Observation end time: 15:00:00
Total observation time: 6.75 hours

Official Counter: Gary Rossmiller

Observers: Bill Wuerthele, Earl Johnson, Paul Johnson

Visitors:
Earl Johnson came up at 10am, Bill Wuerthele at 11am. Earl's dad, Paul,
joined us after 1pm. Several people on the platform who stopped for the
view. And a mountain biker who hopped up the first two stairs without
stopping!
Earl and Bill were invaluable. Earl's quick spotting and ID made the
difference. And a huge camera lens helps to confirm an ID.


Weather:
Very pleasant day on the ridge; temps increasing from 4-18 c, falling
barometer 30.20"-30.10", breezy 2 bft with an occasional period to 5 bft.
Clear, hazy skies in the morning with increasing overcast as the day
progressed making raptor identification a bit harder. Skies were gray by
the end of the day walking down the trail.

Raptor Observations:
A lot of eyes on the sky helps to see a lot of birds!!
Very busy day, starting right away. A slight mid-day lull followed by an
active afternoon. SS, CH, Ospry, Peregrine, AK, Ferruginous, TV, a possible
Rough-Legged Hawk. A lot of Kestrels in the afternoon over the west ridge.
Not a lot of local activity except for the TV's. Morning raptors were very
close, increasing to very high and/or over the west ridge in the afternoon.

Non-raptor Observations:
Woodhouse Scrub Jay, Western Meadowlark, Townsend's Solitaire, Canyon Wren
(heard on the west side), Black-billed Magpie, Spotted Towhee, American
Crow, Common Raven, Black-capped Chickadee. A humming bird was heard.
Bushes are starting to green, grass hoppers are out.

Predictions:
Seems to be at the height of the season. More eyes seems to equal more
birds.

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
ridge.
