Re: [cobirds] Re: First bird of the year . .

[Patrick O'Driscoll]

I'd like to say mine was the handsome Krider's Red-tailed Hawk that our
Denver Urban CBC group found perched in a big tree as we gathered at about
7:45 a.m. New Year's at the First Creek @ DEN Open Space trailhead out near
the airport.
But I'd already been up since zero-dark-thirty to check out waterfowl at
several nearby ponds.
My first birds that day:
A raft of five Common Goldeneyes (all males).
They were in a pool on the mostly frozen Emerald Strand, an L-shaped finger
of water in Denver's Gateway Park area (office parks/apartments/hotels)
west of the Peñs Boulevard access highway and south of the Arsenal.

Re: [cobirds] Marauding Magpies and Bad Boy Blue Jays in west Centennial, Arapahoe County

[Patrick O'Driscoll]

Hey Kevin --
Here in east-central Denver, a mile SE of Denver City Park and 2 doors down
from East Colfax, we had a flock of 45 magpies foraging up and down my
block all day two weeks ago, and about 4 of them have continued to visit in
or around my yard since then.
I assume many of them came from City Park, where summer dozens of parents
and offspring (many big nests in old trees) have suddenly gone scarce.

Meanwhile, the one or two Blue Jays that have visited my yard on and off
over the past month suddenly became 7 yesterday, and they and the magpies
spent a lot of time jockeying for my suet feeder, seed platform and peanut
wreath then and again today.
A regular pair of flickers, 3-6 chickadees, two collared doves and
several House Finches have paid their feeder visits whenever they can,
between scrums by the corvids.

Speaking of which, we always have a few crows around; lately there's a
noisy early-morning meetup of 6-16 atop a tall cottonwood down the back
alley.
Come winter, we'll have hundreds flying west overhead near sunset, heading
for roosts close to and sometimes IN downtown.
And some days from winter into spring, I'll get as many as 30-40 right in
the yard earlier in the day, usually aiming for the peanuts.

Re: [cobirds] "millers"

[Patrick O'Driscoll]

Thanks for your miller time enlightenment, David.
This may explain some rather erratic (to me) behavior I noticed the other
day in a very uncommon visitor to my east-central Denver stretch of busy
East Colfax Avenue -- a male Lark Bunting.
I thought he was just off his game and out of place, maybe confounded by
the unfamiliar urban setting.
Your guidance suggests his skittering around my alley and in and out from
beneath vehicles in the used car lot two doors up may have been in pursuit
of our noticeable local population of the moths.

Re: [cobirds] Red Headed Woodpecker

[Patrick O'Driscoll]

Anecdotally, that year 2020 spike on David's eBird graph included a number
of Front Range sightings in late spring-into-summer, including in central
Denver's Heron Pond Natural Area, in a since-closed-access part of Box
Elder Creek on the eastern outskirts of Denver International Airport, and
in JeffCo's Coal Creek Open Space, among others.

Re: [cobirds] Help with NM oriole ID

[Patrick O'Driscoll]

Connie:
Just comparing it with the song on the Sibley's app, it sounds a lot like
Scott's Oriole, which has similar black-over-yellow plumage, too.
Scott's Oriole's summer range would include that part of NM as well,
according to Sibley's.
Audubon's call and song (again, on the Sibley's app) are more whistley than
this, too -- and its usual range is far more limited (far south Texas).
Either way, a nice bird!

Re: [cobirds] cold fallout fun in the yard

[Patrick O'Driscoll]

I, too, had a White-throated Sparrow, before sunrise Thursday, with my
usual juncos (Slated-coloreds, Pink-sideds, Oregons and a single
White-winged). The White-throated was a new yardbird for me here in
Denver's Hale neighborhood.
But the Cassin's Finch(es) were no-shows, as well (singles a couple of
times and half a dozen one day last week).
No grosbeaks here, but a single Cedar Waxwing this morning (not the first
this winter).

Happy Xmas birding,

Re: [cobirds] Broomfield \ Geese \ Raptors \ Virus

[Patrick O'Driscoll]

In Denver City Park, with about 4,500 mostly Cackling Geese overwintering
between Ferril and Duck lakes and the City Park Golf Course fairways, there
are what appear to be two dead Canada/Cackling Geese -- one in ice toward
the back right corner of Duck Lake, and the other in ice in the west part
of Ferril Lake, between the pavilion bandstand and the big central lake
fountain. (Both lakes are still more open than iced over.)
Goose carcasses in winter are not common. but not unheard of, either --
like these, rather stray, or one at a time.
Still, I'm watching the flocks for any additional casualties that could
suggest or indicate something like flu.
The bulk of the flocks arrived in early November, but we still get new
birds -- witness three Greater White-fronteds and 1-2 Snows in the past
week or so, in addition to four Snow Geese (a pair of immature siblings,
and two adults also traveling together) that have been in the park for a
couple of weeks (the adults) and about a month (the younger ones).

Re: [cobirds] Abridged summary of cobirds@googlegroups.com - 4 updates in3 topics

[Patrick O'Driscoll]

Same here -- two Cassin's Finches among dozens of hungry juncos, House
Finches and House Sparrows, and a few chickadees and towhees.
Cassin's is a new yard bird for me here in east-central Denver.
About 10 days ago, we had a first eBird record for Cassin's in Denver City
Park, a mile west.
Seems like there's a Cassin's irruption of sorts going on along the Front
Range this late autumn.

[cobirds] DFO field trip Tuesday, Nov. 29 to Denver City Park CANCELED

[Patrick O'Driscoll]

Per Denver Field Ornithologists field trip policy, this is to post notice
that because of impending cold/windy/snowy weather and field trip leader
illness, the DFO outing scheduled for Denver City Park on Tuesday, Nov. 29
has been canceled.

But in case you're interested in joining us in 3 weeks to sort through
thousands of geese and enjoy the rest of the park's winter residents,
there's another DFO trip scheduled in Denver City Park for Sunday, Dec. 18.
Read about it on the DFO Field Trips webpage at
https://dfobirds.org/FieldTrips/UpcomingTrips.aspx.


Good birding,

Re: [cobirds] Lake McIntosh 11/20

[Patrick O'Driscoll]

Mark, I was surprised at such behavior earlier this fall as well.
I live near Denver City Park, where one day last month I found a juniper
tree with as many as 10 of them singing loudly, chasing each other in and
out and around the tree, and generally raising a ruckus.
After checking Cornell's Birds of the World, I found out why:
Townsend's Solitaires, which breed in the high country and spend winter
down here among us, are highly territorial in winter, seeking to protect
berry-laden junipers and other food-source trees from other solitaires and,
indeed, from other berry eaters like American Robins and Cedar Waxwings.
(I saw a Townsend's in City Park last month chasing individuals of both
those species away from its territory near the Denver Museum of Nature +
Science.)
It might be coincidental, but over here in east-central Denver, I'm
seeing more of them this fall than ever before.
I counted 5 this morning in City Park, and yesterday a pair chased each
other around a curbside maple tree outside my house just off East Colfax
Avenue.
As for that mirror encounter you reported, I also saw one 10 days ago in
the City Park West neighborhood about 3 blocks west of the park, flying
repeatedly from the ground up into a front window of a house, trying to
attack its own reflection.
So, it appears your Townsend's was behaving normally for this busy time.

Good birding,

Patrick O'Driscoll

[cobirds] Swallows + tanagers @ Denver City Park

[Patrick O'Driscoll]

After an uncommonly quiet spring migration thusfar in Denver City Park, the
weekend snowstorm stirred things up a little.

Saturday morning found at least 60 Violet-green Swallows fluttering low and
slow over the surface of Duck Lake, catching breakfast. The most of those
there in previous memory was maybe 10.

Over in the "pinetum" grove of conifers beneath the south wall of the
Denver Museum of Nature + Science, the season's first Western Tanagers,
four males, picked through spruces and junipers.

Re: [cobirds] Massive murder of crows, Denver 1/15

[Patrick O'Driscoll]

Yes, most winter days near sunset, good numbers of those crows fly in from
the east side of Denver (and beyond?). They often fly directly over my
house just off East Colfax, about 4 miles east of the Capitol.
One recent evening I counted 805, another 529, all flying west to their
winter night roosts.
Their flyovers coincide roughly with official sunset and go on 15-20
minutes.
I had been wondering where they were ending up.

Coincidentally, I was recycling last week through a pile of bird-related
magazines and came upon a fascinating piece from a year or two ago about a
massive winter roost in Lawrence, MA, with more than 15,000 American and
Fish Crows nightly. They roost in various banks of trees around the area
but also "stage" before the roosting in parking lots of former industrial
mills, as well as on the frozen Merrimack River.
I can't find that article now, but a story in the local daily paper from
the same time went into considerable detail:
https://www.eagletribune.com/news/merrimack_valley/visit-of-15-000-crows-to-lawrence-fascinates-researchers-bird-enthusiasts/article_5624715a-cb01-5f0f-9ee1-e05e8dedc247.html

Re: [cobirds] Barrow's Goldeneye - South Platte River, Denver

Travis's sighting on Friday was in Denver County in the Overland Pond
Park/Overland Golf Course reach of the South Platte @ West Florida Avenue.
He reported it on this eBird checklist (

Last winter, a male Barrow's spent weeks at the same location, hanging out
mostly with one of the female Common Goldeneye there.

Re: [cobirds] Re: History - Old bird checklists

[Patrick O'Driscoll]

I wholeheartedly agree with Chuck.
Pre-eBird paper lists are important artifacts of our birding history,
especially as so much of our recordkeeping has shifted to digital.
And Jeff, your remarks are a great reminder for all of us to archive our
earlier lists on eBird.
Those of us eBirders who regularly visit Denver City Park know something
about this.
Sometime after the Cornell Lab invented eBird, a prominent Colorado birder
who visited City Park regularly in his youth transferred all of his written
birding lists from there into the database.
Between 1947 and 1950, young Hugh Kingery recorded hundreds of visits  and
sightings in the park.
eBird tells us now that Hugh was responsible for the first 80 species
sightings in Denver City Park, all in that period. (More than three decades
later, in 1987, he added two more first sightings.)
Hugh's 320 "Denver City Park" eBird lists far outnumber those of the rest
of us.
His is a shining example of the importance of saving all of our sightings
to the Cornell Lab's brilliant invention.

Good eBirding!

[cobirds] Mississippi Kites in Denver’s Clayton neighborhood

[Patrick O'Driscoll]

Not one, not two, but three continuing Mississippi Kites seen Saturday
morning along 33rd Avenue between Columbine and Clayton streets. After some
initial confusion about IDs, those of us there (including Meg Reck, Bez B.,
Doug Schoch and others) believe there are two adults and one juvenile. Also
around are at least 10 other species, including a pair of Downy WP, Blue
Jays, Western Wood-Pewee, nuthatches, etc.  , making for a nice Saturday
outing to go with the Denver County rarities.

Good kiting!

Re: [cobirds] Black Phoebe back at Wingate South Park, JeffCo

[Patrick O'Driscoll]

Glad to hear, David --
And BTW, worth noting is that the Wingate South Park BLPH last July had
nested with what I believe was (Scott Somershoe can confirm, as it was he
who advised me via eBird review) a Black x Eastern hybrid, with two
resulting offspring. They apparently nested somewhere across the street
just east of the pond outlet.

[cobirds] Sapsucker in Denver City Park

[Patrick O'Driscoll]

Since 11:30 am high in trees lining path that leads SE from tennis courts
and horseshoe pits. Flighty and unpredictable but seems to be moving SE.
Unsure if Yellow-bellied or Red-naped but both exceedingly rare here. Will
confirm after viewing photos at home.

Re: [cobirds] Chico Basin

[Patrick O'Driscoll]

Chuck and Donna --

If I might interject here. I'm not a "member" at Chico Basin, but I've been
on the emailing list of Ranchlands (aka Box T Partners), the ranching
leaseholder at Chico Basin and the folks who run the birding program, for a
while now.
Last week, Monday, March 5, they sent word that birding is reopening to
general public visitors like us (those who are not already "members") on
March 15. Here's the message I received:

Hi Patrick,

Thank you for your patience as we have thought through our approach to
birding at the Chico. The interest this year has been unprecedented! We
will be opening to day visitors starting *March 15*. The fees will remain
the same ($15 per person), and check-in will be as it was historically.The
kiosk will be moved just outside of the main headquarters cattle guard by
March 15 and sign in and out will be in person. We will provide all the
necessary sanitation measures to do our part to continue to eliminate the
spread of Covid.

We have also decided to open our annual birding membership to 15 additional
members. This will be first come first serve. If you are interested please
email me directly.

Thanks again for your interest and support!

Esther



I assume this went to all on their emailing list, or perhaps to those
who've indicated in some way that they're birders. (I once volunteered
there several years ago for one of the cleanup days around the banding
station and other spots.)

This indicates essentially the same arrangement as pre-pandemic. The only
change is that the kiosk has been moved out of the ranch HQ yard.

[cobirds] Re: Young sapsucker in Denver City Park (Denver Co)

[Patrick O'Driscoll]

After examining my photos, it's a Yellow-bellied Sapsucker at Denver City
Park on this Sunday. (I'll post pix on eBird later today.)
Streaky bits of red coming in on the crown are mixed with the "yellow
scallops" that Cornell Birds of the World describes for a YBSA juvenile;
there is none of the dark crown cast attributed to Red-naped.
Pretty sure it's a male. Early red at chin and neck are muted, almost
washed, but no room for the white of a female.
Also, FYI, I misremembered a date in my original post:
I saw adult Yellow-bellied and Red-naped sapsuckers a week apart in City
Park in April 2017, not 2018.
Incidentally, that was the first eBird record of Red-naped in the park
(with a second sighting of the same bird reported a week later).
It was just the second Yellow-bellied sighting, so today's makes the third
on record.

[cobirds] Young sapsucker in Denver City Park (Denver Co)

[Patrick O'Driscoll]

Just saw and pursued from tree to tree a juvenile-immature sapsucker,
either Red-naped or Yellow-bellied, in the southwest corner of the park
about 100 yards northeast of the York-18th Ave intersection.

Smattering of streaky red on head of this brown-tinged bird could mean
either. Both very rare here.  I’ll look at my pix at home to get a better
read.

Bird’s attention span was short so no idea if it’ll stick in that area. But
the west side of the park has the oldest trees and is also where I saw
adults of both those species a week apart in April 2018.

Good birding,

I, too, watched a similar-sized flock of Cedar Waxwings in a neighbor's

Re: [cobirds] First Creek access?

[Patrick O'Driscoll]

Charlie, it's a longer walk back to where you want to be, but if you drive
56th Avenue east from the closed parking lot and cross Tower Road, the next
major intersection ahead (stoplight 3 blocks east) is Dunkirk Street. From
there you can drive to and park at First Creek Park, a tiny city park patch
(kids-outdoors-discovery-zone) west of Dunkirk (the street where the First
Creek-Green Valley Ranch hotspot is centered).
To get there:
Turn right onto Dunkirk From 56th and go south to 53rd (just after crossing
south over First Creek). Turn right, driving about 2-3 blocks west until
the road curves left (and becomes Elmendorf Way). The park is on your right.
Park on the street and walk north through the little park along the
sidewalk/path (or meander through the discovery zone habitat).
You'll come out into open fields and new houses on the north side of the
creek. Continue to follow the paved path left/west along heavily treed
First Creek, and a couple of city blocks ahead, you'll cross through a
tunnel underneath Tower Road (still westbound) and enter the eastern edge
of First Creek @ DEN Open Space.
The paved path takes you west through the open space, roughly 1 mile-plus,
to Buckley Road.
I don't know where the limits of the plague closure are, but the main
prairie dog town near the 56th Avenue parking lot is well south of where
your path meets Buckley Road -- which is also where you can cross west into
the Arsenal on the First Creek Trail . . . that is, assuming the closure
doesn't into the refuge as well.

Good birding,

Re: [cobirds] Rock Wrens (?) at Rocky Mtn. Arsenal

[Patrick O'Driscoll]

There have been reliable clusters of Rock Wrens @ the Arsenal in recent
weeks, including in the boulder-filled drainage ditch by the little loop
drive around the staff parking behind the north side of the visitor center
(west of the ferret building and north of the fenced garden)  . . . .
Also, all along the length of the boulder-covered slope or dam that defines
the west/northwest shoreline of Lake Ladora.
Walk the path along that stretch and they almost seem to follow or fly
ahead of you among the rocks.
(Lots of sparrows there, too, including White-crowned, Vesper, Savannah,
Lincoln's. . . .)
I've seen at least 4-5  ROWRs in both those places my last three times out
there in late September-early October.

Individuals pop up elsewhere, too, including north of the headquarters
building (the newer building just up the road north of and beyond the
visitor center), between the north edge of its parking lot and the fence to
the bison meadows beyond.

Most unexpected sighting was one perched on a sign on the southwest corner
of the intersection of 64th Avenue (the main east--west road when first
entering the Arsenal) and Havana Street (the road that runs north to Lakes
Mary/Ladora and Rattlesnake Hill).

[cobirds] Denver City Park migrants (Denver Co)

[Patrick O'Driscoll]

The 7 Wilson's Warblers were a predictable sign Sunday of fall migration,
but the FOS Western Kingbird in a tree west of the Denver Museum of Nature
+ Science was a rare, only-in-fall visitor, too.

Sunday's big surprise, however, was a bird not recorded in the park in more
than SEVENTY years:
A MacGillivray's Warbler, skulking through small junipers and fallen limbs
beneath them, just across the park road from the southeastern most tennis
court on the west side of the park.

So, who recorded City Park's last MacGillivray's on May 11, 1950?
Who else but young *Hugh Kingery*, of course . . . .

Good (migration) birding,

[cobirds] Belated report -- Long-tailed Jaeger continues @ Chatfield SP, Douglas-JeffCo

[Patrick O'Driscoll]

Rob Raker spotted the Long-tailed Jaeger at about 7:30 a.m. Wednesday when
it landed for about a minute on the marina side of the berm that connects
to the handicapped fishing platform at Chatfield SP.
Others subsequently saw it from the platform through the morning. It went
after a gull near the platform and also floated by itself mid-reservoir on
the Douglas County side.
The jaeger also took a long north-to-south-and-back again flight roughly
along the mid-reservoir boundary of Douglas and Jefferson counties. Closer
to the dam at the return end of the flight, it chased a gull for some time.

Re: [cobirds] Cattle Egret at the Arsenal again

[Patrick O'Driscoll]

I watched this handsome bird there on July 2, appearing to harass a pair of
American Avocets, one of which had been sitting in thick green growth on
the edge of the pond/playa -- as if nesting or, perhaps, guarding young?
The egret spent several minutes poking around intently in that vegetation.
The sitting avocet had fled perhaps 50 yards north up the shore. Its mate
stood closer, perhaps 10 yards from the egret, apparently alarmed and
calling at it.
I did not see the egret come up with any avocet chicks or eggs, but when I
asked other better birders later about its behavior, they said Cattle
Egrets are opportunistic foragers known for going after avian young.
I had thought of them primarily as bug-eaters until I looked up photos on
Cornell's "Birds of the World" entry for the species. Sure enough, they
show Cattle Egrets eating scorpions, geckos, toads, a Barn Swallow, even an
Anna's Hummingbird.

I think I saw this same bird several days earlier (June 29) near sunset. It
was following a small herd of the refuge's bison out of the livestock gate
at 72nd Avenue and Yosemite Street.
For anyone unfamiliar, that's the opening in the bison fence at the
northwest corner of what was once the Arsenal's short, "loop" route -- the
original "Wildlife Drive" before the miles-long route farther north and
east was opened 3 years or so ago.
You could drive up Havana past Lakes Ladora/Mary, turn west on 72nd down
the long avenue of trees with magpie nests, and then turn south again at
that livestock gate and go down now-closed Yosemite and back to the visitor
center.
Anyway, the egret perched atop one of the stout gateposts there as the
bison moved across the road to graze south of 72nd.
Then it flew, circling before heading south and, I'm guessing, back to what
appears to be its favorite pond.

Good birding!

[cobirds] The Wingate South Park (JeffCo) Black Phoebe has a FAMILY

[Patrick O'Driscoll]

For the past 15 minutes I’ve been watching either two adults and a
fledgling or an adult and two fledgling Black Phoebes (and maybe 2 adults
too) across Carr Street from the east end of the pond. I’d seen the pond
bird catching a few flies near 4 pm and the immediately flying east across
the road to a pine tree behind a cottonwood next to a red-roofed garage
directly across Carr.

There I found two perched phoebes,  one with and the other without the
white breast,  but they were obviously together (and no, it was not one of
the several Say’s Phoebes also at the park). The parent(s) would come and
go.
I’m assuming 2 young and 1-2 adults. I’ll check the photos later when I
file my list.

Good birding!

Re: [cobirds] Trespassing at Box Elder Creek

[Patrick O'Driscoll]

Thanks, Karen, for the note.
I regret that I did not see it while in the field today . . . in fact, I
started my eBird list for Box Elder Creek about 3 minutes after you posted
here.
Which is why I was still oblivious when I posted to CoBirds this afternoon
after sighting the pair of Red-headed Woodpeckers working on a cavity nest
along the creek.
I apologize to CoBirds readers for not knowing that word had already gone
out here about trespassing at Box Elder.
I was not flouting the rules, but I was careless in my ignorance of them.

I, too, was approached as I departed Box Elder Creek a little after 2 p.m.
A friendly and polite guy with USDA's APHIS "wildlife services" (he works
in the area to minimize wildlife-aircraft encounters) advised me of the
off-limits status. In fact, portions of some roads many of us have
routinely driven there -- notably Hudson Road north of 72nd Avenue -- are
supposed to be entirely off-limits. Personally, I think the airport's
"PRIVATE PROPERTY" signs are a little ambiguous (more on that below), but I
freely admit I had not read the "fine print" at the bottom.

I had birded across the east side of the airport all morning and into the
afternoon, starting at 56th and Hudson Road (aka Hudson Mile Road), working
up north of 72nd to 96th, along 96th across the creek and back, and then
north along Umpire Road (which parallels the easternmost airport security
fence at the end of the east-west runway in DIA's northeast corner) and
over to Box Elder Creek @ 104th Avenue.
Most of those roads, according to the guy from APHIS, are off-limits, as is
all the land along them, including any unmarked roads that branch off them
(usually oil-well access roads).
I suppose that technically, we can bird from the shoulder of the roads that
are still open to us, but that's all. In a way, it's a little like driving
the Wildlife Loop at Rocky Mountain Arsenal NWR, where you can't get out
and walk around, and there are a number of side roads labeled off-limits.
Unfortunately, virtually none of the side roads is labeled that way, and
the white "PRIVATE PROPERTY" signs are far-flung and
fewer-and-farther-between. I think most if not all of us missed that fine
print saying it's all private and we're not allowed to stray off the main
roads.
In most cases, that "PRIVATE PROPERTY" sign is paired with a white,
same-size "NO DUMPING" sign stacked atop it. It's hard not to assume that
together, they apply not to those unmarked side roads or to an old
two-track trail, unsigned and unfenced, along a shaded, grassy creek, Turns
out they apply to almost EVERYthing around them.

And you know what they say about "ass-u-me" . . . . I was wrong, and the
guy from APHIS set me straight.
BTW, there's one of those "PRIVATE PROPERTY/NO DUMPING" double-signs posted
on 1o4th just before you reach Box Elder Creek -- clearly visible IF you're
coming from the east (driving west on 104th from Imbogen Road).
But there's no such sign on the west side, and having come in from the
south/west, I assumed (that word again) the creek was wide open.
Alas, open no more, if it ever was.

[cobirds] Red-headed Woodpeckers nest-building @ Box Elder Creek (Denver Co)

[Patrick O'Driscoll]

Right now watching a pair of Red-headed Woodpeckers excavating a cavity in
a prominent standing dead tree (V-shaped) roughly two- thirds of the way
south from 104th where the 2-track finishes the initial big bend to the
southeast. Thee


Tree is 25 yards from the trail; cavity faces east about 25 feet up the
left part of the fork. Saw them copulate earlier on a higher branch. One is
brightly red- headed and the other a bit more rusty red.

Re: [cobirds] Re: Clarification on RBA

[Patrick O'Driscoll]

Thanks, Diana, and just for the record, the numbers on our volunteer team
had shrunk to the point that we no longer could compile in more frequent
weekly rotations and still have lives beyond the RBA.
We continue to marvel at how Joyce Takamine did this largely by herself for
more than a decade.

Monumental task? Yes.
Thankless? Not at all.
Unfortunately, we could not recruit and retain willing volunteers to help
us continue.

Thanks for understanding, and good birding to all.

The Colorado Rare Bird report is an informational service.



Because of statewide coronavirus “Safer at Home” orders, this report is
meant to keep homebound readers abreast of rare bird sightings across the
state during spring migration. *It does NOT endorse and is NOT meant to
encourage the pursuit of rare birds beyond your local area.*



We urge readers to respect state and local restrictions on non-critical
travel.

*As potentially asymptomatic outside visitors, unethical urban/suburban
“chase” birders who travel to more remote locales may risk exposing
isolated Colorado populations to the virus.*



To ensure your safety and that of others while birding, do the right thing.
Please practice physical distancing, wear face masks and follow all other
Covid-19 precautions.

*Spring migration notes*

Colorado’s remarkable 2020 warbler migration (more than 25 species
considered rare here) may be starting to wane, at least at hotspot traps
for multiple species. But some star warblers linger as birder attention
remains strong.

Other warblers, tanagers, vireos, grosbeaks and thrushes seem to be
everywhere. Shorebirds are moving through, but more quickly – from
sandpipers, dowitchers, phalaropes, Whimbrels and a Ruddy Turnstone to
godwits, yellowlegs, Glossy Ibis and other leggier waders.

Catch any flycatchers yet? The roster so far already includes Alder,
Ash-throated, Cordilleran, Dusky, Hammond’s, Gray,Great-crested, Least,
Olive-sided, Vermilion and Wood-Pewee, to name a few.

Note: In an attempt to limit an already-overlong daily report, we are
omitting these recently listed species from the daily report:

*White-eyed Vireo, Yellow-throated Vireo, Chestnut-sided Warbler, Tennessee
Warbler, Black-and-white Warbler, Nashville Warbler, Palm Warbler,
Blackpoll Warbler, Northern Parula,* and* Summer Tanager.*

Please continue, however, to report these birds and other finds on COBIRDS.

The Colorado Rare Bird report is an informational service.

Because of statewide coronavirus “Safer at Home” orders,* this report is
meant to keep homebound readers abreast of rare bird sightings across the
state during spring migration. It does NOT endorse or encourage travel to
see or "chase" rare birds beyond your local area.*

We urge readers to respect state and local restrictions on non-critical
travel and limits on outdoor activities that include birding.

To ensure the safety of yourself and others while birding, please practice
physical distancing, wear face masks and follow all other Covid-19
precautions.

*Spring migration notes: *

Either this has been an exceptional migration, or “stay local” has its
benefits, as recent sightings attest. Certain birds we would all be proud
to find or see seem to be everywhere. In an attempt to limit an
already-overlong daily report, these recently listed species are being
removed:

*White-eyed Vireo, Yellow-throated Vireo, Chestnut-sided Warbler, Tennessee
Warbler, Black-and-white Warbler, Nashville Warbler, Palm Warbler,
Blackpoll Warbler, Northern Parula, and Summer Tanager.*

Please continue, however, to report these birds on COBIRDS.

Robert did the same thing with his dad at the first stakeout at Bobcat

It was my first encounter with them, and now I can say that I went birding
once with Bob Spencer.

[cobirds] Mockingbird, towhees and more in Denver City Park

[Patrick O'Driscoll]

It was a mem0rable Thursday morning for spring migrants in Denver City Park:

+  First record of a Northern Mockingbird in *72 years*.
According to eBird, the species was last seen in the park by young *Hugh
Kingery* on May 15, 1948, the third oldest eBird record until now for any
of the 174 species seen in the the park since the 1940s.
This one briefly paused on the park road west of Duck Lake, tail pointing
skyward, then flew to a small tree before disappearing over the fence into
the Denver Zoo
+  Two Green-tailed Towhees, another seldom-seen visitor, one of them
hanging with two White-crowned Sparrows along that same zoo fenceline
+  Spotted Towhee, an infrequent visitor
+  Three Vesper Sparrows
+  A pair of Swainson's Hawks, perched in trees at the north and south ends
of the big lawn south of the Denver Museum of Nature + Science

On a personal note, I also saw my first Great Horned Owl in nearly 200
visits to City Park. It was in a spruce tree near the 21st Avenue gate,
being mobbed by Black-billed Magpies and Blue Jays, with robins, flickers,
finches and doves watching the action.
Finally, the park's first Double-crested Cormorant chicks of 2020 (9 in 3
nests) have hatched and are begging to be fed at the Duck Lake rookery,
with more than 550 adults and 260 nests.

Good birding!

Re: [cobirds] Re: Migration Weather Advisory: Tuesday All Day

[Patrick O'Driscoll]

I agree with Rob, Bryan.
Anecdotally, I kept an eye on a couple of my patches on Tuesday, given your
"migrational turnover" weather forecast.
Wouldn't you know it -- I had a yardbird first of 7 Chipping Sparrows at
home off Colfax in very urban east-central Denver, and a FOS Ruby-crowned
Kinglet and an unexpected Osprey soaring overhead, both in Denver City Park
about a mile from home.
Thanks again for your interesting and informative posts.

The Colorado Rare Bird report is an informational service.

Because of statewide coronavirus “Stay at Home” orders,* the purpose of
this report is to keep homebound readers abreast of rare bird sightings
across the state during spring migration.*

*It does NOT endorse or encourage illegal travel to see or "chase" rare
birds beyond your own local area.*

We urge readers to respect state and local restrictions on non-critical
travel and limits on outdoor activities that include birding.

Please bird ONLY at or close to home and ONLY with universally promoted
safety precautions, including physical “social distancing” and face
coverings.

Or, as Dave Leatherman noted this week, “Be like a Cedar Waxwing . . . very
compliant in their wearing of masks.”





Birders have been helpful by reporting updates to COBirds. Thanks!

CAPITAL LETTERS denote very rare species, as listed by the Colorado Bird
Records Committee at the CFO website.

(*) indicates new information on a species.

For more information on birds seen today, go to cobirds.org and scroll to
the bottom for “Recent eBird Sightings.”

*Spring migration notes: *

Swallows, vultures, Broad-tailed Hummingbirds and a few Swainson’s Hawks
and Sage Thrashers have begun to return. Burrowing Owls, too. The sparrow
and longspur migration is also upon us. The curtain is rising on shorebird
migration, too.

[cobirds] Late-migrating Sandhill Cranes, Denver County

[Patrick O'Driscoll]

Apologies for this late posting after eBird flagged my Thursday sighting
(just filed this afternoon) of 66 Sandhill Cranes circling at midday Nov.
14, high above Denver City Park and the edge of downtown. I heard the
telltale rattle/bugle overhead of a few in the flock shortly before 1 p.m.
After circling for a couple of minutes, the birds regrouped and continued
south.

[cobirds] Gray Catbird, Denver County

[Patrick O'Driscoll]

I have a late-to-leave Gray Catbird in my yard in east-central Denver, just
off East Colfax about 4 miles from downtown. Definitely a new yard bird,
and a surprise to see around here, even in an unseasonable snowstorm.
I didn't recognize it at first, puffed against the snow and wind. It was
hunkered down with an American Robin and a couple of Euro Starlings in the
blackthorn tree out my kitchen window on the side of the house.
It appeared to be eating some of the blackthorn berries (I've read these
are considered bird food of last resort?). So were the robin and starlings.
The catbird has since flown back and forth to to lilac bushes in the
backyard, where juncos, jays, chickadees and house finches are in abundance
at the feeders this snowy day.

[cobirds] Sandhill Cranes flying southeast over east-central Denver (Denver County)

[Patrick O'Driscoll]

A few minutes before noon, a flight of about 65 Sandhill Cranes flew
overhead, 4 miles east of the State Capitol and just off East Colfax,
heading southeast.

[cobirds] DFO Sunday 10/27 field trip to First Creek (Denver, Adams counties) -- CANCELED

[Patrick O'Driscoll]

To no surprise, driving conditions will be dicey before the 7:30 a.m. start
and walking/birding will be tough in wind, ice and snow.
So this officially cancels the planned Denver Field Ornithologists field
trip to First Creek @ DEN Open Space and First Creek Trail-Rocky Mtn
Arsenal NWF.
Thanks.

Re: [cobirds] Re: Ani still here

[Patrick O'Driscoll]

I agree with Rachel. Purely anecdotally and FWIW, I see the species every
January when spending a week or two in Puerto Vallarta.
The birds around Isla Cuale, the stream that flows through the heart of
town, don't exactly beg for handouts.
But they do freely wander the island and its thickets within a few feet of
the stalls of vendors selling tourist items and food.
And yes, the ones I encounter are approachable. They are also rather
s-l-o-w and unhurried.

Re: [cobirds] Potential loss of Chico Ranch for birding (Pueblo and El Paso counties)

[Patrick O'Driscoll]

Thanks for the heads-up.
I'll be curious to know just how someone could "inadvertently add" nearly
2,000 acres of Chico Basin Ranch to Stewardship Trust back in 1998.
Count me skeptical of this . . . what, exactly -- excuse? Justification?
