[cobirds] Park County 9/28

This day I focused on roads generally south of Eleven Mile Canyon, also checking Lake George, Eleven Mile Reservoir and Spinney Mountain Reservoir. 

Lake George did have a Sora and 2 Common Yellowthroats, both probably on the late side of the spectrum for Park Co. Also an amalgamation of black birds in the cattails included about 110 Eur. Starlings, a high count for the county, I think. Who ever takes a moment to delight in such a factoid?

Coverage of CR 61, 98 and NF Roads 244 and 393 had some rather birdy areas, with flocks of bluebirds widespread, lots of Audubon's Warblers in association with those, and locally large flocks of Dark-eyed Juncos (Gray-headed, Pink-sided quite common, Oregon uncommon, and 1 Slate-colored). Red Crossbill has finally largely abandoned the pine forests of this region of Park, with just a couple Type 2 birds noted, making for my least crossbill-filled day in Park in 1.5 years. Uncommon to tardy migrants for the date and area included 1 Williamson's Sapsucker, 3 Plumbeous Vireos, 1 Gray Catbird, 5 Sage Thrashers, 2 Townsend's Warblers, 1 MacGilivray's Warbler, and 9 Green-tailed Towhees. Among a moderate sprinkling of gray-headed Orange-crowned Warblers.I also saw one showing characters of the lutescens form (CR 98). A tardy for Park (?) Band-tailed Pigeon was flying near CR 98 x Road 244. A Lewis's Woodpecker was in the forest at Road 244, and 3 Evening Grosbeaks. A Grasshopper Sparrow along CR 98 was unexpected appearing at a small wet grassy swale that bordered a willow patch along a minor stream. It was sort of out of context in an area lacking in moderate or better grassy areas, and threw me for a bit as it perched up in a willow. Not far off there was an Am. Three-toed Woodpecker...

Eleven Mile and Spinney reservoirs were decidedly dull, despite an increasing variety of waterfowl and burgeoning numbers of Am. Coots (about 10,800 between both lakes). Eleven Mile did have a tight flock of 5 Horned Grebes and 3 Red-necked Phalaropes (plus 2 too far to ID). The most interesting observation at Eleven Mile was actually of a Mountain Chickadee out of place in an isolated willow patch along the wide open lake shore at Howbert Point. Usually the only passerines in this area are Brewer's Blackbirds, Horned Larks, Vesper Sparrows and crows. I watched as it launched confidently from the willows for a solo flight over the big lake toward the opposite shore, just a little bit like Limbergh or maybe Earhart. Another amusing sighting there was a red fox intent on reaching a tiny islet (just a rock, really) off of the lake's largest island. It waded out gingerly, careful to hold its tail above the water, until there was nothing for it and it had to swim with tail immersed. A party of Gadwalls trailed close behind in a line. I'm not sure why the fox wanted to reach the rock, which seemed to be just a cormorant white-washed bump with little to encourage a visit, but having gotten there it nosed about and considered its next move.

The best bird of the day came at night. Well after sunset a Barn Owl flew over CR 59 north of Spinney Mountain Reservoir, and then I heard the bird calling in the distance over the pastures.

[cobirds] Chico Banding Station Update 9/30

This morning started out so slow we were worried that we wouldn't hit double digits! Several birds were caught at 830am, however, and there continued to be a steady trickle of birds throughout the later morning, thanks mostly to flocks of Juncos.

Also caught today was the first pileolata subspecies of the Wilson's Warbler. This season has brought hundreds of the chryseola subspecies, which are the first group of Wilson's Warblers to migrate, and have recently been discovered to be on the decline. The pileolata subspecies, which are a less yellow-orangey version of the Wilson's Warbler we've been seeing, was a great catch for the morning, and an interesting bird to show the 2nd graders that visited today from Pikes Peak School of Expeditionary Learning. The group also enjoyed seeing the noisy after hatch-year robin caught at the end of the day.

The tally for today:

1 Hermit Thrush
1 American Robin
2 Orange-crowned Warbler
4 Wilson's Warbler
1 Lincoln's Sparrow
1 Gambel's White-crowned Sparrow
13 Oregon Dark-eyed Junco

[cobirds] Barr Banding Station Update, 9/30/15

FLICKERS!  Five of them in 4 different nets (in close proximity to each other), all at the same time. One male and four females.  Raised a few practical questions ("Can someone find me another really big bird bag?"), but mostly they created an incredible high for the experienced team of Bird Conservancy staff and volunteers that found unadulterated joy in getting them out of the nets, banded, processed, photographed and shown off to an appreciative group of Fort Morgan high school students.  They really are lovely birds with big personalities.  

Otherwise, a nice fall morning, dominated by Orange-crowneds and White-crowneds:

Red-shafted Flicker 4 (the 5th was a recapture, banded last week)
House Wren 2
Ruby-crowned Kinglet 1
Hermit Thrush 4
Gray Catbird 1
Orange-crowned Warbler 7
Yellow-rumped Warbler, Audubon's 2
Song Sparrow 2
White-crowned Sparrow, Gambel's 9
Dark-eyed Junco, Oregon 2

We are CLOSED TOMORROW, 10/1. We are open 6 days per week, weather permitting, for 1 1/2 more weeks (through Sunday, October 11). We are opening nets at 6:30, and run until noon or whenever it gets too hot or too windy or too whatever. School groups arrive about 9:30 a.m. most weekdays.

[cobirds] Hamilton Reservoir (Larimer) Overlook Closed

FYI, I tried to check Hamilton Reservoir today for Sabine's Gull or whatever, but found the gate locked to the Observation Overlook.  I called the plant on the phone at the beginning of the dam to see if I could walk in with a scope and the security guy told me it was closed for construction "until around Thanksgiving".

On the same subject, I appreciate the prompt response received from the Ranger regarding Crow Valley.  I guess it is good news for the time being.

[cobirds] Ken Caryl Valley 9/29

An Orange-crowned Warbler showing characters of the bright lutescens form and a tardy Western Tanager were along Massey Draw near my home. Townsend's Solitaires were on the move and numerous. I tallied 24 of them at several spots this morning, including 7 flying over my home and 12 in a limited area of the vale between the Dakota and Lyons hogbacks. Bluebirds (the vast majority Mountain) were also on the move. They were abundant in the vale between the hogbacks. In the area north of Massey Draw I tallied a wonderful 378 Mountain Bluebirds. Nearly 150 were foraging, and a steady progression of flocks flew over. 18 Rock Wrens were in this same area.

[cobirds] Chico Banding Station Update 9/29

Today was a record slow day for the station this season, with only 13 new birds banded. Thankfully, we were able to show the fifty 1st graders who visited a few different species, including an Ovenbird! 

The final tally for today:

5 Ruby-crowned Kinglet
2 Hermit Thrush
1 Orange-crowned Warbler
1 Ovenbird
2 Wilson's Warbler
1 Spotted Towhee
1 Song Sparrow

Yesterday morning we caught a hatch-year male Sharp-shinned Hawk as he was hunting in the net lanes, and then caught him again in the afternoon! Visiting students from Colorado College were lucky enough to get a great look at a beautiful bird. We also caught a hatch-year Curve-billed Thrasher while the students were visiting, which was a treat for all of us at the banding station. We had 40 birds overall, most of these from the last net run, when we happened to catch a few flocks of sparrows. Not a busy week, but we had some fantastic birds.

[cobirds] Barr Banding Station Update, 9/29/15

My thought when I woke up this morning at 4:30 and realized it had rained overnight was "Oh boy, birds today!"  Ha.  The first run (which started a bit late, because it was still drizzling when we arrived) showed a slight promise, but then dwindled to nothing.  It got windy by mid-morning, but that really made little difference - we already weren't catching anything.  The 6 White-crowned Sparrows were caught at the feeder nets at the Nature Center.  The one excitement and ID challenge of the day was a young Swamp Sparrow.  We don't catch them very often, but we did have one last year on 10/2.  Here's the breakdown of the 17 new plus 1 return:

Black-capped Chickadee 1 return, banded 2013
Ruby-crowned Kinglet 1
Hermit Thrush 1
Orange-crowned Warbler 7
Yellow-rumped Warbler, Aududon's 1
Swamp Sparrow 1
White-crowned Sparrow, Gambel's 6

We are open 6 days per week, weather permitting, for 1 1/2  more weeks (through Sunday, October 11). This week we will be closed on Thursday, 10/1. We are opening nets at 6:30, and run until noon or whenever it gets too hot or too windy or too whatever. School groups arrive about 9:30 a.m. most weekdays.

re: [cobirds] Spotted Towhee & Bushtits in west Centennial, Arapahoe County

I have spotted towhees (1-2, in migration up to 4) here (including today) 9 months a year or more.
Still have two western scrub-jays, here for the past 9 days.
Haven't seen bushtits here for two-three months but expect them to be wandering back.
Cooper's hawk still perches on my feeder every other day or so.

Hello Fellow Birders,
 
   Bushtits are usually year-round denizens of my neighborhood near Holly & Arapahoe, but they were missing in action all summer till about a week ago when I heard a good-sized flock moving through the area.  Today they finally deigned to stop by my yard and get a little suet.
 
   A single Spotted Towhee also visited my yard today.  I typically see one each Fall, though usually much later than this.  If the past forecasts the future this bird will stick around a few days then be gone.

[cobirds] White-throated Sparrow, Boulder, 9/29

This morning at about 8:30, while watching the N Cardinal at my feeders, I had a very brief visit from a tan-striped White-throated Sparrow--too quick for photos unfortunately. Yesterday I had a couple of White-crowned Sparrows and Orange-crowned Warblers.

[cobirds] Sandhill Cranes, Boulder County, Sept. 28

Hello, Birders. Yesterday evening, Mon. Sept. 28, at 5:38 p.m., a car-full of Floyds (Hannah, Andrew, Edwin, Mary, and Yours Truly) saw exactly 20 sandhill cranes flying north low over South Boulder Road, Boulder County, near Cherryvale Road. They seemed to be on "initial descent," if you will, to some nearby spot. Perhaps Baseline Rez.

[cobirds] Thanks, Todd!

Cobirders,

 

I wanted to extend my thanks,  on behalf of the entire CFO Board of Directors,  to Todd Deininger for his admirable leadership as Cobirds Moderator over the past many years.  Todd has worked hard moderating Cobirds as list manager for at least 5 years now—since 2011 or earlier.  Over that time Cobirds has continued as one of the top internet birding services in the country with somewhere around 1,500 subscribers.  Herding that many cats is not easy!

 

Historical records of internet interactions are surprisingly hard to track down.  I can determine that Cobirds turned 20 years old a few months ago because I can find an email with directions to join from June 1995.  Cobirds was one of the very first state-wide listserves springing from the initial WWW site, BIRDCHAT (yes it was all caps) in the mid-1990s.  The late Wally Collins, Alan Versaw and I saw this path to the future of birding and set up Cobirds at that time and it became a model of internet birding. 

 

At first it was a listserve through the University of Colorado Boulder.  (As an aside, I can point out that here at CU Boulder we have a faculty member, Lori Emerson, who is world renowned as an expert in Media Archeology—something that we wish we had been more careful about years down the road!)  In the early 2000s, Alan and I passed on Cobirds to the Colorado Field Ornithologists where the service was managed by Rachel Hopper until the very late 2000s.  That is about when Todd took over.

 

Todd is stepping down at this time in order to enjoy more time in the field.  CFO President, Doug Faulkner as well as board members Lisa Edwards and Mark Peterson will try to handle duties until a new moderator is named.  But I would like to really pay due respects to Todd for the services he has rendered.  He has been like a referee whose excellent work you never notice while it is taking place.

 

Thanks, Todd

[cobirds] Barr Banding Station Update, 9/28/15

After our rather pathetic Sunday, it was nice to return to our leisurely fall banding of last week, with 37 new birds and a great variety of species.  Star of the day was a Sage Thrasher (we caught one last year as well; the last one before that was before 2005).  Here's the breakdown of the 37 new birds:

Dusky Flycatcher 1 (Flycatchers have been in very short supply this year, and this was the first of any species in 2 weeks)
Ruby-crowned Kinglet 1
Hermit Thrush 2
Gray Catbird 1
Sage Thrasher 1
Orange-crowned Warbler 4
Yellow-rumped Warbler, Audubon's 4
Wilson's Warbler 5
Spotted Towhee 1
Chipping Sparrow 3
Clay-colored Sparrow 2
Song Sparrow 2
White-crowned Sparrow, Gambel's 8
Dark-eyed Junco 2

We are open 6 days per week, weather permitting, for 2 more weeks (through Sunday, October 11). This week we will be closed on Thursday, 10/1. We are opening nets at 6:30, and run until noon or whenever it gets too hot or too
windy or too whatever. School groups arrive about 9:30 a.m. most weekdays.

[cobirds] Snowy Egrets and other ardeids at Greenlee Preserve, Boulder County

Hi, all.

Just a quick note here to let folks know that Greenlee "Reservoir" and adjacent Waneka "Lake" are seriously infested right now with seriously photogenic Snowy Egrets and Great Blue Herons and a few Black-crowned Night-Herons. You might reasonably infer that they're attracted by hackberry psyllids, but, no, it seems that bullfrogs are the draw. With both bodies of water being drawn down (perhaps for diversion to Mars?), the bullfrogs are easy pickings.

Despite great-seeming conditions, there aren't many shorebirds. But ducks--Green-winged, Blue-winged, and a few Cinnamon teal, and Wood Ducks--are plentiful. Eurasian Collared-Doves galore, and a few African Collared-Doves hanging on. The Bushtits are catch-'em-if-you-can. Will the Barn Swallows ever leave? Well, I think the Swainson's Hawks are finally gone. The Great Horned Owls are marvelously vocal, dawn and dusk.

Oh, and I saw and heard a Rock Wren there the other day! My first at the preserve since my pre-eBird days, so my 232nd species for the site. A migrant, of course, and he went straight for the rock pile on the northeast corner of Waneka Lake. Figures. Exact same place that I saw one in May 2006, pre-eBird.

[cobirds] Re: Closure of Crow Valley Campground by the USFS?

Answer from definitive FS source ...

Hi Gary,

 

Just wanted to let you know that there is no intention to close the Crow Valley campground at this time. While the Forest Service across the nation is suffering from budget restraints and trying to determine what size of a recreational program will fit in the future, any decisions to close sites would require much additional thoughts and analysis. We have not done anything like that. Even should we enter into such a process, one point that would be discussed and analyzed would be the distance to other available campgrounds in the area. Crow Valley being the only one for many miles has that going for it  even in a worst case scenario. I just wanted to let you know that we have not even gotten to that stage of the game yet so, there is really no truth to the rumors you have heard. Are we short money –yes. Are we wondering how to fix it – yes. Do we know what that fix looks like – not at the present time.

 

Stop in and see me if you have any more concerns. I understand you live in Nunn.

Rumors abound about the possible permanent closure following this season of Crow Valley Campground on the Pawnee National Grasslands near Briggsdale.  Any one with concrete knowledge about this subject is encouraged to comment (preferably on this forum, not Facebook) regarding the rumor.  If the rumor is true, is the property being retained by the USDA and simply closed to camping but open to other public access, transferred to another governmental agency or private entity, or what?  Is it too late to comment on the changes, whatever they might be?  Who do we write to if access for the purpose of birding is to be ended?

[cobirds] Common Nighthawk & Possible Philadelphia Vireo - Cheesman & Gardens (Denver)

I took my dog for a walk in Little Cheesman around dawn. We were briefly joined by two Common Nighthawk, which flew low, this time over the western (Williams St.) side of the park. They disappeared in that direction.

Later in the morning, I went to the Gardens, which were birdy with an assortment of sparrow. Near the end of my time there, I came across a vireo foraging in a Western River Birch, near the southern edge of Gates Montane Garden pond (point 20 on the map). (Heavily cropped photos are here. Feel free to email if you'd like the originals.) The bird took off in the direction of Cheesman, but I failed to relocate it. The bird looks a lot like the one Chris Rurik and I encountered on the 23rd. Lots of yellow wash and dark lores.  

Apologies, in advance, if this isn't a philly and input, as always, is appreciated.

[cobirds] Common Nighthawk - Little Cheesman - Denver

I took my dog Iggy for an evening walk in Cheesman, hoping to see the sapsucker before the sunset. I didn't. On our way out of main Cheesman, Iggy and I dawdled, hoping to spot nighthawk. We didn't. We gave up as clouds arrived from the west and evening from the other side. 

We took our time getting back to our car, which was parked near 7th and High St in "Little Cheesman." And I took my time leaving our parking spot, reading a few urgent, unexpected, but well-timed work emails from the driver's seat. Those emails held me up long enough for a nighthawk to swoop by, low into Little Cheesman. I told Iggy I'd be right back, hopped out, then stood in the field as three of the birds swept through. (I believe there were three. One would come by, I'd watch it, turn and see two. But perhaps the first joined a second in the time when I lost track of it.)  One came by at eye level, an arm's length or so away. 

This all happened around 7:15-7:25 PM. The birds came in from the east (approx. Race St.). I observed them from the High St side of the park, midway between 7th and 8th. I don't know that they make a habit of visiting Little Cheesman nightly, but it seems worth investigating. 

Interestingly, on June 8, I saw a nighthawk fly out, then back into, Race St between 7th and 8th. This happened once or twice. The bird didn't make any territorial displays -- just disappeared out of view behind the houses east of Little Cheesman.
