Official Counter: Mitchell Blystone

Observers: Graham Hill, Terry Escamilla

Having Terry and Graham on the hill helped immensely! More observant eyes
and the scope helped us up the count. Typical weekend traffic with a some
curious hikers asking questions. There was a lot of activity at the motor

HOT and DRY!!!! The morning began very warm with a slight breeze from the
south. Lots of sunshine and only high cirrus clouds which did little to
shade the ridge. The winds eventually came out of the southeast and became
more moderate than calm.

Raptor Observations:
A very quite morning with no sighting of even the locals until around
10:30am. Eventually the local active became near constant along the
Cabrini hillside and western ridge line. Some of the earlier migrating Red
tails were observed moving through the east valley and were slightly above
the platform. The later migrators including the falcon were very high up
and difficult to ID as well as follow. Two Red Tails took nearly identical
flight paths high along Mount Morrison and where barley visible when they
moved over Golden. There were a couple distant observations of what seemed
to be local Kestrels and even Accipiters but they were too distant to
confidently identify. A day of having to work hard for any kind of

Non-raptor Observations:
Many Townsend's, Magpies, Robins, Crows, and Ravens. There were a handful
of Towees (Spotted?) early on in the day and a couple times while observing
raptors there seemed to be White Throated Swifts moving quickly by but they
were distant and hard to follow.

Looks to be hot again so bring sunscreen and lots of water. A lot of the
migrating birds still seem to prefer to be high up along the Mount Morrison
ridge line. A scope would greatly increase your chances at identifying
these high flyers!

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
