id=10155133110297038_comment_id=10155133451687038_id=1522029560928582_t=group_comment=notif

Here's a map detailing where the video was shot and the general area of 
bird location.
