Visitors:
Around 6 who came and asked questions answered by our able volunteers.
Weather:
I was pleased we had some cloud cover especially to the south which gave us half a chance to find the migrants in the sky. For specific hourly weather data see my report at hawkcount.org
Raptor Observations:
The 1st migrants were 4 TV at 9:51 AM MST. Perhaps the best sightings of the day for me were 2 distant buteos to the south which I was able to get my scope on and could see their white tails = adult FH, also a distant dark morph adult FH. Almost all the raptors were far to the west with only 6 overhead and only one to the East â€" a TV found by Martha, and who also found us the ML flying like "a bat out of hell" which no other migrant raptor could ever match. We had 3 kettles of 4 TV each. Non-migrant raptors: TV 4, RT 2.
Non-raptor Observations:
Rock Wren heard, White Pelican 5, American Crow 3, Common Raven 3, House Finch 1, Northern Flicker 1, Spotted Towhee 1, Woodhouse's Scrub-Jay 1. I was very pleased to see Carol and Steve show up to help me find and identity raptors, as I am still learning to get used to this watch with really distant migrants compared to what I was used to in New York where the raptors were much closer, and was gratified and reassured to find that they did not find a whole lot of migrants we were missing! Thanks to Natalie and Martha for finding raptors in the morning and Janet and Shmuel in the afternoon.
Predictions:
SW at 18 mph, 31 mph by noon and 40 mph by 3 PM â€" Carol thinks the count could be terminated early because of the strong winds.

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson’s hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. Northern Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, American White Pelican, and Dusky Grouse. Birders of any
skill level are always welcome. The hawk watch at Dinosaur Ridge is staffed by a
Hawk Counter and volunteers from 9:30 AM to 5:30 PM from March 1st to May 14th,
weather permitting.
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 hawk watch signs from the
southwest end of the parking lot to the hawk watch 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, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)
