[cobirds] late post, Sage Thrashers feed juv, White ROS, Jeffco

2011-09-10 Thread Kayleen A Niyo
Sorry for the late post due to company, etc.  We saw 3 Sage Thrashers in
upper White Ranch Open Space on Mon, Sep 5.  One of the three was a juv and
one of the others was feeding it.  I have seen and photographed them there
on 18 Aug 2009.  Few other spp of note in lower Wht Ranch OS or Golden Gate
Canyon SP that day.

 

Amazingly, we were the only visitors to Rocky Mt Arsenal NWR on Tues, the
6th, in cloudy weather.  Lots of Swainson's Hawks including an adult and juv
together on adjoining poles.  Flocks of Lark Sparrows, Chipping Sparrows, W
Kingbirds, Am Kestrel eating prey, and young Monarch caterpillars feeding on
Asclepias (they better hurry!).  The fall native grasses and forbs are
gorgeous!

[cobirds] Blackpoll Warbler -- Pueblo County 9/10

2011-09-10 Thread Brandon K. Percival
This morning around 730am or so, I saw a Blackpoll Warbler near the Arkansas 
River, in the eastern part of the Osprey Picnic Area in the Rock Canyon Picnic 
Area, below Pueblo Reservoir dam.  I never saw the bird again.  I've been 
seeing Eastern Phoebes regularly at this spot, and today there were at least 
three of them.  At least three Townsend's Warblers were around this morning as 
well.  Also, a Hammond's Flycatcher and a Plumbeous Vireo.  This area in Rock 
Canyon has been quite birdy most days recently, with several eastern surprises 
appearing here.  Hopefully there will be more coming!

Glenn Walbek saw the adult Long-tailed Jaeger flying around Cherry Creek 
Reservoir this afternoon.  I think it was found by someone else earlier.  
Hopefully the people who have seen the bird, will give more information.

[cobirds] RMBO banding at CBR Saturday

2011-09-10 Thread Steven Brown
Hi COBirders,

Almost no birds around at sunrise, only a handful banded by 9am, a bunch of 
Chipping Sparrows about 11am, then all of a sudden we had 42 banded birds by 
closing.  Since when do birds get active only after it gets hot?

No banding tomorrow, we'll resume Monday 9/12.

Banded today

OVENBIRD recaptured from yesterday

W Wood Pewee - 3
Dusky Flycatcher - 2
Cordilleran Flycatcher - 1
House Wren - 1
Am Robin - 3
Gray Catbird - 2
Brown Thrasher - 2
Wilson's Warbler - 12
Chipping Sparrow - 12
Lazuli Bunting - 4 all young birds

Notes : lots of WIWA's yesterday - fewer today. Few flycatchers yesterday, more 
today, and lots of pewees.   Large flocks of Chipping Sparrows moving around 
the grove late in the morning every day this week.  We're hoping for a weather 
change that brings in more diversity - it has been calm all week (at CBR?)
Have a birdy weekend,

Steve Brown
Colorado Springs

above) and they were better than by $500 binos!  :-)

[cobirds] Long-tailed Jaeger, Cherry Creek SP

2011-09-10 Thread Glenn Walbek
The adult Long-tailed Jaeger, found earlier today by Cheryl Teuton was still at 
Cherry Creek Reservoir as of 5:30 pm.  This lovely bird is all over the lake 
but probably best found from the Lake Loop.  It chases gulls, loafs on the 
water and is in turn, harassed by gulls.  Thanks to Cheryl for finding this 
beauty!

[cobirds] RMBO Barr Banding Station Update, 9/10/11

2011-09-10 Thread Meredith
We got our wish for more birds for Barr's Annual Fall Bird Fest.  At least
150 people visited our station today, and we had 50 birds to show them - 34
banded today, 1 banded in 2010, and 15 banded previously this season.

 

Spent some time with Sibley's being sure we had a correct ID on a rare bird
- an immature MAGNOLIA WARBLER.

 

In my head I've been comparing this year with last, which I viewed as a
fairly typical Barr season in terms of numbers and species.  I have been
thinking that Yellows are high and Wilson's low.  Decided to compare our 4
dominant species this year to last, to date, and it is pretty interesting:

 

Chipping Sparrow80 (2011), 24 (2010)

House Wren 49 (2011), 82 (2010)

Wilson's Warbler 116 (2011), 310 (2010)

Yellow Warbler183 (2011), 49 (2010)

Total, 4 species  428 (2011), 465 (2010)

 

Someday I'll go back and see if any time in recent history we've caught 183
Yellows.  (Our total last year was 51.)  And, where are the Wilson's??

 

Okay, back to today...Here's the rundown on the new birds caught (total 35):

 

Western Wood-pewee 1

Cassin's Vireo  1

Black-capped Chickadee 1

Rock Wren  1 (FOS)

House Wren 5 new, 1 return from 2010

Orange-crowned Warbler 1

Yellow Warbler4

Magnolia Warbler 1

Wilson's Warbler 3

Chipping Sparrow16

 

Day off next week is Tues (9/13).  Otherwise open every day through next
weekend.

[cobirds] Weld: Sprague's Pipit, Boulder: Green Heron

2011-09-10 Thread Steven Mlodinow
Greetings All,


First, the positive data

There was a Sprague's Pipit that flushed up calling from a field along the n 
(towards ne) side of Union Reservoir. There is field of clover on the north 
side, and both grassy and relatively tallish grass fields nearby.



At Cottonwood Marsh, there was a Green Heron.


The negative data:
We could find not a single migrant passerine. Beyond C Yellowthroat, our only 
warblers were a Wilson's and an Orange-crowned at Glenmere Park in Greeley. We 
had NO warblers, vireos, or flycatchers at Walden (not even a kingbird). Ish 
Reservoir, like many places, had great shorebird habitat without shorebirds 
(except Killdeer). Weld CR 59 pond is too flooded for shorebirds, and though 
some habitat remains in the watery Lower Latham ponds, no shorebirds (except 2 
Killdeer) were present.


Good Birding

[cobirds] Long-tailed jaeger continues

2011-09-10 Thread Cole Wild
Katrina Stowasser and I refound the Cherry Creek (Araphoe County) Long-tailed 
Jaeger at about 7 o'clock this evening (9/10). It was sitting in the Marina 
cove fairly close to the spit from the Lake Loop. Poor digiscoped photo were 
obtained.
