[cobirds] Patch birds - Douglas

After walking the conifer patch, while Urling talked to the mail delivery woman, I briefly saw in immature Red-headed Woodpecker. It perched in a dead cottonwood for 10 seconds, then flew off, and we couldn't find it again.

We also recorded our first Pink-sided Juncos today, along with most of the usual species. A lot of corvids (Steller's, Blue, Scrub, magpie, crow & raven.

Observers:	Liza Antony

Visitors:
A couple walking up the trail remarked about the "heavy camera" equipment I was carrying. I explained that it was a 'scope and told them of and showed them the hawk watch location. A mountain biker (presumably riding north on the Hogback Trail) confused as to where the trail had "disappeared" â€" I showed him where it had turned off downhill.

Weather:
The predicted forecast today on weather.gov was for light winds from the W>SW>SE with strong NW winds after 3 PM, while earth.nullschool.net expected light winds from the West. At the watch there were Level 3 winds from the WSW which dropped to Level 2 in the next hour followed by East winds at the same (lack of) intensity. There was excellent cloud cover 60-70% with reasonably good clear visibility to 16 km.

Raptor Observations:
We ended the month (paraphrasing and with apologies to T.S. Eliot https://tinyurl.com/mt7zj8r7) not with a bang, and not even a whimper. When we got to the watch there was an adult Eastern RT perched on 1 of the 3 poles north of the watch. Another non-migrant RT as well as a Western adult RT (with darker underwings and a dark throat) were the only raptors of any kind seen today. No migrants at all. Kerrie Lagon a hawk enthusiast had emailed me yesterday morning at 10:24 AM MDT "I just want to let you know that Iâ€™m driving down University at the corner of University and Orchard there was a kettle of turkey vultures 60 circling in the thermals along with one Swainson's and one hawk that was dark morph with white on the tip of his wings and they were circling and circling and then they took the thermals and headed southeast towards the corner of Holly and Arapaho Open space which is where they usually kettle up. I wanted to let you know and that this is a phenomenal I see every year around my house." I scanned with binoculars and my scope in that direction and did not see any hawks there, though it's difficult finding any hawks against the background of trees and houses, none were seen just above the horizon either in the direction (which would be just north of Marston Reservoir). This together with the COBirds post by Doug Ward 2 days ago https://tinyurl.com/4k7bn36p suggests that there is a migratory raptor movement but away from Dinosaur Ridge. On a recent bird walk with Joey Kellner and discussing the dearth of SH at the watch (compared to Manzano Mountains HawkWatch NM where they've had 1644 SH this month including a day with 497, and the Commissary Ridge HawkWatch WY which has had 393 SH including a day with 166; and these hawk watches are South and North respectively, and quite a ways west of Dinosaur Ridge) he told me that SH form staging groups of 75-100 on the eastern plains of Colorado c. 90 miles east of Denver.

Non-raptor Observations:
Mountain Chickadee 1, Townsend Solitaire 3, Blue Jay 2, Barn Swallow 1, House Finch 6, Black-billed Magpie 1, American Robin 38 flying south, Black-capped Chickadee 1, Woodhouse's Scrub-Jay 6....These were some consolation to the lack of migrant hawks for us who have recently moved here from New York State. 2 hot air balloons to the NE, where there was some smog visible along the horizon.

Report submitted by DAVID HILL ()
Dinosaur Ridge - Denver Field Ornithologists information may be found at: http://www.dfobirds.org
More information at hawkcount.org: [Site Profile] [Day Summary] [Month Summary]

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, Swainsonâ€™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] Eastern Blue Jay, Golden Gate Canyon State Park, Jefferson County

At the top of Mountain Base Road, I heard an eastern Blue Jay calling from an aspen grove! I've never heard one before in Golden Gate Canyon SP, and I lived just north of it for 25 years and have birded there often since moving to Louisville. The two Steller's Jays that I saw were quiet.

On October 9 DFO is hosting Nature's Educators in person with eight live raptors at the Denver Audubon Center near Chatfield State Park from 1-3 PM. Get the details and sign up here if you are a member of DFO. If you are not a member, sign up here. There is a modest cost to attend.

The following programs are free and offered via Zoom. Members and non-members alike can sign up here.

On October 12, David Hill will present his hawk ID program at 7 PM.

On November 17, David Suddjian will drop a Bird Bomb program on Forest Hawks at 7 PM.

On November 28 at 7 PM, Emma Riley, the hawk watch counter at DFO's spring count at Dinosaur Ridge will present Hawk Watch 2022: Looking Back and Looking Forward.

Finally, on October 15, participants in either the October 9 or the October 12 program will be invited to a field trip to Dinosaur Ridge to put their skills to the test.

This is a great season to learn about hawks that migrate through the Denver area and consider volunteering for Hawk Watch at Dinosaur Ridge this spring. We hope to see you there!

[cobirds] Bird Conservancy of the Rockies Chico Basin Ranch 9/29/22

With not having much experience with bird migration in the West, I thought there might be a bit of migration overnight with the light NNW wind. It appears that a few birds dropped in this morning. Twenty-three bird species were captured at the station including a special highlight of a Yellow-bellied Flycatcher. Which I was told it is the second one banded here at Chico Basin. The White-crowned Sparrows and Wilson's Warblers were the dominating species.

Here is the Catch of the Day:

72 New Birds

Wilson's Warbler - 19

Orange-crowned Warbler -5

American Redstart -1

Audubon's Yellow-rumped Warbler

Myrtle Yellow-rumped Warbler

Ruby-crowned Kinglet -2

Yellow-bellied Flycatcher -1

Dusky Flycatcher -1

Clay-colored Sparrow-1

Chipping Sparrow -5

House Wren -1

Oregon Junco-1

Lincoln's Sparrow -3

Song Sparrow -1

Green-tailed Towhee -1

Gambel's White-crowned Sparrow-16

Mountain White-crowned Sparrow -1

Spotted Towhee -5

Gray Catbird -1

American Robin -5

Red-shafted Flicker -1

9 Recaptures

Wilson's Warbler -1

Ruby-crowned Kinglet -1

Spotted Towhee -3

Gray Catbird -1

Western Tanager -1

Hermit Thrush -2

Tomorrow is the last banding day for fall season at Chico Basin Ranch. I am very thankful for all the volunteers who contributed to the project this season. Many thanks also to the Birders who have been very helpful with western bird natural history. It is important in understanding bird behaviors and habitat needs for bird conservation. The folks here at Chico have been very accommodating and kind, thank you all for what you do.

Have a good day,

[cobirds] White-throated Sparrow at Ken Caryl

It was fun to see a hatch year White-throated Sparrow in the front yard today, with my little White-crowned flock. This is my earliest of several fall records over 9 seasons. I'm still enjoying several Broad-tailed Hummers in the yard. A friend and I were noting how these late season hummers shift to less frequent use of feeders in these last days.

[cobirds] SW Denver Raptor Movements

While not as focused or scientific as a dedicated Hawk Watch, keeping your eyes to the sky over our Front Range cities can yield some fun results. Aside from resident local COOPER’S and RED-TAILED HAWKs around our neighborhood in southwest Denver (Athmar Park/Huston Park, Denver Co., CO), we picked up two, maybe three instances of migrating raptors in town over the past few days. The first obvious movement came Saturday morning (24 Sept.’22) as we were having coffee on our deck. In a matter of about 15 minutes we had two (2) beautiful “Dark Phase” SWAINSON’S HAWKs, and three (3) AMERICAN KESTRELs all flying fairly low and deliberately south.

The next instance came Sunday evening (25 Sept.’22) at Mile High Stadium during the Broncos game! As we were watching the parachutists drop in during the pre-game festivities, notice an immature PEREGRINE FALCON circling above the stadium as well, hoping the skydivers and falcon noticed each other while giving a knowing wink. In addition to the Peregrine, two (2) different Kestrels also made appearances over the game. While all these falcons, plus a random NORTHERN FLICKER flying through, could be locals, they added some additional interest to a frustratingly dull offense.

Most recently yesterday morning (Tues., 27 Sept.’22), noticed a large raptor circling very high over our house. Ran in to grabbed the binoculars and located another “Dark Phase” Swainson’s Hawk riding a thermal along with someone’s lost mylar balloon. With specs in hand also picked up a Kestrel, Red-tailed Hawk, and an immature SHARP-SHINNED HAWK all riding the same thermal system while slowly coasting south – the balloon must have been a resident as it eventually drifted northwest.

So the moral of this story is, take the time to look up occasionally wherever you are, you might just experience Nature in action.

Good Birding and Go Broncos,

Doug

Observers:

Visitors:
Interestingly not a single person hiking the Hogback Trail today, and only saw a young woman hiking up on my way down.

Weather:
earth.nullschool.net showed light winds from the West becoming South and then SE, while weather.gov predicted 3-5 mph winds starting in the West, becoming North and then NE by the afternoon. From the parking lot going up the trail there was a distinct South wind while at the watch the wind started WSW at Level 5, then became east by 9 AM MST, then there was a stronger Level 3 wind from the East with a lighter Level 2 with from the South at the same time! After the 1st hour I could see both above and below the horizon from NE to SE a grayish brown smog.

Raptor Observations:
On days when there was a perfectly blue sky I wondered whether I was missing migrating hawks, and wanted to come on a day with a lot of cloud cover regardless of the wind to see whether I could find more hawks against the clouds. Today I had excellent broad cumulus cloud cover both north, overhead and south of the watch and was able to test my eyesight by looking at very high local RT which I was able to see against clouds as well as backlit against the blue sky with my naked eye (and polarized sunglasses) â€" so I know I'm not missing large numbers of hawks, i.e. the low daily numbers are because they're not flying past the watch. The first migrants were 2 CH at 8:26 AM MST one behind the other at a moderate distance far to the West and very high, at the limit of binocular ID â€" I required my scope to confirm my suspicion that they were accipiters. I put up my Great Horned Owl decoy which has drawn many species of migrants hawks in the East to buzz it, but none of the migrants nor the locals here seemed interested, nor were any of the passerines bothered by it. Non-migrant raptors: TV 1, RT 2.

Non-raptor Observations:
Townsend's Solitaire 2 all morning singing and calling, White-throated Swift 6, House Finch 2, American Robin 1, Black-billed Magpie 1, Black-capped Chickadee 1. 1 hot air balloon to the NE.

[cobirds] 1st year male Rose-breasted Grosbeak - Denver County

CoBirders,

So it's not a one-day wonder after all... this grosbeak is visiting a tray feeder in the yard where I'm housesitting near Fairmont Cemetary at Quebec and Alameda. The local Cooper's Hawk made a pass through the yard earlier but the grosbeak is still around.

Nice yard bird!

Good Birding,

[cobirds] Bird Conservancy fall fundraiser

Hello all,

I imagine most of you are familiar with the Bird Conservancy of the Rockies. Based in Colorado, it's the region's largest homegrown bird-focused nonprofit. Here are some of the many things that the Bird Conservancy does:

runs some of the largest and most rigorous bird monitoring efforts in North America, throughout the Rocky Mountain and Great Basin regions and from the Northern Great Plains to northern Mexico;
works closely with private landowners, especially agricultural producers, to make sure that those landowners can meet their economic needs while benefiting birds and the environment in general;
spearheads the Central Grasslands Roadmap, an enormous multilateral effort to preserve North American grassland birds, our most threatened cohort of species;
runs banding stations where young children get to see birds up close and personal, often for the first time in their lives;
runs summer camps where young people can grow and share their love of birds and nature.

To help keep this organization strong, I'd like to invite everyone to the Bird Conservancy fall fundraiser on Friday evening, October 14, at the Denver Museum of Nature and Science. For more information and to purchase tickets, see https://bcotr.cbo.io/.

I'm happy to answer questions you may have!

Nathan Pieplow

Bird Conservancy of the Rockies board member

[cobirds] Re: Attn: moderator

I'm not an expert about this but it's my understanding that all of the messages are stored on Google's servers and we all simply view them. The entries are not being downloaded to your computer and they aren't taking up any of your storage.

I occasionally will search through all these entries to find information about a particular species or birding location. Very handy.

So you don't need to delete anything and I don't think you would want to.

Happy to be corrected on this with better information.

[cobirds] Thick-billed Kingbird 9/28

Hi Everyone,

I just had the Thick-billed Kingbird in the cottonwoods next to 1030 Q 3/4 Road in Mack. I heard it call, then saw it fly in close to the road. It stayed from 0730 to 0740. Attached is a less than sterling digiscope photo.

[cobirds] DFO field trips - two added for the coming days

Birders,

I'm posting to let you know of two new field trip opportunities added on the DFO calendar that are coming up real soon.

Sept 30 a short morning birding time at private Ken Caryl Ranch.
Oct 3 an evening chance to watch the White-throated Swifts at their night roost at Deer Creek. They will very soon be gone until spring. The other night we saw an estimated 110 enter the roost.

Also, I have an open trip to the Pueblo Reservoir area this Sunday Oct 2. A nice introduction to birding down there.

Registration and details are here:

DFO's field trip calendar has lots of other great trips open now, or soon to open for registration. DFO field trips are free and open to all. Trips designated "Patch Birding" trips seek to share those locations to help you learn about birding in those spots. Trips designated "Developing Birder" indicate newer birders are very welcome, and a pace that invites questions, and a chance to talk about what we are seeing.

[cobirds] Yard birds - Douglas

Townsend's Solitaires have arrived in our patch to serenade us with their lovely melodic songs. We have probably a dozen or more along our road. Beyond that, we still see an occasional Western Tanager; the males have started to change their head colors from orange to yellow.

Still regular: lots of chickadees (both kinds), 1-2 White-breasted Nuthatches, several flocks of Pygmy Nuthatches, piles of Spotted Towhees (we've counted 15-20 several days). House Finches vary in number, from one or two up to 15 or 20. Scrub-Jays persist, and Blue Jays have arrived to join them (we see them only in the winter months). Gluttonous Turkeys scrape up droppings under our feeders -- from 5 to 15.

We hear crows and ravens, see an occasional Golden Eagle and even less occasionally a Red-tailed Hawk. And just now, a Cooper's Hawk immature.dKestrels moved through last week. So far no Juncos other than Gray-headed.

Hugh Kingery

[cobirds] Bird Conservancy of the Rockies - Barr Banding Report, 9/27/22

We thought the Black-billed Magpie in the 8:40 run would be the bird of the day - big, beautiful, lots of personality, iridescent blues and purple in the sun. But then Colin came back a half hour later with a Northern Harrier, which pretty much blew us away. First ever caught at the banding station, it was chasing breakfast (a mouse) when he was instead flushed into the net. I understand there was considerable running to ensure its capture. (The mouse escaped.)

Otherwise, lots of typical late September species; a total of 58 new birds today:

Northern Harrier 1

Black-billed Magpie 1

House Wren 1

Ruby-crowned Kinglet 1

Hermit Thrush 3

Gray Catbird 1

Orange-crowned Warbler 7

Yellow-rumped Warbler, Audubon's 9

[cobirds] Swainson's hawk & child still around

The juvenile was perched on a phone wire on Oxford between 39th & 49th, gently complaining with its feeble RTHA imitation. After a few minutes as I studied it, a parent swooped in to monitor me. Fair is fair. Then the two took to the air.

[cobirds] West Slope Sept 26th

The Thick-billed Kingbird was still calling a lot and hanging out near Mack, Mesa County yesterday (26 September) at the usual location, from around 9-11am (it was nice to see a few familiar faces), and it sounds like it's still around later too. It seems to be hanging around the house, we could see it with the scope well, sitting on branches in the cottonwoods, it never came close to the road when I was there. Thanks to everyone for continuingly updating sightings about this major Colorado rarity. It was fun to see this species in Colorado, after looking all morning back in 1992 at Waterton Canyon, for the one there the afternoon before.

Another highlight, were found juvenile Sabine's Gulls at the Rifle Airport ponds along I-70 in Garfield County. The fall colors around Aspen and Independence Pass were very nice on the way back. Be alert to delays for road work in Aspen though.

Official Counter	Ajit Antony
Observers:	Liza Antony, Sammy Korengut

Weather:
Earth.nullschool.net had predicted light winds from the West while weather.gov had also predicted light winds from the NW>NE by afternoon but when we got to the watch there was a very brisk Level 6 wind coming from the West with dissipated by the end of the hour, after which there was a Level 3 ? ridge lift coming from the East. A sunny cloudless day with temperature 13-21Â°C humidity 24 â€" 39%, steady barometric pressure around 29.93 mmHg, excellent visibility at 25 km with some haziness in that some of the birds seem to disappear while we were watching them with binoculars.

Raptor Observations:
We planned to get to the watch by 7:30 AM MDT but we were so efficient at making our lunch and coffee the night before that we got there at 7 AM - the 1st time I've ever gone to a hawk watch leaving home in the dark and reaching there just after the sun rose above the Green Mountain. The first migrant was a male AK found by Sammy along the trail at 6:30 AM MST (7:30 AM MDT) seen below the ridge. The 1 and only BW was an adult at 8:35 AM which came in from the North, a binocular bird found by scanning, which streamed to the SSE. Liza looked up BW range and found that while they nest in Western Canada they fly through the central flyway more easterly than Colorado, over Kansas and Oklahoma to Texas to Central America - no wonder they are not very common here. The only other migrant was a female AK at 9:03 AM found to the north and flew just west of the watch, a low bird. Non-migrant raptors: 2 adult GE at 9:36 AM seen immediately south of the top of Mount Morrison but flew West and not counted, RT 1, TV 1.

Non-raptor Observations:
White-throated Swift 1, Townsend's Solitaire 3 even hearing their beautiful songs, Steller's Jay 2, Blue Jay 3, American Crow 1, Common Raven 3, Woodhouse's Scrub-Jay 1, House Finch 1, American Robin 2, Black-billed Magpie 1, Canada Goose 1, Mountain Chickadee 2, Black-capped Chickadee 2. 3 hot air balloons to the NE and one to the SE which didn't lift very high at all. 1 hang glider to the NNW.
