Official Counter: Joyce Commercon

Observers: Robert Hill

Visitors:
Robert Hill and grandson Cameron, plus two more family members and their
dog, arrived early to check out the HawkWatch; Robert and Gunner (the
well-behaved, leashed, family dog) stayed to help spot for a few hours
while the other family members enjoyed a hike along the Ridge. Later in the
watch as more hikers stopped by, there were a few who inquired about the
watch and what we were seeing. Everyone practiced social distancing on the
platform, but 6-ft social distancing was sometimes hard to maintain on the
trails.
Jefferson county (and my home county, Douglas) have instituted a
stay-at-home order due to the coronavirus, effective Thursday, March 26 at
8am MDT. Going out for exercise may still be allowed (check to be sure) but
a regular HawkWatch will likely not be conducted until this order is
lifted.


Weather:
The day started out partly-cloudy with a lot of thin diaphanous clouds
allowing for both sunny warmth and good hawk-watching. Cloud-cover
increased from 30- to 90-percent with a mix of thicker white, thinner
cirrus type and translucent clouds. Winds came mostly from the east (bft
2-3) but became variable near noon MST shifting finally to come from the
west at bft 3-4 by 12:30pm. Cloud-cover began to shift considerably during
this time, with thin clouds at one point resembling a huge, ragged
checkerboard, which eventually disappeared, sheared apart. The temperature
increased from 12 C to 16.5 C. Visibility was good.

Raptor Observations:
All the migrants passed by from about 9am to 10:30am MST and were evenly
split with about half moving along the far western ridges and the other
half migrating reasonably close to Dinosaur Ridge. An adult Cooper’s Hawk
was kind enough to pass "easily visible" to the naked eye on its way north.
It was also pleasant to watch a juvenile Bald Eagle, first spotted by
Robert, make its way steadily north up Rooney Valley. No local Turkey
Vulture was seen today but a local Golden Eagle was spotted north of I70
and again, later, one was seen moving south along the western ridges. For
the last few hours of the watch, it was very quiet; no migrants and hardly
any local raptors were seen even though the thin-clouded sky was ideal for
spotting.

Non-raptor Observations:
Three or four Townsend's Solitaires moved up and down the Ridge near the
platform in the morning, often voicing a sweet, rapid burble. Mountain and
Western Bluebirds were seen in a few small groups heading north along the
Ridge. Also seen or heard today, mostly in the morning, were American
Robin, Black-billed Magpie, Mountain Chickadee, Spotted Towhee, Dark-eyed
Junco, American Crow, Common Raven, and Woodhouse's Scrub-Jay.

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.
