Little traffic on the trails though Pat Connor, JeffCo Open Space and
former Hawk Watch volunteer stopped by to check in and watch the skies for
a bit.

The morning began with a slight breeze from the west and near calm sunny
conditions. Eventually the wind came from the east and during the noon
hour it became very strong and swirling at the site. The sun remained out
and temps reached 66F.

Raptor Observations:
The local Red tails were very active all day and even shared an intimate
moment on the power lines to the east. I did observe an unidentified
falcon early in the morning flying near some of the local Red tails but
it's path went straight east until it disappeared on the south side of
Green Mountain. The migrating birds observed came from the Mtn
Morrison/Two Pines area and for the most part were very high up.

Non-raptor Observations:
Blue birds!! Several groups flew right past or right through the platform.
The Scrub Jays were very vocal and busy and some were carrying sticks when
they flew over. Townsend's Solitaires, Magpies, and Chickadees
(Black-capped?) were hanging out as well.

No thoughts on predictions for tomorrow but I would say that between today
and my last day up it seems that when you see one moving through there will
be a couple accompanying bringing up the rear.

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
