Official Counter | Mike Fernandez |
Observers: | David Gulbenkian, Jeff Wang |
Visitors:Jeff Wang held watch from 0700-0900 MST, reporting a local Red-tailed. Then
about noon MST, David Gulbenkian arrived to help. Mitchell Blystone, out
for a hike and a day off stopped by to say hello at 1130 MST. Thanks
Mitchell, what committment! One runner (describing herself as a beginner
birder) asked about what we were doing and took a DinoHawk card. Jeff and
David departed at 1300 MST.
Sidebar: Matthews-Winters was closed today due to muddy trails (sign read:
Closed for resource protection and visitor safety due to muddy trails;
strictly enforced, minimum fine $150). Good thing Jeffco didn't close
Dinosaur Ridge too.
Weather:Cloud cover changed around all day with high cirrus above and cumulus
below. At one point the wind on the platform was from the southeast but the
clouds were moving over from the west. Even without birds the sky was
pretty entertaining today. At 12:30 MST the wind on the ridge shifted to
come from the west and with sudden new force at 7 BFT for about an hour.
After that the winds continued from the west gusting up 5-6 BTF rest of
watch. Good cloud cover most of the day. (PWS Idledale)
Raptor Observations:Migrating Raptors: The two Bald Eagles (one adult, the other a 4/5th year)
spent a lot of time circling overhead, within unaided view, gaining
elevation. Same with Osprey and Cooper's, who seemed to appear from below
eye level on the east side of the ridge and circle up at the north end.
Non-Migrating Raptors: Tracked a minimum of three local Red-tailed Hawk
individuals repeatedly during the day. A local Cooper's Hawk cycled up and
down above Matthews-Winters Park. An American Kestrel (male) hover hunted
over the west side of the ridge the entire time I trekked down at end of
watch.
Non-raptor Observations:Also seen or heard: Spotted Towhee (1), Woodhouse's Scrub Jay (1),
Townsend's Solitaire (1), House Finch (1), American White Pelican (2),
Black-billed Magpie (1), Common Raven (4), and White Throated Swift (5).
Predictions:Monday the warm-up continues.

Site Profile] [
Day Summary] [
Month Summary]
Site DescriptionDinosaur 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.
