Official Counter: Joyce Commercon

Observers: Hadi Soetrisno

Visitors:
Hadi Soetrisno, a HawkWatcher from the early days of Dinosaur Ridge’s
HawkWatch, spent the morning on the Ridge. His conversation and his help,
in spotting the few raptors that happened by, were very much appreciated.
Most other visitors to the Ridge were there only for the view or had lost
the path descending to the parking lot. One couple, however, that was met
on the trail in the early morning, was interested to know about the raptor
monitoring, and was curious to know if we were seeing Golden Eagles, Bald
Eagles and Turkey Vultures yet.


Weather:
The day was very warm with temperatures rising from 17 C to about 26 C
during the watch. Winds were initially mild from the east and southeast,
but became stronger (bft 3-4) and shifted to come from the west just before
noon MST. Cloud cover increased from 40 to over 90 percent. Thicker, often
grayer, clouds eventually replaced the patchy mix of flat cumulus and thin
cirrus clouds that paraded during the morning hours. Visibility was very
good.

Raptor Observations:
It was a slow day for migrating raptors. The highlight was an adult Bald
Eagle (spotted fairly high over Rooney Valley) that migrated northwest past
Bare Slope and Lookout Mountain. A good view of a northward-bound male
American Kestrel in the afternoon was also appreciated. Also in the
afternoon, a local adult Golden Eagle passed north of the HawkWatch site as
it moved eastward from West Ridge to Green Mountain and beyond. The local
Red-tailed Hawks were scarce early in the morning but became much more
active as the day progressed. Mostly, only one was seen at a time:
hovering, kiting, hunting—up and down the valleys, over Green Mountain and
the western ridges from Mount Morrison to Cabrini. Near the end of the
watch, one of the pair was observed to circle up from the trees along Mount
Vernon creek at Matthews/Winters Park. With a full crop, it headed
northwest, leisurely performing some shallow roller-coastering along the
way. Shortly afterward, the second of this presumed pair was seen still
hunting in the same valley; it soon also headed northwest.

Non-raptor Observations:
A Canyon Wren was heard twice today. A pair of Common Ravens rode the
increased winds near noon; one displayed its prowess by doing several
backflips. One of the many American Crows spotted today appeared to have
small white patches near its carpals. Also seen or heard were Spotted
Towhee, Woodhouse’s Scrub-Jay, Townsend’s Solitaire, Rock Pigeon, House
Finch, Western Meadowlark, Black-billed Magpie, Dark-eyed Junco, Northern
Flicker, and Western Bluebird.

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.
