Re: [cobirds] Why the Cassin's Finch invasion?

I had about 30 in SW Longmont, and loved every minute of it! Plus a few 
Pine Siskins.

Here's a little video I shot: https://youtu.be/FvhPuFv4EM8

[cobirds] ALL WHITE RED-TAILED HAWK (4/4/2020) Westminster City Park

[Scott Severs]

Great sighting! As said by others this bird has been there for many years. 
Including one round in the rehab center at the birds of prey foundation after 
being hit by a golf ball resulting in a broken wing. It’s quite the survivor 
with the amount of urbanization that has gone on between Boulder and Denver.

Thanks to Nick Komar for his thoughtful reply to my query. His CFO trip was 
carefully coordinated to lessen impacts to ground-nesting species. If you

[cobirds] Re: Fort Collins Turkey Vulture roost (Larimer)

[Scott Severs]

Similar tree removal has occurred at the traditional roosts in Boulder and 
Longmont. The vultures were quite adaptable - moving to other trees in the 
area of the original roost, or a block or two away. Continuous use of the 
spruce trees by the birds gives the trees a characteristic bare branch look 
where the needles have all been worn away. As for the vulture effigy, it's 
just a matter of time before spring winds send it to Kansas :). In most 
cases very few of these deterrents have any lasting power as the birds 
adapt and recognize that they pose no threat, e.g. fake owls, and raptor 
playbacks.

Red Rocks free-roaming cats are prohibited - but alas so is bird feeding :( 

But I thought I remember that there was an exception for the Trading Post.

I would call Denver Parks as that is who manages RR.

 I try to chase it off but it doesn't take long before it returns.  If the

 to the 4-year run of this Golden-crown. Any ideas on what we can do?

[cobirds] Re: Comments on reported Boulder Ross's Goose, Bay-breasted Warbler and update on Larimer LBBGs

[Scott Severs]

Thanks to Nick getting some photo documentation shots of the Ross's-type 
goose at Dodd Reservoir, I believe there are two in Boulder County. The one 
I observed yesterday at Fairgrounds Lake (at essentially the same time as 
Nick was over at Dodd) was a very white individual appearing adult-like 
until I scoped it, with limited dusky feathers on head and nearly all white 
on back. It had a darkish line from bill to eye and a small triangular 
bill. Bird smaller than nearby Cackling Geese, I lean toward a pure Ross's 
for this bird.

There is definitely something to this aphid thing as all the late warblers 
in Boulder over the years seem to have an affinity to planted pines in 
office parks! I have a ton of trees to sort through on my lunch breaks! :)

 I have posted some photos of the Larimer County Brant, the Boulder County 
 Bay-breasted Warbler and the three Chen geese reported from Longmont, which 
 includes the reported juvenile Ross's Goose, the adult white Snow Goose and 
 the adult blue Snow Goose. These are in my recent bird pix gallery at 
 www.pbase.com/quetzal.

 Update: I have heard that the 6 Lesser Black-backed Gulls are still 
 loafing in the northwest corner of Horseshoe Lake in northeast Loveland.

 Comment on Ross's Goose: The photo is not the best, but the bill shape and 
 head shape do not look right for Ross's Goose. I suspect hybrid Ross's x 
 Snow Goose. Note the lack of a vertical edge to the base of the bill.

 Comment on the Bay-breasted Warbler: First, thanks to Alan Contreras for 
 finding it, identifying it and sharing with the birding community. This 
 bird has provided a rare Colorado learning opportunity for solving one of 
 the greatest ID challenges (young Pine vs. Bay-breasted vs. Blackpoll 
 Warblers in fall) as well as for understanding warbler foraging behavior. I 
 have posted some comments on the ID features with my photos. I am thinking 
 that this is a first fall male. Anyone disagree?

 Suggestion: Everyone walk outside, find a pine tree with moths and bees 
 flying around it on this warm afternoon (indicating an aphid infestation), 
 and then check the infested pine carefully for a happy warbler. I'll bet 
 there are others out there.

Candace was one of the nicest people I have ever known. A genuinely good

[cobirds] conservation funding for birds set to be gutted by senate

[Scott Severs]

Hi Birders,

Hopefully each of you will take a moment to send a note to our
Colorado Senators as a key vote for conservation funding that benefits
the very birds you find important seeing is coming up soon. Here is a
link to get some work done for the benefit of the diversity of North
American birds:

http://org2.democracyinaction.org/dia/track.jsp?v=2c=waRJxZvfTySPeU0WE1PEP%2FEh9c97RKG6

It only takes a moment (it's even easier than submitting bird data to
online databases!) and it might increase your chances of improving
your life list or however birds enrich your life.

Thank you,

[cobirds] RMBO Dinosaur Ridge Hawk Watch, Sat. 3-6-2011

[Scott Severs]

Saturday was slow in terms of raptor migrants at Dinosaur Ridge, only two
birds observed that we could call migrants, one a very nice Prairie Falcon
that passed by at eye level. We did get to see lots of local Red-tailed
Hawks, Golden Eagles (undulating display flight high above the ridge), and a
Northern Goshawk soaring between the ridge and Red Rocks.

A nice group of nine male Mountain Bluebirds settled for a few moments on
the ridge south of the watch, some Bushtits wandered by, and Western
Scrub-Jays appeared throughout the day.

The 2011 season summary to date can be seen here:

Hi Dennis,

Yes unusual species in the GBBC database are reviewed when submitted
to ensure the accuracy of the data. Like ebird, notable sightings are
flagged for review before added to the data base thus it will not
appear immediately, but will soon, see the FAQ at birdcount.org.

[cobirds] Great Backyard Bird Count, Feb. 18-21

[Scott Severs]

Hopefully birders can spend a few minutes counting birds for the Great
Backyard Bird Count which starts tomorrow! All skill levels and ages
welcome! If you are an ebirder, you can submit records in both places.
Have fun and represent Colorado proudly. Below a summary from Cornell
on how the data is used and how to participate.

Great Backyard Bird Count Feb. 18-21, 2011

How is the information from the GBBC used?
Bird populations are constantly changing. No single scientist or team
of scientists could hope to keep track of the complicated patterns of
movement of so many species over an entire continent. The information
from GBBC participants even more valuable as scientists  try to learn
how birds are affected by environmental changes.The information you
send in can provide the first sign that individual species may be
increasing or declining from year to year. It shows how a species’
range expands or shrinks over time. A big change, noted consistently
over a period of years, is an indication that something is happening
in the environment that is affecting the birds and that should be
followed up on. GBBC information also allows us to look at what kinds
of birds inhabit different areas, such as cities versus suburban. All
the information from the GBBC and other surveys goes into a massive
bird database called the Avian Knowledge Network. AKN now holds 36
million records of bird observations which are used by scientists
around the world.

Why is the count in February?
It gives us a snapshot of how birds are surviving the winter and where
they are located just before spring migrations begin in March.
Scientists at the Cornell Lab of Ornithology, the National Audubon
Society, and elsewhere can combine this information with data from
surveys conducted at different times of the year.


How to COUNT THE BIRDS:
1. Count birds at any location for at LEAST 15 minutes—or more if you
wish. Later you’ll be asked to record the amount of time you spent
watching.

2. Write down only the highest number of each species you see together
at any one time to avoid counting the same birds more than once. For
example, if you see 8 juncos as you start your count period, then
later you see 12, and later still you see 3, you’ll only report
12--the highest number you saw together at once. Please do not add the
numbers together.

3. You’ll submit your data on a new checklist for each day you
participate in the count. It’s OK if you count at the same location
each day—submit a new list for each day.

4. You’ll submit a new checklist for each new location. You can submit
more than one checklist on a given day if you count at more than one
site.

ENTER YOUR CHECKLIST(S):
When you’re ready to enter your checklist(s), go to the GBBC website
at www.BirdCount.org and click on the big “Submit your checklists”
button at the top. You won’t see this button until 7:00 AM the Friday
the GBBC begins. Everything you need to know will be clear on the web
page as you enter your information.

[cobirds] Boulder County: Golden-crowned Sparrow 2/16, etc.

[Scott Severs]

The Golden-crowned Sparrow continues at the Teller Farms North parking lot
(95th and Valmont). Today (along with a couple dozen White-crowned Sparrows)
it was along the trail leading west from the parking area, along the fence
line with planted skunk brush and plum, with bunches of tumble mustard piled
up among the shrubs.

A Winter Wren, Swamp Sparrow, and a male Merlin (ssp. columbarius)  were
present at Golden Ponds (Longmont) on Feb. 11. The songbirds were in the
cattail marsh below the spillway that drains into the St. Vrain.

[cobirds] Re: spotting scopes and air travel - results and thank you!

[Scott Severs]

Thank you Everyone! Wow, birders are great. I share the results as several
of you asked.

The consensus is to pack the tripod in the checked luggage and bring the
optical equipment packed in the carry-on. Alas, there is the chance that the
tripod could get lost/broken with checked baggage, so it might be worth
putting in carry-on if there is room and if it collapses small enough. A few
hassles reported just trying to carry-on tripod in hand.

Another good idea passed along was bring a lock for the carry-on luggage
with a TSA approved luggage lock JUST IN CASE they ask you to check your bag
full of your optics (I think some of you would faint).

No recent changes, or restrictions reported.

Thanks again!

Enjoy,

Scott Severs, Longmont



*February 8, 2011*—The 14th annual Great Backyard Bird Count is coming
up* February
18–21*, 2011. People of all ages and skill levels are needed to count birds
in their yards, neighborhoods, or other locations across the United States
and Canada. Simply tally birds for at least 15 minutes on any day of the
count, then go 
towww.birdcount.orghttp://www.allaboutbirds.org/NetCommunity/page.redir?target=http%3a%2f%2fwww.birdcount.orgsrcid=32265srctid=1erid=5826788
and
enter the highest number of each species seen at any one time.


Coordinated by the Cornell Lab of Ornithology, Audubon, and Bird Studies
Canada, the count provides an instantaneous snapshot of birdlife across the
continent for all to see. Anyone can watch as the tallies come in at
www.birdcount.orghttp://www.allaboutbirds.org/NetCommunity/page.redir?target=http%3a%2f%2fwww.birdcount.orgsrcid=32265srctid=1erid=5826788.
Organizers
hope to receive more than 100,000 checklists during the event, with tallies
of more than 600 bird species in all.

Last year’s participants reported more than 1.8 million American Robins, as
well as rarities such as the first Red-billed Tropicbird in the count’s
history.

“Whether people observe birds in backyards, parks, or wilderness areas, the
Great Backyard Bird Count is an opportunity to share their results at
www.birdcount.org ,” said Judy Braus, Audubon’s vice president of Education
and Centers. “It’s fun and rewarding for people of all ages and skill
levels--and it gets people outside!”

“When thousands of people all tell us what they’re seeing, we can detect
changes in birds’ numbers and locations from year to year,” said Dr. Janis
Dickinson, director of Citizen Science at the Cornell Lab of Ornithology.

“While this is the depths of winter in most of Canada and only the hardiest
birds brave the cold, understanding of trends in the distribution and
abundance at this time of year is important as well,” said Dr. George
Finney, president of Bird Studies Canada.

 *
*

Data from the Great Backyard Bird Count can provide an early signal of
changes in bird populations. Past counts showed a drop in reports of
American Crows after outbreaks of West Nile virus in 2003, a finding
consistent with studies showing crow populations declined by 50–75% in some
states. Maps from the count have also captured the paths of migrating
Sandhill Cranes and recorded the dramatic spread Eurasian Collared-Doves.
Introduced to the Bahamas in the 1970s, the species was reported in just 8
states during the 1999 GBBC. A decade later, it was reported in 39 states
and Canadian provinces.

“I have joined the Great Backyard Bird Count for the past three years and am
really looking forward to doing it again,” said participant Kathy Bucher of
Exira, Iowa. “I really enjoy nature and bird watching. My mother and I share
updates on the birds we see. It’s a fun hobby to share with a loved one!”

For more information, including bird-ID tips, instructions, and past
results,

The
count also includes a photo contest and a prize drawing for participants who
enter their bird checklists online.

[cobirds] Re: owls

[Scott Severs]

Hi Scott,

Some additional thoughts. One thought is the cyclic nature of the
populations of small owls including E. Screech-Owl, thus the species
may be in a low population cycle (due to a loss of prey species,
predators) and it could rebound.  With the continuing urbanization of
the Front Range, Boulder's habitats may be increasing isolated from
regions that support possibly more stable populations of this species.
New recruits may not be finding their way into suitable habitats
around Boulder. I also think I personally seeing a continuing loss of
mature cottonwoods in the Boulder/St. Vrain Creek drainages, further
limiting potential nest sites for this species. There once were stands
of cottonwoods that seemed to provide a dense closed canopy along the
creek. Now it seems like only crack willows remain in places where I
use to detect E. Screech-Owls in cottonwood stands.

Time will tell. An interesting subject.

Best,

Scott Severs

[cobirds] saturday 1/1/11 birds

[Scott Severs]

A chilly AM jog at Harper Lake in Louisville produced some good looks at
several dozen Cackling-type geese mixed in with several Canada Geese. A
brief stop at Teller Farms Lake No. 5 found the imm. Golden-crowned Sparrow
continuing to winter with White-crowned and Song Sparrows. A second-year
Bald Eagle, Harlan's Hawk, and some Brewer's Blackbirds were also around.

Happy New Year!

[cobirds] Golden-crowned Swamp Sparrows, etc. Boulder 12/19

[Scott Severs]

The imm. Golden-crowned Sparrow continues in the windbreak junipers at
Teller Farms Open Space parking lot off Valmont Rd. added today to the
Boulder CBC. A Swamp Sparrow was in the marsh on the east side of Teller
Lake. Two distinctly different Harlan's Hawks at either end of the trail
(Valmont and Arapahoe trailheads).  Also alerted to by a mob of birds, a N.
Saw-whet Owl at a private residence. Snapshots of the bird at this link:

In Lyons yesterday during the Longmont CBC, no less than four Winter Wrens
that we tried to divine a least one into Pacific, but seemingly just not
enough evidence. Plus no less than 35 American Dippers, mostly in the city
limits of Lyons in the St. Vrain River.

Good CBCing!

[cobirds] Re: Nunn CBC Partial Results/Weld

[Scott Severs]

Interesting late shrike, which led me to remember a recent post by
David Sibley on the overlap between the ID of the two species,
especially immature Loggerheads and adult Northerns. See the post
here:

http://www.sibleyguides.com/2010/12/a-perplexing-shrike/

I'm not questioning anyone's ID, how could I, as I was not there. But
I thought people might enjoy Sibley's article, as it was a sort of an
eye opener for my own observations of these two species.

Sincerely,

Scott Severs,

[cobirds] Krider's Red-tailed Hawk, Boulder 12/16

[Scott Severs]

A very white-headed adult Red-tailed Hawk was perched along 75th Street,
Boulder, today just north of Munson's Farm on the west side of the road.
Field marks were very good for Krider's form. Very striking.

Good CBCing!

[cobirds] Boulder Orange-crowned Warbler 12/8

[Scott Severs]

The tardy Orange-crowned Warbler visited the aspen trees outside my office
again (Pearl East Circle) on Weds. with a mixed flock including a
Ruby-crowned Kinglet, several Black-capped Chickadees, a couple of Brown
Creepers, and a Mountain Chickadee. It slightly dinged itself into a window,
but was soon moving actively again after a few seconds.

While it's easy to discount office parks during the CBC, the abundance of
ornamental plantings have been especially rewarding in past years harboring
Bohemian Waxwing, Red Crossbill, Palm and Pine Warblers, plus many others.
So if your section of a count circle is especially urbanized, super
landscaped office parks might yield some surprises.

Good CBCing!

[cobirds] CBRC and ebird.org?

[Scott Severs]

Great post Ted,

I'm interested in how CBRC treats submissions to ebird.org which is
generally my favored way of contributing to avifauna data. The ebird
database is building an incredible depository of bird trends and
general data across the US and now an ever growing number of world
locations.

If CBRC uses ebird submissions, it there a way to make these
submissions more effective?

Hopefully more people will use ebird. It's really quite fun, and your
sightings add to bird knowledge and not locked away in a personal
journal. But if not, alas, that is birding, the ways of participating
are as varied as the birds themselves!

Ted - thank you for cracking the whip!

 Hello, Birders.

 Nick Komar says:

  Needless to say, the number of Black-legged Kittiwakes reported in
  Colorado this fall has been incredible.

 That's great. And I hope folks will be able to look back 5 years from now, or 
 50 years from now or even 500 years from now, and be able to appreciate what 
 Nick is saying. But here's the kicker: In order for Nick's impression to be 
 validated, there needs to be a formal record of all these kittiwakes. And 
 that can be accomplished only by submitting documentation of these kittiwake 
 sightings to the Colorado Bird Records Committee (CBRC).

[cobirds] birder economics

[Scott Severs]

I think the main premise of the article Hugh posted from Birding was to try
to spark a new way to find birders to be more of an economic force. User
fees, stamps and the like have generally lost traction. If birders were more
of an economic force, agencies, parks, private landowners, etc. would take
the birding community seriously by recognizing the value of birders and in
turn the value of preserving the birds and the places the birds need to
survive.

It's unfortunate that birders haven't really realized the potential force
for conservation that the community could be with a third of Americans
calling themselves bird watchers. Maybe there are too many groups pulling
people in many directions (I think I belong to 4 or 5). Whereas a small
hunting advocacy group, Ducks Unlimited, has probably done more for bird
habitat in North America with nearly 60 million acres of wetlands conserved.
Thankfully we have groups like ABC, RMBO, Audubon and Cornell working for
the rest of the avifauna, and they do a great deal with budgets that are
very limited.

Thanks for the interesting discussion,

Fwd. Golden-crowned sparrow update
   Posted by: stephen jones curle...@comcast.net
   Date: Wed Dec 1, 2010 10:45 am ((PST))

Monday morning we recorded this month's Nature Almanac radio spot at the Red
Rocks Trading Post, right at the base of Red Rocks Amphitheater. It will be
played on KGNU, 88.5 FM and 1390 AM, Friday morning a few minutes after 8
a.m.



The male golden-crowned sparrow who overwintered last year in the thicket
surrounding the feeder behind the Trading Post was quite visible, as was the
curve-billed thrasher. We also saw a Harris's sparrow, a song sparrow, and
the usual hordes of flickers, scrub jays, chickadees, and juncos. Best
viewing is from the high porch behind the Trading Post.



To listen to this (after Friday) and other Nature Almanac recordings, visit

[cobirds] Tundra Swans, Boulder Res. 11/24

[Scott Severs]

A pair of adult Tundra Swans were in the SW corner of the reservoir this AM
before being flushed by people running their dogs. They were last seen about
0745 headed NE toward Dodd Reservoir.

Six mile reservoir had an amazing number of Red-breasted and Common
Mergansers present. There were a lot of gulls, with Ring-billed of course
and Herring, but I could have missed others.

[cobirds] Important source of funding for birds up for renewal

[Scott Severs]

Hi Birders,

An important source for funding for migratory bird conservation is up for
renewal in Congress. Please consider taking a moment of your time to show
your support for all the birds that you personally enjoyed over the past
year. The bipartisan Neotropical Migratory Bird Conservation Act (NMBCA) is
the only federal U.S. grants program specifically dedicated to the
conservation of our migrant birds that is available throughout the Americas.
It has a proven track-record of success since 2002, advancing conservation
for many declining species, such as the Cerulean Warbler.

It only takes a moment and much easier than seeing a Ross's Gull! :) The
American Bird Conservancy (a very good organization) has an easy link here:

http://org2.democracyinaction.org/o/5400/p/dia/action/public/?action_KEY=4721

Thank you!

[cobirds] Cherry Creek Res. 11/21, more satisfied birders

[Scott Severs]

Marlene Bruning and I drove down from Boulder County to take our chances on
the Ross's Gull show. We found the birders watching and scanning from the
Lake Loop around 9 AM and saw a scope bird flying along the dam and then
alighting in front of the dam. We followed the vehicle procession to the
very NW corner of the lake, and as Bob Andrews described, and further
described today by Joe Roller, headed out on the trail below the dam to find
the bird on a tiny sandbar where we got very good views of the bird. This is
a great spot. Bring some coffee and a chair, because this is becoming a
reliable spot.

When it flew around the northwest corner a little later, it seemed to pluck
a morsel from the lake, and was pursued by Ring-billed Gull that wanted to
take its food, the tiny gull easily powered up and higher from the chaser as
to swallow its catch.

The cold front that came in later was an amazing change of conditions on the
lake from a balmy 54 to 30 degrees in about an hour. A huge flock of
pelicans swirled above with gulls and geese, including one Snow Goose.

Later- another birder pointed out a dowitcher near the bird deck, we spotted
a Harlan's Hawk soaring south of the reservoir, and we finally found a
Pacific Loon near the northeast corner of the lake.

Birder optic value estimate at 10:00am easily $75,000 if not $100,000! :)
How things have changed!

If any birders captured photos on the sand bar today, I would love to see
them.

Thanks to Joe, Glenn, and Cole for finding and sharing this cool bird, and
with countless other birders helping people today with seeing the bird.

Sincerely,
--

[cobirds] Boulder County, Snow Geese 11/21

[Scott Severs]

Not a rarity, but as I returned from Cherry Creek I spotted about 75 Snow
Geese flying over SW Longmont likely right over Schmoker's house at around
3:30 pm. Generally we don't see large flocks of this species in Boulder
County. Looks like they might have come from McIntosh Res. directly north of
my house as the goose flies. A few Cacklers were with them.

Rick Hatfield, Boulder OSMP Ranger

With 30 years experience monitoring raptors in the
Boulder area, Rick Hatfield has not only accumulated
knowledge about these birds, but also an appreciation
for how the Flatirons and the birds that live there contribute
to our sense of place and enrich our community.
He’ll concentrate on the cliff-nesting raptors and share
stories of the volunteer monitoring efforts to learn more
about the awesome creatures that call the Flatirons
home.

Unless otherwise noted, these events are held at the Unitarian Universalist
Church of Boulder, 5001 Pennsylvania Ave. (off 55th St. between Arapahoe and
Baseline) and begin at 7:30 PM.

AND available at the program: The Boulder County Checklist of Birds has been
revised and updated by Gillian and Alex Brown, with the help of George
Oetzel, and the contributions of many outstanding local birders and
naturalists (Floyd, Gent, Hallock, Jones, Kaempfer, Schmoker, to name a few,
but knowing there are a great many more!). It is a excellent resource with
months and habitats of occurrence and breeding. Cost $1 to recover printing
costs and available during before the meeting starting at 6PM during BCAS
annual holiday fundraiser. Also will be available on BCAS field trips.

[cobirds] Golden-crowned Sparrow, Boulder, 11/16

[Scott Severs]

A first year Golden-crowned Sparrow was at the Teller Farms parking lot off
Valmont Rd. More specifically feeding with White-crowned Sparrows in the
road/trail leading south from the lot where the juniper wind break abuts the
fence line. Kinda funny because it was the first bird I put my bins on. A
overflight of five Evening Grosbeaks headed toward the Cushmans was a nice
surprise. I ran out of time to look for the Harlan's Harris's Sparrow.

[cobirds] Winter Wren - Boulder 11/10

[Scott Severs]

Hi birders,

A Winter Wren briefly blasted its song this morning on the Boulder Creek
Path west of 75th Street. It was next to the creek, where the path turns
south toward the water treatment plant. I did not see the bird so I relied
on the musical quality of the song, as well as my experience with the song
of this species in Vermont, and *pacificus *on the Olympic Peninsula.
Phishing and patience did not produce a visual and it did not vocalize
again. There were nice mixed species flocks of B-c Chickadees, Brown
Creepers, R-c Kinglets, W-b nuthatches etc. working the riparian vegetation.
An American Dipper was also singing near a traditional winter territory on
the creek. A late Greater Yellowlegs was in the private pond west of the
plant. A Sharpy quieted everyone down, and then dove amongst the pipes and
infrastructure of the treatment basis maybe trying to surprise something.

Good birding!

[cobirds] in praise of an important reference, nearly 2 decades later

[Scott Severs]

Some references consistently withstand the test of time, and this is true of
Andrews and Righters Colorado Birds published in 1992. While I really
enjoy the expanding electronic media of bird knowledge, Colorado Birds is
always within arms reach to lend some clarity to bird distribution in the
state.

And while information and species ranges are constantly in flux, overall
distributions of most species have not greatly changed and Colorado Birds
remains a relevant and enjoyable reference, and a most important reference
for Colorado birders even today. We are lucky to have it.

In appreciation!

[cobirds] Bob Andrews talk: Boulder 10/21, 7 PM

[Scott Severs]

Thursday, October 21, 7:00 p.m. Uganda: Life in the Pearl of Africa
George Reynolds Branch Library

Uganda – the Pearl of Africa – is a land of friendly and gentle people,
moderate climate, scenic lakes, rivers, hills, and mountains and stunning
biodiversity, but also with a harsh history and stubborn poverty. In this
program, Bob Andrews will discuss the educational work he did for four years
at a small college, introduce the daily life of rural Uganda, and give a
sampling of Uganda’s rich flora and fauna.

Bob Andrews, born and raised in Denver and currently living in Englewood, is
a long-time Colorado field ornithologist and naturalist. He has led many
birding field trips and is the senior author of Colorado Birds. He graduated
from the University of Colorado with a Master’s in biology. He lived in
Africa for 13 years, 9 years in Namibia and 4 years in Uganda, where he was
a biology and geography lecturer, Academic Registrar, and Assistant
Vice-Chancellor at Central Buganda University.

[cobirds] Migration notes: Cheyenne Co. 9/27 28 (pipits)

[Scott Severs]

Hi birders,

Work on private land yielded a good push of prairie migrants including large
flocks of Chestnut-collared Longspurs, Swainson's Hawks, a few Ferruginous
Hawks, and over two days, groups of Sprague's Pipits (9/27  9/28). At one
point I saw three in view, and hearda forth all in short grass prairie. I
likely heard others and if folks were to look along roads in good prairie
east of Cheyenne Wells I think this is a good time to find some (see the
Colorado Birding Trail website). Actually I was surprised how many I
encountered, but maybe it's the Kansas effect. Unfortunately I could not
gain public access. Here are some snapshots:

Yet if you might be a Boulder basher :), look at the great finds Christian
has found where the City of Boulder has preserved habitat! So you may not
have to go to Kansas! Yeah! Open Space!

Good birding,

[cobirds] two more Broadies - Boulder County 9/25 26

[Scott Severs]

Hi birders,

Corresponding to this species continental latitudinal peak or slightly past,
Broad-winged Hawk migration is in full swing and I observed one yesterday
during a mini raptor migration watch at Bald Mtn Open Space, and another one
(juv.) this morning in SW Longmont.

At Bald Mtn, here are the results of a mini six hour raptor migration watch:

Turkey Vulture, 10
Osprey, 1 adl f
Northern Harrier, 1 adl f
Sharp-shinned Hawk, 1 juv.
Cooper's Hawk, 4 adl, 2 juv. (2 locals)
Broad-winged Hawk, 1 adl
Red-tailed Hawk, 6 adl, 1 juv. (5 locals)
American Kestrel, 3 f, 2 m

Bald Mountain was right at the eastern edge of the Four Mile Canyon burn
zone, and many Western Bluebirds were foraging directly in the burned ground
below the pines. What were they eating?

Bald Mountain Scenic Area is located 5 miles west of Boulder on the south
side of Sunshine Canyon Drive (County Road 52).

Good migration,

[cobirds] Turkey Vulture super-roost Longmont 9/24

[Scott Severs]

Hi birders,

Having found other species roosting with TVs during migration (Broad-winged,
Swainson's Hawks), I visited the Longmont TV roost at dusk on Friday, 9/24.
I arrived too late to see the fly-in and did not see other species, but the
roost contained at minimum 120 TVs and likely many more. They especially
like to perch in blue spruce trees, and a few old elms. Roost is
approximately one block with the SE corner starting at 6th and Lincoln. Very
cool, but maybe not so much for the neighbors!

[cobirds] Sabine's Gull Pacific Loon, McIntosh Lake, Longmont 9/5

[Scott Severs]

A visit to the lake this morning yielded a adult Sabine's Gull (and possibly
a second bird which I lost) flying along the northern shore, and the Pacific
Loon foraging in the western half of the lake. Plus lots of pelicans, Great
Egrets, and other common birds. Water is down more, but no extensive mud
flats yet. Barn Swallows abundant, Cliff Swallows, ever-present this summer
not to be seen.

Good Birding,

[cobirds] David Sibley takes on crossbill identification.

[Scott Severs]

David Sibley has an interesting article on his blog today, working through
crossbill identification with the help of Nathan Pieplow.

Interesting stuff:

[cobirds] Pacific Loon still present at McIntosh Lake, 9/2

[Scott Severs]

Plus egrets, a lone Clark's Grebe, a trio of Ruddy Ducks,  migrant Bank
Swallows, and a White-crowned Sparrow, etc.

If they are drawing down water, it's barely evident. Shorebirds consisted of
a lone Least Sandpiper, Killdeer, and Spotted Sandpipers. Plus some
unidentified high flyers that could not be enticed to land.

Loon diving frequently as recently reported.

[cobirds] program: Limber Pine and Clark’s Nutcrac kers, Pine Beetles and Blister Rust, 9/9/2010

[Scott Severs]

The following program may be of interest to some of you. From the Boulder
chapter of the Colorado Native Plant Society.

Jeffry Mitton: Limber Pine and Clark’s Nutcrackers, Pine Beetles and Blister
Rust

Limber pine and Clark’s nutcracker are in a co-dependent relationship that
has evolved over time: Limber pines rely on nutcrackers to harvest, disperse
and plant their seeds, while nutcrackers rely on limber pine seeds to get
through the winter. This mutualism is threatened by an unprecedented
mountain pine beetle epidemic and the invasion of white pine blister rust.

Jeff Mitton started as an assistant professor in the Department of Ecology
and Evolutionary Biology at CU in 1974, where he is now professor.  Mitton’s
research interests focus on the genetics of natural populations of plants
and animals. He has worked on marine and freshwater mussels, killifish,
trout, pines, aspen, and spruce.

Mitton writes a biweekly column entitled “Natural Selections” for the
Boulder Camera, which describes the natural history and ecological
interactions of plants and animals in Colorado.

Programs for the Boulder chapter of the Colorado Native Plant Society are
held on the second Thursday of the month, September through April, in the
community room at REI, in Boulder at 1789 28th Street.

[cobirds] Additional Uppies - Adams County 8/27 8/31

[Scott Severs]

I was lucky enough to encounter two Upland Sandpipers recently in the mist
of avian surveys. One on Friday 8/27 alighted in a prairie dog town about an
hour after dawn and began foraging while emanating a couple of calls, and
this morning 8/31, also about an hour or so after dawn one was heard
overhead headed eastward. Detections were near the Todd Creek golf course.
Both were detected by ear first, thanks to Ted's link to the flight call on
xeno-canto. I also saw the tail ends of a flock of mystery shorebirds,
unfortunately too far away and saw them too late to get an ID. Large groups
of Snowy Egrets exploiting the ponds at Todd Creek golf course. A Greater
Yellowlegs also called overhead flying southward.

Happy migration,

[cobirds] helping birds impacted by the Gulf Oil Spill

[Scott Severs]

Hi Birders,

While this issue is not in Colorado, this deepening catastrophe will impact
many of our birds that winter in the Gulf including some of my favorites
such as American White Pelican, Long-billed Curlew, Osprey and many other
shorebirds and birds that winter in the Gulf and pass through Colorado
(terns, jaegers and loons).

Plus the Gulf is a destination spot for many of us to see Whooping Cranes
and all the other local species that make it a great birding destination. So
this oil spill is a Colorado, and national issue of major bird significance.
The Brown Pelicans that occasionally turn up here are likely from the Gulf.

Here are two bird friendly places to help:
