The weather helped make it a great day for watching, but mainly it was
having Cindy Johnson and Gary Rossmiller there most of the time that made
the day.

Only a couple of curiosity seekers on the hill today in spite of the good

Today was a great day for watching; given the great weather, surprisingly
not that great for seeing; or hearing (the motocross track was especially
loud this morning with some kind of event starting in the early hours).
Green mountain and Mt Morrison started out with a dust of remaining snow
and the trail up was muddy (as advertized). All gone by end of watch. A
cold breeze from the southeast picked up around 9:00 am MST and persisted
generally from the east most of the day. Cotton ball cumulus clouds then
rose by 10:00 MST on the east and south horizon and stayed there most of
the day. Directly overhead was mostly intensely dark blue and crystal
clear. Visibility to the south was awesome. From 1:00-2:00 MST the wind
died down and late in that hour we spotted a migrating Sharp-shinned Hawk
and American Kestrel. (WUnderground station all day was Solterra.)

Raptor Observations:
Local American Kestrel (male) hovered over Rooney Road and mid way up the
east side of the ridge for about 5 minutes early in the watch. Great fun to
watch. Local dark Red-tailed Hawk escorted light RTHA migrator. Pattern
today seemed to be riding thermals over Two Humps to Apex, then turn back
or southwest. Later in the watch, a Sharp-shinned Hawk circled high down
ridge and spiraled consistently (accompanied by two local Red-taileds)
north but then vanished beyond 10x binoc range just overhead in clear blue
sky. Counted, but made us wonder if other migrators escaped without notice
at high altitude beyond visual range. But with clear skies and three
experienced watchers, including a scope, unlikely. An immature Golden Eagle
circled Red Rocks and moved north, caught a thermal by Cabrini, then turned
back south. We speculated it was escorting the migrating Bald Eagle (which
would not be the first time i've seen a senior being escorted by a youngin
in the news). Non-migrating raptors: GOEA (1), AMKE (2), RTHA (6).

Non-raptor Observations:
A couple of Monarch Butterflies criss-crossed the platform. NON-RAPTORS
SEEN OR HEARD: Northern Flicker (3), Woodhouse's Scrub-Jay (3),
Black-billed Magpie (4), Black-capped Chickadee (1), Western Bluebird (1),
Townsend's Solitaire (3), Spotted Towhee (5) heard all day, Western
Meadowlark (2). All reported on eBird.

Expect good weather and a mostly dry trail up from the Stego lot. Tell me a
better way to spend a day than being a citizen scientist – in Colorado!

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 Bird Conservancy of
the Rockies 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 south side of lot to 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
