Visitors:
Ten visitors to the platform; five were curious. Gave out three Dino HW business cards. One was a science/math teacher from North Carolina on vacation. Helping us count:
Weather:
Wind shifts were all over the place today, but most from the east; northeast, southeast. There periods of no windâ€"and no migrating birds. Winds picked up, migrators the same. Mid watch, flightpaths shifted from high over the foothills to low on both sides and overtop of the ridge. Weather station: Dark Skies app.
Raptor Observations:
Locals: RTHA 4. Two seen copulating on the pole next to the race track. All four hung around all day. Local TUVUs: 7. Local BAEA? 1. MIGRATORS: One migrating BAEA was first year. Migrating TUVUs were mostly on the west side of the ridge just above eye level and came in droves; then mostly in pairs. AMKEs appeared suddenly mostly on the east side of the ridge, close by. MERLs followed the west side of the ridge.
Non-raptor Observations:
Rock pigeon: 1. Black-billed Magies: 3. Sandhill Crane: 1 going northbound. Spotted Towhee: 1. House finches: 4. Common Ravens: 6. White-throated Swifts: 9. Woodhouse’s Scrub Jay: 3.
Predictions:
It gets chilly in the wind on the platform. Since my last trip up the hill, Jefferson County has posted a CLOSED sign on the fence at the back of the platform, along with dozens of big branches and rocks to prevent using that alternate site and trail. They also seem to have left orange cones and a lawn chair under the juniper tree. What’s up with that?

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 of any skill level are always welcome.
HawkWatch at Dinosaur Ridge is generally staffed by volunteers 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
southwest end of lot to the 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 ridge.
