Hardly any people on the trail today because the weather was so bad.  A
lady and man stopped by in the last hour and asked what I'd seen. 
Evidently years ago they had made a hike with Colorado Mnt. Club, stopped
at the station and got to see Swainson's Hawks migrate.  Wonder where they
are this year???? 

The Ridge and surrounding area got none of the snow that Central Denver
did.  It was dry, windy, cold and humidity made it bone-chilling today. 
The sky was 100% overcast, 100% of the time. 

Raptor Observations:
I had 3 Turkey Vultures and 1 Red Tail migrate as I was hiking up the
Ridge---glad I was there a little early.  All of the activity was on the
west side of the Ridge, with migrators flying into stiff headwinds.  The
last migrator of the day was a Turkey Vulture who had a heck of a time of
it, but after working the air for quite sometime, finally made it across
I-70 and on out of sight north.  Locals: 2 Red Tail Hawks; 8 Turkey
Vultures; 1 Cooper's Hawk.

Non-raptor Observations:
Other species seen or heard: 4 Black-billed Magpie; 2 Woodhouse's Scrub
Jay; 5 Townsend Solitaire; 2 Common Raven; and 5 swallow species that
swooped by very fast.  

Tomorrow's weather looks similar to today's, so maybe about the same as far
as migration is concerned.

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
