Re: [cobirds] Possible Slaty-backed Gull, Larimer

[ColimaBirder]

Most lariphiles agree some first cycle pale-headed gulls are challenging.
So much variation.
Can you you elaborate on those “checked boxes” you mention?

[cobirds] Fremont county, osprey

[Laura Gorman]

A pair of osprey were occupying the nest platform on Mackenzie Rd. today. 
 There are numerous Great Blue Herons on nests further south on Mackenzie 
Rd. at the River.  The Great Horned Owl is back on the nest along the 
Riverwalk, between Sell and Reynolds.

[cobirds] A goose trifecta - Akron -Washington County

['DuWayne Worthington' via Colorado Birds]

On my way to try and find the greater prairie chickens (which didn't
happen), I ran across 24 greater white-fronted geese, 120 snow geese, and
22 or so cackling geese in one of the farmer's fields on country road X
around 7:30 am.  The cackling and greater white-fronted were mixed together
right by the road, and the snow geese were just behind them a little
further into the field.

[cobirds] Lagerman Res on a windy Sunday + E Kingbird

[Kat Bradley-Bennett]

A blustery walk around Lagerman Reservoir today yielded about 20 Ruddy 
Ducks, a couple of Cinnamon Teal, 3 Red-breasted Mergansers, about 6 
Buffleheads, and about 20 Ring-necked Ducks. Both Osprey were present, as 
were the two Bald Eagles nesting to the south. A male Northern Harrier was 
hunting just west of the Osprey platform. The treat of the day was a FOS 
Eastern Kingbird holding its own in the wind on the south side of the 
reservoir.

Observation start time: 09:15:00 
Observation end   time: 13:30:00 
Total observation time: 4.25 hours

Official Counter:Gary Rossmiller

Observers:Aaron Shipe, Janet Peters, Mark Chavez, Vonnie Robinson

Visitors:
Aaron Shipe and Mark Chavez were on site until 11am, helped spotting. Trail
very to extremely busy today, including 3 electric unicyclists coming onto
the platform from the back way and then continuing south down the stairs. 


Weather:
WOW! Wind changed direction almost hourly, from the east then the west,
gusting to B6 out of the west. Almost calm at times, B2-3 common. Overcast
skies, improving during the day, but sun never really came out. Horizons
blue in all directions. Temps from 7.7C up to 16.1C, barometer falling
slightly 24.73in to 24.70in.


Raptor Observations:
Very slow, most flights overhead, one UA very low to the west. 1st TV's
recorded, saw 2 circling over Hwy 6 on the way to site, also. Local RT pair
fairly active showing off how to handle the high winds. One local TV going
SE past Green Mountain. 

Non-raptor Observations:
Elk above I-70, Swift, Bush Tit, Solitaire, Crows, Ravens, Magpies, Robins.
Very few flights of local birds. Trail is almost dry, still some muddy
areas.

Predictions:
Dunno, with this weather changing so much.

Dinosaur Ridge - Denver Field Ornithologists information may be found at:
http://www.dfobirds.org


More site information at hawkcount.org:  
https://hawkcount.org/siteinfo.php?rsite=123

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 of any skill level are always welcome.  HawkWatch at
Dinosaur Ridge is generally staffed by volunteers from about 9 AM to around
3 PM from March 1st to May 7th.

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 southwest end of lot to the hawkwatch site. The hike starts heading
east on an old two-track and quickly turns south onto a trail on the west
side of the ridge. When the trail nears the top of the ridge, turn left,
head through the gate, and walk to the clearly-visible, flat area at the
crest of the ridge.  (Distance: 0.56 miles, Elevation gain: 259 feet)

[cobirds] Sandhill Cranes over Littleton, Arapahoe Co

[David Suddjian]

About 140 *Sandhill Cranes* were just circling over the area of St. Mary
Church along Prince Street in Littleton, moving north. It was great to see
(and hear!) them, as the local skies had been empty all day, despite nice
conditions.
