Busy, busy, busy day on the trail. The morning started with some very loud
fly overs from 4 military jets. Lots of mountain bikers who, at one point,
got into a prolonged verbal argument on the platform. The gun range and
motorcycle course were in full gear as well. I believe out of the 30 or so
visitors only one curious hiker asked what we were doing up there.

Beautiful, clear sunny day on the hill. There was very little wind
throughout the morning and into the afternoon. A bad day to forget

Raptor Observations:
We observed a pair of Red Tails throughout the day from every possible
angle. They seem to be deeply in love, flying in tight circles and
dropping their legs multiple times. At one point we did see a third RTH
that was trying to make it into the circle but was chased off in a fun to
watch air battle. The third did not head north so maybe there's a lonely
guy in the area. The migrators were observed on both the east and west
sides of the platform and most did not leave any guesses to where they were

Non-raptor Observations:
Magpies, Townsend solitaires, doves, and a handful of Ravens were seen.
Jane Haddock witnessed a couple flocks of robins fly by as well.

Hopefully you'll get to see some variety. The first 3 RTHs were seen along
Mt. Morrison over to Two Pines so that maybe a favorite path this's probably quieter!

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
