Re: [cobirds] Colorado Christmas Bird Counts Final Results (2023-2024)

[linda hodges]

Thank you for taking the time and energy to compile and share this with us,
Brandon. It's always interesting to see which species' numbers are
increasing and which are new to the count.

Did you happen to notice what species' numbers, if any, were down
significantly this year? Or missing altogether?

Again, your work is truly appreciated,
Linda

Observation start time: 09:00:00 
Observation end   time: 18:00:00 
Total observation time: 9 hours

Official Counter:Dustin Kohler

Observers:Archer Silverman, Janet Peters, Zach Hope

Visitors:
We had 85 visitors at the ridge today including an extreme runner who was
running close to 23 miles today, so she could practice for a 100 mile
run!!! We also had a guy who performed one of the best Bald Eagle
impressions I have ever heard visit the ridge.

Zach Hope, Archer Silverman, and Janet Peters joined me on the ridge today
helping me observe the native wildlife.


Weather:
Beautiful day up on the ridge, if not a little hot. Changing wind from SE
to NE, but all in all a good day.

Raptor Observations:
Migrants were seen in all directions around us. Our 2nd Cooper's hawk of
the year was seen over bare slope to the west.

We saw 2 local Bald Eagles, a local Golden Eagle, and a local Coopers Hawk.

Non-raptor Observations:
Possibly the same Woodhouse's Scrub-jay hanging out around the site along
with the Townsend's Solitare. Mountain Bluebirds are still on the move.

We saw some local Mule deer on both sides of Highway 70. 

Predictions:
Tomorrow looks to be a warm overcast day which is great for migration. The
wend shifts from a western wind to a favorable to migrants
south/southeastern wind. Join me tomorrow up on the ridge for a likely
amazing day.

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk

Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned

Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift,
American White Pelican, and Dusky Grouse. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by a Hawk
Counter and volunteers from 9:30 AM to 5:30 PM from March 1st to May 10th,
weather permitting.

Directions to site:
>From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow hawk watch signs
from the southwest end of the parking lot to the hawk watch site. The hike
starts heading east on an old two-track and quickly turns south onto a
trail on the west side of the ridge. When the trail nears the 

[cobirds] Colorado Christmas Bird Counts Final Results (2023-2024)

[Brandon]

Hi all,

Colorado had 51 official Christmas Bird Counts conducted this past winter
(December 14-January 5).  This year Colorado counts found 217 species on
count day, plus two during count week.  The total birds counted was way up
from last winter (763,932) compared to (669,780) in 2022-2023 (same number
of counts). Quite a few count reached the 100+ species number on count day:
Pueblo Reservoir (129), Penrose (118), Fort Collins (112), Colorado Springs
(111), John Martin Reservoir (108), Boulder (107), North JeffCo (102),
Denver (101), and Loveland (101). Another six counts made it to the 90-99
species range. Crook in north eastern Colorado, counted the most birds
(111,274), thanks to the large number of Snow Geese). There were a lot of
highlights, Colorado's first Christmas Bird Count record, of Pomarine
Jaeger at Pueblo Reservoir, also a first for count week for any Colorado
CBC, was a Laughing Gull there as well. A few other CBRC review species
were reported: Mexican Duck, Yellow-billed Loon, Pacific Wren, and Eastern
Towhee. A surprising seven species of shorebirds were found, Dunlin on two
counts and Long-billed Dowitchers on one count. Blue-winged Teal, Turkey
Vulture, Osprey, Franklin's Gull, Chipping Sparrow are all quite rare in
winter in Colorado. There's always some interesting water birds this year:
Trumpeter and Tundra Swans, plus feral Mute Swans, White-winged Scoters,
Black Scoter, Long-tailed Ducks, Red-throated Loon and Pacific Loons,
Red-necked Grebe, Short-billed, Glaucous and Great Black-backed Gulls. It
was nice that White-tailed Ptarmigan, Dusky and Sharp-tailed Grouse,
Gunnison Sage-Grouse and Greater Prairie-Chickens were all found on a
Christmas Bird Count in Colorado this past winter. Nine species of owls
were found. All three species of regular sapsuckers were found, six
Yellow-bellied, four Red-naped, and three Williamson's. The Phoebe show was
a bit crazy, 109 Say's Phoebes, six Black Phoebes, two Eastern Phoebes!
There were 21 Winter Wrens, one Carolina Wren, eight Hermit Thrush, one
Varied Thrush, six Gray Catbirds, one Brown Thrasher, one Sage Thrasher,
and four Northern Mockingbirds. Only Steamboat Springs found Bohemian
Waxwings (19), and only Fort Collins found a Common Redpoll on count day.
Chestnut-collared and Thick-billed Longspurs were found, neither are
regular in winter in Colorado, and two Snow Buntings as well. The warblers
were surprising, eight species were found. Black-and-white, Tennessee,
Orange-crowned, Black-throated Blue, two Pines, Yellow-throated, and a
count week Common Yellowthroat, along with 236 Yellow-rumped Warblers. A
few other sparrows of note: a Field, two Fox, 23 Harris's, 10
White-throated, Savannah on three counts, 24 Lincoln's, and 29 Swamp. Three
Pine Grosbeaks wandered to Weldona-Fort Morgan on the eastern plains. My
full summary has been sent to National Audubon and will be on their website
at some point.

Thanks to all the compilers, participants, and feeder watchers who have
helped with Colorado Christmas Bird Counts this past winter, and other past
winters.
