Weather:
Today’s forecast at earth.nullschool.net was similar to that of the last
few days where there was a band of strong NW winds especially north of
Denver and less so at the watch. I felt that this would prevent any migrant
hawks flying southward East of the Front Range to the watch, and instead
push them to the east of Denver and away from the hawk watch. This is what
happened 2 days ago as well as today.
In the last hour today there was excellent cloud cover both overhead and
immediately to the north and west of the watch, in spite of which I could
find no migrating hawks.
Level 3 winds with gusts to Level 5 ("branches of moderate size move, small
trees with leaves begin to sway") from the W>NW, temperature 13-16°C,
humidity 24–19%, steady barometer, increasing cloud cover 15-50%, clear
visibility to 25 km.
Raptor Observations:
Non-migrant raptors: RT 3, AK in binoculars to the NW which flew to the
North and dropped.
Non-raptor Observations:
Townsend’s Solitaire 4, Woodhouse’s Scrub-Jay 1, Black-capped Chickadee
1, Common Raven 5, House Finch 1.
Predictions:
Tomorrow according to earth.nullschool.net the winds are predicted visually
to come streaming down from Canada in an NNW direction eventually turning
towards the hawk watch location from the NE, so perhaps there may be some
migration visible at the watch, perhaps later in the day.

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 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. (Distance: 0.56 miles, Elevation gain: 259 feet)
