The 1st local TVs aloft were 9:09 AM EST. At 9:18 AM an immature CH flew
just over and past the watch and turned around to chase a Raven and dive on
another one perched on a pole, after which I watched it for 5 whole minutes
to see pictures a migrant while it kept flying higher and eventually flew
NW – not counted.
At 9:34 AM 2 Swainson's Hawk were seen first to the SE constantly flapping
with long and pointed wingtips flying SSW. At 9:48 AM I was binocular
scanning over Green Mountain when I saw 2 Prairie Falcon (brown-backed,
with dark coverts and axillaries through my 20-60x scope) flying south.

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
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk,
Swainson’s hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk.
Other raptors we see include Golden and Bald Eagles, Northern harrier,
Osprey, Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned
Hawks, American Kestrels, Merlin, and Turkey Vultures. Northern Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
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 14th,
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 small signs from
the southwest end of lot to the hawkwatch 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 top of the ridge, turn left,
head through the gate, and walk to the clearly-visible, flat area at the
crest of the ridge.  (Distance: 0.56 miles, Elevation gain: 259 feet)

[cobirds] Thursday, September 8th - Fort Collins Audubon Society hosts David Leatherman for “The Natural Highs of Lower Rist Canyon”

[Andrew Monson]

*Fort Collins Audubon* invites you to join a* virtual (and in-person watch 
party) program* featuring *David Leatherman*, retired Forest Entomologist, 
avid birder and photographer. David will be presenting* “T*he Natural Highs 
of Lower Rist Canyon*” *on *Thursday, September 8th, 2022; Announcements at 
7:00pm and Program at 7:20pm.*

*Virtual attendees: Enter the following link on your web browser at or 
before 7 p.m. and follow the instructions to join the meeting virtually: *
https://uso2web.zoom.us/j/83108184042  

*We will be enabling live closed-captioning for Zoom attendees to utilize 
as they wish.*

*In-person attendees: We will host a watch party at the Fort Collins Senior 
Center (1200 Raintree Dr). *

"The fancy word for it is an “ecotone”.  That is, the zone where two 
different habitat types meet.  Rist Canyon is one such place, a melding of 
prairie with mountains.  The wondrous math of it is 1 + 1 = 3: prairie and 
mountain species plus those of the foothills not typical of the other two. 
This presentation celebrates the rich diversity of one small piece of Lower 
Rist Canyon with emphasis on taxa characteristic of wildfire and bark 
beetle aftermaths.

David Leatherman is a retired Forest Entomologist, avid birder and 
photographer.

[cobirds] Black-throated Sparrow now in Gilpin

[David Suddjian]

We are viewing a juv Black-throated Sparrow at Central Coty Reservoir. Along 
the county road feeding near a green gate where the main inlet stream crosses.

Not on the eBird filter so maybe a county first?

[cobirds] Banding - Townsend's, Virginia's Warblers, CSR, El Paso Co, Tues.

[Steven Brown]

Hey COBirders,

Ok, so I admit I have no idea how migration works.  I’ve been reading 
Meredith’s posts from Barr Lake, and watching Birdcast maps and Dashboard to 
get an idea about when migrants might show up down here at Clear Spring Ranch.  
Birdcast shows HIGH numbers of birds passing over COS, but it looks like mostly 
at high elevation right before sunrise, and … I haven’t been getting more than 
a handful of migrants, especially warblers, with only a handful each day. Like 
Meredith, I’ve seen Wilson’s Warblers numbers replacing Yellow Warblers.  (I 
got my first Wilson’s Warbler the day after she did), but only 2-3 each day, 
not the 30’s and 40’s she is seeing.

Today looked like it would be the same - clear, warm, almost no breeze, and 
again, hardly any birds moving pre-dawn. 

It got better. 

There were small arriving waves of mixed species at dawn, and again about 9:00, 
but the biggest diversity arrived about 10:15, when usually everything is 
stopping because of the heat. Some birds were still finding the nets at 11:15, 
but by then it was 85o, and I closed down for the day.

Highlights banding today: 76 birds banded, now 950 for the month.

Wilson’s Warbler - 16 Mostly Hatch-year F, a few HYM, 2 ADM
Com Yellowthroat - 2, ADM, HYM
Yellow Warbler - 2, ADM, HYF
MacGillivray’s Warbler - 1 HYF
Virginia’s Warbler - 1  HYM
FOS Townsend’s Warbler - 1 HYF (chased into a net by a male Wilson’s!)
FOS Warbling Vireo (my latest first vireo by two weeks)
FOS Vesper Sparrow
Lark Sparrow - 1
Chipping Sparrow - 37 (450 for the season)
Brewer’s Sparrow - 2
Western Tanager - 1 HYF
Lazuli Bunting - 4, (now 120 for the season! Still mostly males)

Happy Migration, 
Steve Brown

[cobirds] New Yard Birds

[Kelly Ormesher]

Three weeks ago, my husband and I made the move from Colorado to Missouri. 
During the ten years we lived in Longmont, I had a life list of 91 birds 
for our home. I am missing my morning coffee on the back patio where we 
would listen and watch as birds visited our garden and made flyovers on 
their way to Union Reservoir and various ponds. Migration always brought 
some new visitors which were wonderful to experience.

Blue Jays, European Starlings, House Sparrows, and Eurasian-collared Doves 
are also regular visitors here. Red-bellied and Red-headed Woodpeckers have 
replaced visits from Downy Woodpeckers and Northern Flickers. Ruby-throated 
Hummingbirds and Northern Cardinals are abundant at my feeders. Sunrise and 
sunset flights by Chimney Swifts are a nice daily addition.

New migrants are arriving and I'm looking forward to exploring and 
branching out as we settle into our new home on Stockton Lake. Colorado 
calls to me and I know I will return a couple of times a year to visit and 
bird my favorite areas.

Cheers,
Kelly Ormesher
Greenfield, MO
