Hi Scott.

There is a Common Loon, breeding plumage at Union Res. east of Longmont. He was
50 feet off shore, on the south side, where there are signs saying NO FISHING.

[cobirds] John James Audubon exhibition coming to Longmont Museum.

2011-06-03 Thread Scott E. Severs
Hi birders,

This looks like it might be good with many additional events to take part
in. June 4 - September 18, 2011

http://www.ci.longmont.co.us/museum/exhibits/audubon.html

From the website: The Longmont Museum is very proud to present an exhibition
of 64 prints from Audubon’s first edition, plus four large animal prints
from his later Imperial Quadrupeds edition and prints from later editions
and several of Audubon’s contemporaries. This exhibition also features
several original oil paintings by Audubon, as well as personal belongings
such as the silver cup presented to his engraver upon completion of the
publication of volume two of “The Birds of America.”

Enjoy,

Coolest Bird, the Black Swift, Reveals Its Migratory Secrets
   Posted by: Stephen Jones curle...@comcast.net
   Date: Sun Oct 23, 2011 2:02 pm ((PDT))

The Coolest Bird, The Black Swift, Reveals Its Migratory Secrets.

Jason Beason, Rocky Mountain Bird Observatory

Tuesday, October 25, 7:15 p.m., Boulder Unitarian Universalist Church, 5001
Pennsylvania Ave.

Black swifts nest behind waterfalls in remote mountain canyons. Until
recently, we knew very little about their migratory and wintering habits. In
2009 researchers from Rocky Mountain Bird Observatory paired with the US
Forest Service to track four radio transmitter-equipped swifts from nesting
areas in Colorado to wintering areas in South America. The data from the
devices indicate that three of the four swifts spent the winter of 2010 in a
country south of the equator that currently has no sighting records for this
species.

Jason will tell us how the researchers pulled off this amazing feat and also
explore the unique nesting ecology of these fabulous birds. Conversation and
general hobnobbing begins at 6:45. This Boulder County Audubon monthly
program is free and open to all.

[cobirds] re: Snowy Owls

2011-12-31 Thread Scott E. Severs
An important note from ebird.org:

An important word of caution about this striking and photogenic
species--the birds we see in the states are already stressed, since
they moved from locations in the north due to a lack of food. One of
the southeast Wisconsin Snowy Owls in Ozaukee County was seen for a
few days and then found dead by a farmer. Apparently the bird was
extremely emaciated, so it likely starved to death. While very
beautiful and often approachable, life for them can at times be very
difficult, and keeping a good distance so as not to disturb them is
the best approach. Please don't use live mice to lure them in to
roadsides for photography. Flushing a large raptor, especially a white
one can catch the attention of nearby crows causing unnecessary
mobbing. We want these birds to successfully over-winter and then
return back to the tundra to breed next spring.

I agree - better that these owls survive than collect digital dust
on someone's hard drive or photo site. As this species roosts during
the day for the most part if you flush them, you are causing energetic
stresses on the bird. If they flush, you need a better camera/scope,
or a blind.

[cobirds] amazing US invasion, it continues to SNOW

2012-01-04 Thread Scott E. Severs
Hi Birders,

A brief look at reports from neighboring states shows 89 +/- Snowy
Owls observations in Nebraska, and 30 or so in Kansas. Wow! Likely the
largest irruption of the species in nearly 40 to 50 years.

Take a look as various state listserves at:
http://birdingonthe.net/birdmail.html

Kansas KOS map: http://ksbirds.org/KS_SNOW_11_12.htm

I hope folks will report their Snowy Owl (and other bird) sightings to
ebird.org as it will provide a historical snapshot of sightings that
can be used in real time by researchers. As said before ebird is
really fun and EASY to use and your sightings become an easily
accessed diary of your birding life. And your sightings contribute
almost instantly to the knowledge of bird distribution in the world. I
am surprised more people don't use it but then I admit am not the best
when it comes to CRBC reports (working harder on that New Years
resolution).

If you need help with ebird, drop me a line, or there are many others
available to help.

University of Colorado's Rebecca Safran and Martin Vitiousek will share
their fascinating research on the role of sexual selection in shaping
behavior and appearance of barn swallows. What makes males attractive to
females? And why are some traits (such as long tails) favored by some female
populations while other traits (such as bright colors) are favored by
others? How have these preferences shaped barn swallow evolution and
divergence?

[cobirds] RMBO Dinosaur Ridge Hawk Watch opens March 1.

2012-02-26 Thread Scott E. Severs
The Dinosaur Ridge Hawkwatch supported by the Rocky Mountain Bird
Observatory begins its season March 1 and runs officially through May 7. It
is entirely staffed by a volunteer crew of counters and observers under the
leadership of RMBO staff biologist Jeff Birek.

Visitors are welcome to come by and help watch for migrating raptors. The
hawkwatch is located along the top of the Dakota Hogback along the trail
leading south approximately 0.55 miles south of the Stegosaurus Parking Lot
located at the southeast corner of County Rd 93 (aka Colorado 26) and I-70
(exit 259). Hours are generally 8am to 5pm daily.

Here are some links on the site:

http://coloradocountybirding.com/county/bird_a_county.php?name=Jefferson#563

http://www.rmbo.org/v3/OurWork/Science/CitizenScience/HawkWatch.aspx

https://www.hawkcount.org/siteinfo.php?rsite=123

Other notable birds are local Peregrine and Prairie Falcons, Bushtits,
White-throated Swifts, Rock Wrens, Mountain and Western Bluebirds, plus
many other migrating birds pass by the site. Unlike most bird counts,
hawkwatching involves observing from a single point and counting migrant
raptors as they pass by on their way north.

Good Hawk Watching!

 I was driving through central Boulder today and saw two birds that were

couldn't really see their wings- but most of their body except their tails
looked like a light grey-brown.

This description seems good for Mississippi Kites. Location Valmont and

[cobirds] Dickcissel irruption article and atlas blocks

Hi birders,

An article summarizing the current Dickcissel irruption can be found here:

http://ebird.org/content/ebird/news/dickcissel2012

I have observed several singing males in our atlas block Hygiene SE
but am trying to find some birds that have avoided multiple hay cuts
for a successful nest. So if you have atlas blocks in appropriate
habitat in our western plains/foothills interface, it might be worth
revisiting your block to see if you have breeding Dickcissels. I have
my eye on a nice weedy patch with lots of annual sunflower.

[cobirds] Broad-winged Hawk redux Longmont 9/23

2012-09-23 Thread Scott E. Severs
Hawkers,

After deciding not to go to my favorite hawk watch west of Boulder, I
decided to see who would float over near my home in SW Longmont today. I
ended up seeing a departure (over a 2.5 hr period) of 16 Broad-winged Hawks
from Longmont, most less than 200m off the ground. It appeared that many,
based on their height of flight roosted overnight in the older parts of
Longmont (possibly near a traditional vulture roost), or along the St.
Vrain Greenway. My observations were in this order: 1, 4, 1, 6, 3, and 1.
Departure was somewhat late, with the largest mini-kettle seen around 1230
hrs. I started around 1100 and finished at 1330 hrs. Birds moved mostly NE
to SW, often following a path that the vultures regularly use in SW
Longmont.

Broad-winged Hawks are peaking at our latitude at this time, and will
decline quickly now into generally the first week of October. Preferring to
roost in trees, our heavily timbered Front Range towns provide stop-over
sites for this species. I believe this species migrates more commonly than
expected here but is under-reported. Dave Leatherman's post today of the
kettle near Ft. Collins re-enforces this point.

Additional birds included 3 Northern Harriers, 3 Swainson's Hawks (not
displaying migratory behavior), and an adult Cooper's Hawk that seem be a
local showing curiosity in the group of 6 Broadies in the nearby airspace.

What worked for me today was a clear view to the north, positioned south of
the heavily treed portions of town. And credit is due to the Turkey

[cobirds] Palm Warblers, Union Res. (in fee area) Weld County 9/25

2012-09-25 Thread Scott E. Severs
While working at Union Res. today I saw one Palm Warbler and heard another
in the trees between the entrance station and the south end of the
reservoir among droves of Yellow-rumped Warblers of both ssp. As Steve
Mlodinow pointed out the water bird variety is good right now and could be
worth checking frequently for new arrivals.

The entrance ($8.00/car) is accessed off Weld County Road 26 east of the
County Line Road. Of course most of the water birds can be seen outside of
the fee area from the county roads, especially 28.

[cobirds] Golden-crowned Sparrow, Teller Farms, Boulder, Cnty 10/9

2012-10-09 Thread Scott E. Severs
For the third fall-winter in a row, a Golden-crowned Sparrow is frequenting
the windbreak of planted junipers at the N. Teller Farms parking lot
(Valmont Rd, just west of 95th St). The bird is in adult non-breeding
plumage. As the general date for the arrival of this species at our
latitude is around the first half of October, after work I went to see if
this individual might have arrived. Alas I observed it today around 6pm
with a juv. White-crowned Sparrow. Amazing fidelity to this winter spot if
it's the same bird, seemingly to coincidental not to be.

Good birding!,

[cobirds] Dr. Weber talk, Boulder, 1/10/2013

2012-12-29 Thread Scott E. Severs
BCNA Winter Program
Bird Count Retrospective
with Dr. William Weber

Though best known as the dean of Colorado botanists and founder of the
University of Colorado herbarium, Bill Weber has been a birder and
naturalist all his life, beginning in the 1930s when he founded the
Sialis Bird Club in Bronx Park. He and his young friends were actually
responsible for the Wooden Dovekie incident of the Christmas Census.
His notebooks from those early years have contributed to a new book by
Paul Buckley on early birding in the New York City area.

Dr. Weber, now 94, will share stories from those early years. In the
spirit of the occasion, we will also discuss results of the 2012
Boulder Christmas Bird Count, conducted on December 16. Copies of Dr.
Weber's seminal field guide, Colorado Flora, Eastern Slope, will be
available for purchase and signing.
Join us on Thursday, January 10, 7 p.m. George Reynolds Branch
Library, Table Mesa Drive opposite King Soopers.

[cobirds] Fwd: volunteer bird research opportunity RMNP

2013-03-14 Thread Scott E. Severs
The following was reported on the volunteer.gov website.

Enjoy,

Scott Severs
Longmont
_

Opportunity Description:

NOTE: This volunteer position is available only for those within the
commuting distance of Estes Park, Colorado (there is no volunteer
housing or camping for this position).

Colorado State University researcher is seeking assistance for bird
research in Rocky Mountain National Park. The study takes place within
stream-side willow habitat on the east side of the park. The purpose
of the study is to determine if willow height, vegetation cover, or
the presence of elk exclosure fencing affects the quantity or species
of birds using the habitat. This will be the second year of a two-year
study.

Position description:

Volunteers will perform point counts during the dawn chorus at study
sites from May 1 through the first week of July. Point counts will
take place from approximately 5 a.m. - 10 a.m., seven days per week.
Study sites may involve hiking up to 0.5 miles over uneven, swampy
terrain. Volunteers should be comfortable with identifying riparian
bird species and meadow bird species of Rocky Mountain National Park
by sight and sound. Volunteers will receive a species list in advance.
Volunteers may participate for one day or multiple days. Volunteers
who attend the free training may be eligible to perform counts
independently. Volunteers unable to attend the training are still
encouraged to participate; however, you will be accompanied by a
trained field technician. A free, voluntary training will be scheduled
on or around May 1, 2013; specific date, time, and location to be
determined.

Start date: May 1, 2013 (flexible)

End date: July 5, 2013 (flexible)

During survey work this AM I was struck by the state of slow leaf out in
the cottonwoods. It made for amazing observing conditions for arriving
migrants, and it seems many species will arrive before well ahead of the
majority of leaf out, making for great but odd observing conditions. I was
especially struck by seeing Warbling Vireos and Orchard Orioles on bare

[cobirds] fwd: Twin Lakes migrant trap under threat (Boulder Co.)

Many of you have seen excellent birds at Twin Lakes in Gunbarrel. Last night a

 Subject: [nature-net] Need advice on what to do about the Twin Lakes tree 
 removal
 
 Hi. 
 
 Some of you may remember me. I was very active for a few years in the early 
 2000s (and used to do the newsletter and website). 
 
 I have lived in Gunbarrel since 2001, and just on the east side of the lakes 
 since 2008. I just learned, and confirmed with the county, that the North 
 Boulder Farmers ditch company was told by the State Engineers to remove all 
 of the trees that surround the Twin Lakes, including those on the outside of 
 the trails too. The county has not seen the report, but were told it was due 
 to seepage, drought and that if a tree were to ever fall into the water, 
 there would be dam issues. I asked why this was happening now - what changed. 
 I was told that the inspector who had this area for years finally retired, 
 and this was a new inspector. Tree removal is supposed to start happening 
 now. So far, I can tell they have been trimming. 
 
 This is awful on so many levels. The wildlife is going to be hurt 
 tremendously. There hasn't been anything in the papers yet either. I, and my 
 neighbors, have been trying to spread the message by word of mouth initially 
 while we look for info. We want to fight this since it is ridiculous. And I 
 am sure if more people knew, they would also be outraged.
 
 So, any help/advice is most appreciated. 
 
 Thanks,
 Susan Winter

[cobirds] Fwd: Twin Lakes tree removal update (Boulder Co.)

Folks,

Below is an update regarding the possible tree removal operation at the Twin 
Lakes birding hotspot. Thanks to Maeve Conran at KGNU, Elena Klaver, Susan 
Winter, and several local birders who did some sleuthing into the issue. Looks 
like some continued discussions will be needed with the agencies in charge, but 
for now the cutting has been delayed until public meetings are held.

 Subject: Re: Twin Lakes tree removal
 
 Hi everyone
 I've spoken with Ryan in the Division of Dam Safety at the State Engineers 
 office who confirmed that due to public outcry over the tree removal, no more 
 trees will be removed until a public meeting is held (that is yet to be 
 scheduled and may not happen until late this year or early next year). I also 
 confirmed this with John the President of the Boulder and Left Hand Ditch 
 Company. The Division of Dam Safety also said that they had required that 
 smaller newer growth trees be cleared out, and that no directive to remove 
 any of the larger trees had been given at this time. 
 I think it would be interesting to talk to someone about the importance of 
 that area to migrating birds...and also how all these different interests 
 play out together (State engineer's office who say they need to mandate this 
 type of thing for safety purposes, ditch company - who's responsibility it is 
 to get irrigation water to their customers - local residents who enjoy the 
 trees - Boulder parks and open space who want to keep area for rec.). 
 Thanks
 Maeve

Bald Eagles Are Back In A Big Way — And The Talons Are Out
by Elizabeth Shogren

NPR - September 4, 2013

Decimated by hunters, insecticides and other human pressures in the 1960s and 
1970s, America's emblematic bird is once again flying high. Roughly 10,000 
mated pairs now nest in the continental U.S., up from about 500 in the 1970s. 
But more birds also means fierce competition for territory and mates.

[cobirds] Bird Trax for Boulder County using eBird

2013-11-10 Thread Scott E. Severs
For fun I created a Bird Trax application on Google sites for Boulder
County. It documents recent (2 weeks) sightings, rarities, and checklists
on three tabs using eBird data.

You can check it out here:

https://sites.google.com/site/scottesevers/

To create your own Bird Trax visit this page at ebird:

[cobirds] teen birding camp scholarship - Summer 2014

2013-12-16 Thread Scott E. Severs
Steve Jones (CFO's 2013 Ron Ryder Award Recipient) is looking for
interested teen applicants for a paid ornithological study adventure to Hog
Island Maine.

Boulder County Audubon Society offers a full scholarship to a summer
ornithology camp for Colorado students ages 15-17. The Audubon Camp
includes field identification, bird song recognition, conservation
practices, and participation in Audubon's seabird conservation field
research.

Steve says that although preference would be given to students in Boulder
County Audubon's service area, the scholarship is open to all Colorado
teens. So far no one has applied and the deadline in January 15, 2014. Do
you know a deserving teen birder in Colorado?

Full details and applications can be found here:

[cobirds] Boulder County Audubon meeting: A Big Year with Sandy Komito 1/28 7:30pm

2014-01-25 Thread Scott E. Severs
Tuesday, January 28, 7:15 p.m.

Boulder Unitarian Universalist Church, 5001 Pennsylvania Avenue, Boulder

In 1998 Sandy Komito set the record for the most birds ever seen by one
observer in North America in a single year: 748 species. His feat was
described in The Big Year book and movie. During his 1998 big year, Sandy
spent 270 days in the field and logged 275,000 miles. He also completed a
record-setting big year in 1987 (722 species). He is currently striving to
photograph at least 700 species of North American birds, a number he has
already exceeded. Sandy will talk about his adventures, show photos of some
of the rarer birds he has encountered, and set the record straight about
what really happened during that imaginatively-portrayed 1998 big year.

Free and open to all.

[cobirds] fallout conditions today

2014-05-11 Thread Scott E. Severs
Although I'm stuck at home getting ready to leave for a long work
trip, in my brief walk with the dog just now the trees were active
with birds (thrush sp. Spizella sp. Western Kingbird, Yellow Warbler)
in about a tenth of a mile. So pull on the galoshes and the rain gear
and go check out migration today and tomorrow! Riparian areas and the
mouths of foothills canyons could be very interesting.

What are you seeing?

The Ghost with Trembling Wings, with Scott Weidensaul

University of Colorado Ramaley Auditorium, Sunday, August 24, 2 p.m.

Presented by Boulder County Nature Association



Don't miss this rare opportunity to hear world-renowned nature writer and
migratory bird researcher Scott Weidensaul talk about the quest to find
reportedly extinct or nearly extinct species around the globe, including
the Ivory-billed Woodpecker and Bachman's Warbler. Scott is an extremely
engaging speaker, and his talks are full of stories and anecdotes that
reveal all that is wondrous in the natural world. Scott's first major book,*
Living on the Wind,* was a semi-finalist for the Pulitzer Prize.



*At the core of Weidensaul's book are fundamental questions about who we
are, the state of our planet, and the faltering health of our ecosystems...
*The Ghost with Trembling Wings is as much about people as the animals they
search for.

[cobirds] Colorado Gap Analysis and Baird's Sparrow

2014-09-08 Thread Scott E. Severs
Birders,

In addition to the Colorado's terrific Breeding Bird Atlas and eBird,
another good source for predicting potential breeding habitats for Colorado
birds is the Colorado Gap Analysis Land Cover Maps, created by an analysis
of Landsat imagery.

While the Gap analysis vertebrate maps are a little too broadly modeled to
be useful for breeding birds, the predicted land cover vegetation maps are
quite useful, especially the Graminoids (grasses) and Forbs (non-woody
plants). This shows up nicely for tall and mid-grass prairies in Elbert and
El Paso Counties, matching up nicely with the uplift and resulting higher
moisture levels of the Palmer Divide (the natural boundary between the
Platte and Arkansas River drainages).

Along with a fair amount of ranches in Conservation Reserve Program (CRP)
enrollment, these counties have habitat suitable for mid- and tall-grass
bird species. In 2008, a small population of Chestnut-collared Longspurs
were discovered breeding in mid-grass prairie east of Calhan Highway along
Judge Orr Road in El Paso. A Baird's Sparrow was also observed here singing
in planted CRP grasses, but was considered migratory as additional visits
failed to turn up this individual after it was first observed in mid-May.

The continued rainfall pattern will make these areas worth searching next
spring. Elbert County will be a good destination too. Finding breeding
Baird's Sparrows would be a long shot, but a worthy coup. :)

[cobirds] ebird portals

2014-10-07 Thread Scott E. Severs
Hi All,

Not to beat a dead horse, but regional portals come more from a
research-based approach (rather than a purely birding approach, although
that is an important component). Within portals local ornithologists and
experts provide site specific information, present regional projects, or
encourage proper ebird and research documentation of special status birds
being monitored by local agencies or NGOs within the portal's area of
interest.

Another example portal provides a gathering place for the next generation
of birders and ornithologists, the Young Birders Network.

CFO's county site is a fantastic resource. But it shouldn't be confused for
an ebird portal where local conservation or species specific research can
be implemented and fostered by scientists looking to generate regional
data.

Cobirds has never been a very good conservation venue. It's an excellent
RBA and current sightings listserve. Will Colorado or a subset of the state
ever have a portal? Unknown, unless Cornell and a local partner (say RMBO)
identify the need or interest for one.

Alas the amazing variety of ways of participating in birding would be
enhanced, not diminished by a regional or state ebird portal.

Happy Fall!

A Red-necked Grebe was doing a Nessie impression in the fog at Lagerman
Reservoir this morning. The fog and light hampered observations toward the
middle but a good variety of regulars was present.

Post your reports to eBird and Cobirds as folks get out to see things.


Good Birding,

It should be noted that House Finch, Cassin's Finch, and Purple Finch were
placed in the new world genus Haemorhous in the 2012 AOU supplement.

 Bryan's finch looks good for a Purple to my eyes. Nice find!

[cobirds] possible Bohemian waxwings, Boulder 1/5

2015-01-05 Thread Scott E. Severs
Hi Birders,

During a staff meeting, I caught a glimpse of a flyover of 16 or so
starling-sized waxwings moving south outside my office (49th  Pearl). GISS
as well as time of year strongly suggested they were Bohemian Waxwings.

Happy New Year!
