Hello All,
On May 29 and 30, Chuck Aid, Audrey Boag, Michael Kiessig, Rob Raker
and myself did the annual Ovenbird Count in Willow Springs Open Space
(WSOS). Willow Springs Open Space is private open space and this is
the 5th year for my survey. Each of the annual surveys have been
Hello,
I initially reported the breeding pair of Mississippi Kites last year
near Watson Jr. High in Security. They had two young.
They returned this year on May 6th and while she isn't on it all the
time, the same nest seems to be in play.
I am now wondering if there may be a colony of
A Yellow-throated Vireo is at Chatfield SP nesting with a Plumbeous
Vireo. It was found by a Wild Birds Unlimited/RMBO field trip. Go
south from Kingfisher Bridge on the west side of the Plattte River for
5 minutes until you come to a scraped-off bare area on the right.
Continue for 50 yards where

Here are some details.

Hi All,
We made a quick stop at Lagerman Res this morning. Nothing extraordinary,
but a Turkey Vulture and Black-billed Magpie feasting on a roadkill
Black-tailed Prairie Dog, a pair of Clark's Grebes, and a flyover
Great-tailed Grackle were nice. The Ospreys were on their nesting platform

I first heard (peee-a-weee) and eventually saw an Eastern Wood-Pewee in a
small cottonwood grove inside the fenced alfalfa field on the Chico Basin
Ranch (fee area). This area is at the very south end of the alfalfa field
(recently cut) and about ½ mile south of Rose Pond. The
Hi COBirders,
Nick Komar found a Yellow-throated Vireo mated with a Plumbeous Vireo in

You
Cobirders,
Thanks to Wild Birds Unlimited and Rocky Mountain Bird Observatory for hosting
this hike. Thanks to Joe for posting the info, to Becky Campbell for seeing the
yellow-throated first and Nathan McAdams for then re-spotting it. We were
alerted to the birds by the singing of the
Folks,
Loch and I went to look for the Yellow-throated Vireo at Chatfield (following
an interesting morning at CVCG) and found her within seconds of arriving at the
spot described by Joe Roller. The Plumbeous Vireo was singing and the Yellow
Throated Vireo was never far from the Plumbeous.
While it took some patience both vireos were seen from the paved path at about
3:30.
After the scraped off area it's about 85-100 yards to a fallen log on the
right that Joe Roller has placed three sticks across.
This is the point from which I saw both birds on either side but close to the
The cemetery was beautiful and full of interesting things today:
Confirmed the very recent hatch of two young in the tripledecker Broad-tailed
Hummingbird nest
Watched a different female hummer near her first-time nest flycatching for
mosquitoes
FOY fledged American Robin and Chipping Sparrow
Interesting to note the differences from day to day - yesterday the majority
of our birds were previously-caught-this-season breeding Yellow Warblers;
today we had more species and no clearly breeding Yellows. Here's the
breakdown:
Downy Woodpecker 1 banded earlier this season; male with

This evening I had 9 Bushtits circumnavigate my yard moving from spruce to
ponderosa to locust to aspen before heading across the street.
Also, on Sunday, 5/27, I had a White-throated Swift flying around my
neighborhood.

This afternoon, I was able to watch the Yellow-throated and Plumbeous Vireos.
Most the time they would forage high in the cottonwoods before announcing their
presents near the nest. Every once in a while they would forage low and
collect nesting material. I only witnessed the Yellow-throated
Greetings All,
Glenn Walbek, Loch Kilpatrick and I headed out to Crow Valley this morning.
Migrants were few, but we did find a female BLACK-THROATED BLUE WARBLER, an
AMERICAN REDSTART, 2 RED-EYED VIREOS, and a PLUMBEOUS VIREO. Also of note was a
late migrant White-crowned Sparrow (Gambel's)
Yesterday I saw my first of the season Blue Grosbeak, actually one male in
each of two locations in the Canon City area. This evening I heard my
first of the season Common Nighthawk call. That is late for both of these
species. I have not seen an empid one though I may have a heard one call
