[cobirds] Chico Basin Ranch birding on May 14th

[Brandon]

After being out of the state for a week, I got back to birding in Colorado
a bit today.

The Pueblo County side of Chico Basin Ranch (Headquarters and Rose Pond),
male Black-throated Blue Warbler, Nashville Warbler, four Northern
Waterthrush, American Redstart, Cassin's Vireo, singing Least Flycatchers.

On the El Paso County side of ranch (banding station), singing male Hooded
Warbler, male Magnolia Warbler, male Black-throated Gray Warbler, Northern
Waterthrush.

I ended with 13 species of warblers there today.

Just a reminder, any birders going to Chico Basin Ranch are required to pay
$15 per person to visit the ranch each day they go there.  Most of us local
birders have paid the annual fee of $125.  I am not sure if everyone who
was out there today from out of town, signed in and paid.  If you aren't
planning to pay, then please don't go there.  The people not paying, may
ruin the birding for us local birders who go there often.

Total observation time: 4.5 hours

Official Counter:Emma Riley

Observers:Aarohi Barman

Visitors:
We saw 4 visitors at the ridge today including a Jefferson County ranger
coming to collect supplies, making the end of the season really sink in. 

I have been saying this all season but it needs to be said again- thank you
to everyone who has made this season run efficiently and brought skill,
passion, and great company to the count. We could not do it without the
help of our DFO volunteers. We will see you next spring, and happy birding
in the meantime! 


Weather:
Light rain and low clouds came and went at the ridge for most of the
morning until settling in in the early afternoon. Winds were from the NE
and never got too strong. 

Raptor Observations:
All four of our migrants today came through the clouds or below eye level,
but the low visibility made a confident identification challenging on two
of those birds. Our final migrant of the season was an immature RT. One
local TV was seen today and the local RT weren't seen until we were hiking
out.  

As it is the last day of the season it is time to take a look at our final
numbers!

Total migrants counted this spring: 2259. Lower than last years count
(predominantly due to lower RT numbers this year), but still the second
highest season count since 2005. 

OS season count is equal to the highest count on record from 2002. 

Highest CH count since 2005. 

Highest SW count on record, 18 birds higher than last years record breaking
season. 

Highest FH count on record (since 1997- 90s data still being entered) by 1
bird. It is worth noting the odd push of FH at the end of our season this
year. 

Highest AK count since 2005. 

Highest ML count on record. 

And the star species of the season- the BW! Our season count was almost 3x
last years count, and 1.6x more birds than our highest season on record.
These birds showed out this year and we are really looking forward to see
what the coming years bring for this species. 

Non-raptor Observations:
Passerines seemed to have settled into the ridge overnight following a
whole bunch of moths! YRWA, CHSP, BHGB, GTTO, SPTO, BRSP, VESP, DEJU, BTHU,
ROWR, AMRO, SCJA, BBMA, ROPI, and CORA were all highly active today giving
us great looks at many of these birds.

[cobirds] Sabine's Gull, El Paso County

[David Tønnessen]

Birders,

Excuse the late post as I had to get home and make some mother's day
breakfast, but in the hour I had outside this morning I enjoyed a gorgeous
breeding plumaged adult Sabine's Gull foraging near the parking lots at Big
Johnson Reservoir in El Paso County. There are only a handful (4?) of other
records for this species in Colorado in May, per eBird. Also present were
Franklin's Gulls, Forester's Terns, a good number of Black Terns, and crazy
numbers of swallows put down by the low stormy clouds.



Happy Mother's Day and Happy May Birding!

[cobirds] Migrants, El Paso County, 5/14

[Chris Selvig]

My neighborhood, Shooks Run in downtown Colorado Springs, is awash in migrants 
today.  Of note:

Western Tanager - 10 sighted in about 30 minutes
Bullock’s Oriole - 5
Warbling Vireo - 2, and a new yard bird for me.
Swainson’s Thrush (following on a Hermit Thrush that hung around for much of 
the day yesterday.)
FOS Yellow-rumped and Yellow Warblers.
Large flocks of Chipping Sparrows

On the opposite side of the migration spectrum, a straggling flock of Cedar 
Waxwings is still around.

[cobirds] Bird Conservancy of the Rockies, Chatfield Banding Station - May 13, 2023

[Meredith McBurney]

After two days of rain, we anticipated a busy morning yesterday, if not 
with migrants passing through then our summer residents out feeding.  But 
it was pretty quiet, with just 24 new birds caught.  There was a nice 
variety, so it was a good learning experience for our visitors from Denver 
Audubon's Beginning Birder class.

Lots of water in some areas of the station; several of the river nets could 
not be opened because the water was so high.  And special thanks to the 
volunteers who added a day to help convince the bobcat to go elsewhere!  
(We did not see him/her.)

Here's the breakdown:

Least Flycatcher 2
Hammond's Flycatcher 2
Dusky Flycatcher 1 (FOS)
House Wren 2
Gray Catbird 1 new, 1 banded 2021, recaught 2022
Orange-crowned Warbler 1
Yellow Warbler 2 banded 2022, 1 banded 2021 (of the 22 YEWAs caught to 
date, 12 were already banded.  All but 1 of the 22 were adults.)
Yellow-rumped Warbler, Audubon's 2
Common Yellowthroat 1
Yellow-breasted Chat 2
Green-tailed Towhee 3
Lincoln's Sparrow 2
Red-winged Blackbird 1

We are rained out today, closed on Monday.  Hope to be back out on 
Tuesday!  Denver Audubon has scheduled one-hour time slots at 7:30, 8:30 
and 9:30 for visitors on weekends; visit here 
 to register.  (I believe many time 
slots are already sold out, so register soon if you would like to visit.)
