[cobirds] Piratic Flycatcher: Joey Kellner's 500th species in Colorado

Hi all,

An article in today's Denver Post celebrates the Yuma County Piratic Flycatcher found by Dan Maynard as the 523rd species ever to be seen in Colorado, and Joey Kellner's 500th state bird.


Huge congratulations to Joey on this enormous milestone. As far as I can tell from a quick stroll around eBird, a single person seeing 500 species has only been accomplished in 5 other states: California, Arizona, New Mexico, Texas, and Florida, although it's possible that someone's done it in Oregon as well, as the top public eBird list there is 495. 

If you needed more evidence that we live in one of the finest US states for birding, there it is.

(Note: it's possible Duane Nelson has also seen 500 species in Colorado, but Duane doesn't officially keep track of his number, according to what he told me when I ran into him at the Phainopepla in Baca County last month ðŸ™‚).

Observers: Liza Antony



Visitors:
Ben Fassett from Arvada who read our eBird reports, had never seen a Broad-winged Hawk and came up for an hour with his binoculars and camera. He was able to see the Swainson's Hawk in migration and got good images of an AK in flight. Bob Sargeant a biologist and ornithologist from the Georgia Department of Natural Resources came to the watch for an hour. He had also found the Mount Zion Hawk Watch hotspot on eBird.

Weather:
Severe brown haze over Denver going up 5� above ground level. Minimal cloud cover at the start going up to 30% maximum, light winds from the ESE, visibility 6 km gradually increasing to 20 km with the haze persisting.

Raptor Observations:
The first migrant was at 9:45 a.m. mdte and was an AK in the Kestrel Channel. Between 10: 20 a.m. and 10:28 a.m. we had 7 Swainson's Hawk fly low over the Table Mountains migrating through the gap between Green Mountain and Lookout Mountain. A single adult BW overhead at 12:29 p.m. 2 Merlin flying fairly close to the east.

Non-raptor Observations:
The 2 paragliders at 12:15 p.m. MDT had no lift, but the 2 at 1:00 p.m. had moderate lift.

Predictions:
A chance of showers, with thunderstorms also possible after 3pm. Mostly cloudy, with a high near 77. Light and variable wind becoming northeast 5 to 7 mph in the afternoon. Chance of precipitation is 40%

[cobirds] The Buena Vista Shuffle

Clark's Nutcracker getting a drink at Buena Vista River Park on the Arkansas River. 
Clark's Nutcracker River Park 3 signed copy.jpg



All:
        For the 8th, 9th, and 10th of September.  Late post.   This is for the Buena Vista Colorado area.   
      For those birders familiar with Buena Vista, you know that its "Covid Rich".   And two noteworthy things about it are that hundreds of mule deer pile into town in the winter, as well as pinyon jays that attack bird feeders with vigor.  

Clark's Nutcracker - over 60, most concentrated at the Buena Vista River Park trail(s) - easy to observe and photograph.  This part of the Arkansas River must be like paradise for Nutcrackers, as one side is open pinyon forest sloping down the river, which is thick with narrow-leaf cottonwoods, willow, oak, rabbitbrush, three leaf sumac, and other deciduous shrubs.  Their numbers seem to be increasing along the river each year.  

Pinyon Jay - over 100 seen at the Collegiate Peaks Overlook off of route 285 (state parks pass required).  This is one of best places in Colorado to watch for Pinyon Jays.  

Scrub Jay - about 6 at the River Park Trail and a couple more in town. 

Stellar's Jay - about 30 along the River Park Trail, and more up the Cotton Pass Road.  

Gray Jay - 2 - near Little Ptarmigan Lake \ Ptarmigan Lake Trail.  A grueling hike that I would not recommend unless you are in good shape. 

Black Billed Magpie - scant, only 2 heard in town. 

Common Raven - 2 at Cottonwood Pass (12,126 feet).  

American Crow - about 40 in and around town.  

Other birds and wildlife.  
Cottonwood Pass = CP
Cottonwood Pass Road = CR
Cottonwood Hot Springs = CS
Buena Vista River Trail - BVT
Buena Vista (town proper) - BV
Ptarmigan Lake(s) Trail - PL
Continental Divide Trail - CD

Mountain Chickadee - 100 +   CR, PL
Red Breasted Nuthatch - 15  CR, CS, PL
Pygmy Nuthatch - 12 - BV, BVT
White Breasted Nuthatch - 2  - BV
Black Capped Chickadee - 6 - BVT
Gray Headed Junco - hundreds, even above Cottonwood Pass along the Continental Divide Trail.  CD, CP, CR, BVT, BV, PL
House Wren - only 1 seen at BVT
Chipping Sparrow - about 50 including migratory groups above 12,000 feet foraging in the tundra.  CD, BV, BVT, PL, CP
Ruby Crowned Kinglet - 12 - along PL 
Broad Tailed Hummingbird - 2 at CS and 2 in BV
Wilson's Warbler - only a couple - PL and BVT
Audubon's Warbler - 11 - BV, BVT, CR
MacGillivray's Warbler - 1 at CL
White Crowned Sparrow - 12 - at CD and CP
House Sparrow - few in numbers, only 6 - BVT
Bushtit - 20 - BV, BVT
Belted Kingfisher - 1 - flying along CR
Green Tailed Towhee - 6 - at CL and BVT - foraging
Townsend's Solitaire - 6 - BVT - eating juniper berries
American Robin - 60 + most in higher mixed evergreen forests.  BVT, PL, CP, CR
Mallard - 40 in ponds and lakes, most at CL
Common Grackle - 200 - two large flocks at BV
Eurasian Collared Dove - only 4 in BV
Mountain Bluebird - 2 along CD above 12,000 feet foraging 
Plumbeous Vireo - 1 - at BVT in a ponderosa pine
American Pipit - 20+ foraging groups along CD in the tundra
Red Crossbill - 2 - the only ones seen - at BVT flyover \ calling
Northern Flicker - 6 - BVT, PL, CR
Downy Woodpecker - 2 - CR and BV

Pika - 4 - PL trail
Pine Squirrel - hundreds gathering Doug fir cones and spruce cones in mixed conifer forests up to tree line. 
Mule Deer - 25 - BV, CR - early morning was the worst, as they wandered right out onto roads around corners while driving. 
Chipmunk spp:  100+  -  in mixed conifer habitats and surprisingly lots of them foraging above 12,000 along the CDT. 

Conspicuously absent:  starlings, house finches, and raptors of any kind.  

The two great things near and in Buena Vista are the numerous hot springs, and the cool plunge pools along the Arkansas River Trail - which I took advantage of.  Cottonwood Hot Springs now has a cold plunge right into cold numbing Cottonwood Creek.  Great after a hot day of hiking and birding.  Wim Hof eat your heart out.  

Happy fall, 
John T (Tumasonis)

[cobirds] ZONE-TAILED HAWK very close to Baca County

I saw a Zone-tailed Hawk in Oklahoma maybe within a mile of Colorado in Oklahoma this morning.  One was photographed this month at Carrizo Canyon in Baca County, today’s bird wasn’t far away.  Maybe Picture Canyon is also not too far away.

Observers: Liza Antony



Visitors:
Michael K. of South Platt Park who was a volunteer counter at Dinosaur Ridge Hawk Watch from 2011 to 2013 had seen our reports on COBirds and came up for about an hour. A couple asked whether we were birding, and I explained. She wanted to know how many raptors we had seen, and I said 61, and she said I'm jealous. To console her, I said that they were quite far and she wouldn't have been able to see most of them without binoculars.

Weather:
Denver was completely hazy today due to 10� inversion layer over the horizon. There were cumulus clouds both to the east as well as to the west going from 45% to 25% to 60% and back to 20%. Cool and pleasant all day.

Raptor Observations:
Another great Swainson's Hawk day, which started with Liza finding 3 buteos overhead and a little to the north of us, which she promptly identified as SW - 2 juveniles with light heads and an adult with a dark head. As they streamed toward the SW, remembering what we did with BW in New York, I looked ahead of them and sure enough there were more. In the next 10 minutes we had 47 SW streaming and kettling! As of today we have counted 176 SW for the season which is the highest compared to all the spring season counts since 1990 - 99 more SW than the highest seasonal total of 77 counted in 2023! This may be a fall migration phenomenon. An adult female AK flew straight at us at eye level from the north and veered only 20 ft from us, We had 3 single BW, 2 "local TV" I found over North Table Mountain which when they came closer Liza correctly identified as adult GE, one of which was a non-migrant and dove from a great height into Clear Creek Canyon and then flew NW, the other was a migrant at 2:02 p.m. MDT which had a molting/missing left inner primary. A migrant CH dove onto a migrant AK near it and then both continued migrating South. Non-migrant raptors: GE 2 one of which glided at eye level to the east of us seeming to be a migrant, dropped below the top of Lookout Mountain and then flew back out to the NE, RT 3, TV 5.

Non-raptor Observations:
2 tandem paragliders had no lift at 10:30 a.m. DST, not even reaching our height, while at 12:15 p.m. 3 paragliders had excellent lift going really high, going far to the North where we could just about see them without binoculars. The Soaring Forecast of the NWS had good lift at 11 feet per second, and height of thermals at 8,684 ft AGL.

Predictions:
A slight chance of showers between noon. Mostly sunny, with a high near 78. Calm wind becoming east 5 to 7 mph. Chance of precipitation is 20%. The winds aloft are predicted to be light coming from the SW to the West.
