[cobirds] Black Phoebe at Fremont Sanitation District Plant in Florence

[SeEttaM .]

Yesterday I found a Black Phoebe in a tree behind the Fremont Sanitation
District Plant in Florence.  Black Phoebes have frequented this area
including the fencing around the plant  as well as the area where the tanks
are located for a number of years.  Last year a barrier was put up across
the dirt road that runs on the north side of the plant that says not to
enter as it is the property of the Sanitation District.  I have spoken with
a District official who has indicated that entry for birding by foot (still
cannot drive behind the barrier) is not a problem.  He has suggested I
speak with the Plant manager to explain what people with binoculars would
be doing there and I will do so on Monday.  The Sanitation District does
have high fencing around the Plant that must not be breached as this is
their security barrier.

The Florence River Park is just to the north of the Sanitation Plant and
those who not been there recently will find that they have made some big
changes.  At this point vehicles are not permitted beyond the parking lot
just across the wetlands.  However they are in the process of adding stone
fencing going back to the rear part of the park that will allow vehicles on
the road but not tearing up the vegetation as has occurred in the past few
years.

[cobirds] Video clips of Sandhill Cranes feeding before leaving Canon City

[SeEttaM .]

I got to watch the family of Sandhill Cranes that spent the week in Canon
City as they fed in an ag field that had manure spread over it last week.
They were close enough I could see them using their bills to pick through
the clumps of manure as they searched for insects and grain.  I got two
pretty short video clips of this feeding behavior I have uploaded to my Birds
and Nature blog .  Also on my blog are
some photos of them yesterday as they circled and gained altitude to
apparently resume their migration north.

[cobirds] Roaring Fork Saturday

[Dick Filby]

Hi all

 

At home our Harris's Sparrow and Pinyon Jays continue to visit. Upvalley, at
Snowmass Ski area (Pitkin), my 'free bird tour' guests were treated to over
200 Rosy-Finches of all three species, mainly Browncaps, as well as Gray
Jays and a couple of Pine Squirrels muscling in on the free food!

 

Downvalley, late afternoon, there were 58 Barrow's Goldeneyes on the private
ponds at Coryell Ranch, viewable from the nearby County Road. 

 

Good birding all

 

Dick Filby

Observation start time: 08:30:00 
Observation end   time: 14:00:00 
Total observation time: 5.25 hours

Official Counter:Lee Farrell

Observers:Dave Spates, Linda Farrell, Roger Rouch

Visitors:
Hearty runners and mountain bikers were out getting their exercise on the
trails today. A Boy Scout Troop stopped by the station while on their 5
mile hike. We discussed the migration count and birding in general with
some of the troop leaders. 


Weather:
Overcast skies, high winds and cool temperatures made for a challenging day
on the hill. Winds of 20 MPH and more were out of the northwest for most of
the morning. Around noontime they switched around to the north-northeast
while remaining strong. Throughout the day a moderately high cloud layer
was present over most of the sky. Around noon, a line of lower cumulus
clouds developed over the metro area to the west, later dropping rain and
snow to the southeast. Temperatures remained in the low 40s(F) throughout
the day.

Raptor Observations:
High winds kept most of the migrating birds relatively close to the ridge
today. Determination of resident vs migrating birds was occasionally
complicated by the high winds. Local Red-tailed Hawks traveled up and down
the ridge area, at times performed mating displays.

Non-raptor Observations:
Other bird species observed today included: House Finch, American Crow,
Common Raven, Black-billed Magpie, Mountain Bluebird, American Robin,
Townsend's Solitaire, and Western Scrub Jay.  

Predictions:
No telling how the birds might react, but the predicted clear skies, low
winds and warmer temperatures should be favorable to good birdwatching. 

Report submitted by Rocky Mountain Bird Observatory (jeff.bi...@rmbo.org)
Dinosaur Ridge information may be found at:
http://www.rmbo.org/


Site Description:
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Dinosaur
Ridge may be the best place in the country to see the rare dark morph of
the Broad-winged Hawk (a few are seen each spring). Hawkwatchers who linger
long enough may see resident Golden Eagles, Red-tailed Hawks and Prairie
Falcons, in addition to migrating Swainson's, Cooper's and Sharp-shinned
Hawks, American Kestrels and Turkey Vultures. Peregrine Falcons and
Ferruginous Hawks are uncommon; Northern Goshawk is rare but regular.
Non-raptor species include Rock Wren, and sometimes Bushtit, Western
Bluebird, Sandhill Crane, White-throated Swift, American White Pelican or
Dusky Grouse. Birders are always welcome. 
The hawkwatch is generally staffed by volunteers from the Rocky Mountain
Bird Observatory from about 9 AM to around 4 PM from the first week of
March to the first week of May.

Directions to site:
>From exit 259 on I-70 towards Morrison, drive south under freeway and take
left into first parking lot, the Stegosaurus lot. Follow small signs from
the south side of lot to hawkwatch site. The hike starts heading east on an
old 

[cobirds] Walker, wind & wigeon (Eurasian) - Douglas

[Hugh Kingery]

Urling, at the Walker Pit, in the roaring wind, spotted a striking male 
Eurasian Wigeon. It's hanging out with other wigeons, who don't particularly 
cotton to it. Urling didn't think any females connected with it. 11:45-12:15 

Directions: a quarter to a half mile west of the Franktown traffic light, on 
Colo. 86, turn north on Walker Road. Viewing area a half-mile straight ahead. 
We saw it on the west side.

Re: [cobirds] Common Nighthawk

[Nathan Pieplow]

I am unaware that Common Goldeneyes ever give their nighthawk-like calls in
flight or at night.  These are not the equivalent of other duck quacks; I
believe they are only given by males displaying on the water, while
throwing their heads back.  Many ducks do give display sounds during
courtship chase flights, but I think this would be quite unlikely at night
or at high altitude in any species, and BNA's description of the display
flight in Common Goldeneye appears to correspond to the very short-range
"leapfrogging" flight I've seen them do from the back to the front of
courting groups on the water, without vocalizing.  Furthermore, male Common
Goldeneyes make loud whistles with their wings in flight (usually?
always?), and if you were close enough to hear the call, you likely would
have been close enough to hear the wing whistles as well.

If the sound came from high in the air, we may be able to rule out American
Woodcock as well, because according to BNA and Sibley, they only make those
nighthawk-like "peent" sounds from the ground, BEFORE taking to the wing in
their nocturnal display flights.  The sounds they make in the air are
high-pitched chirping twitters (made by their wings).

If you hear a Common Nighthawk in Colorado prior to late May, there's an
extremely good chance you're hearing an imitation, probably by European
Starlings, which have fooled me several times -- at least during the day.
A call from high altitude at night is more consistent with a nighthawk, but
the date is more than eight weeks earlier than the species would be
expected in the area.

Re: [cobirds] Common Nighthawk

[Greg Pasquariello]

That's interesting, I hadn't considered that.  I just listened to a recording 
and I concur; they do sound similar.  I don't have enough of the memory to say 
that was what I heard, but it's certainly more likely than either a 2 month 
early nighthawk or a woodcock.

The call was fairly high (altitude-wise) and that helped it sound very much 
like a nighthawk, but there's no reason it couldn't have been a passing 
goldeneye.

Re: [cobirds] Common Nighthawk

Co birders,

The other very real possibility is common goldeneyes flying up the river 
calling.  They can sound almost exactly like common nighthawks.
