Approximately 6 parties of 1-4 people each made it up to the platform, but
no one seemed to be in a chatty or inquisitive mood. Very few even said
hello, but generally folks came up, took pictures and left without a word.
No cyclists.

The first two hours we had sleet (frozen raindrops) and light rain. Rain
columns pushed from north to south along the foothills. The Rooney Valley
side and eastward did not appear to have the same weather as the Hwy 93
side. There was a little bit of sun lighting up the distant southeast
horizon; nothing but dark skies to the west. The sky cleared in small
patches briefly overhead right about the time our two migrating Red-Taileds
came through after about 45 minutes of no rain. After that, the sky
darkened, the ceiling lowered, waves of dark cumulus clouds moved in
overhead and hung above us and to the west. Sleet and rain restarted at
about 11:15 MST and unfortunately we ended the count after 3-1/4 hrs.

Raptor Observations:
When the rain paused briefly after the first two hours, all the local and
migrating Red-Taileds appeared within a 15 minute window. The first
appeared from behind Green Mountain, circled up, went north, paused and
circled above Table Mountain, then continued north to the limit of our
binocs. The second Red-Tailed also appeared from behind Green Mountain
circled up and north, then did a stoop back south, then a glide south back
up in elevation, then another stoop south; four times it did this
roller-coaster move until he led our eyes to a migrating Red-Tailed coming
up from southeast of the ridge. The local acrobat then alighted on the
telephone pole on the Rooney side above the motocross track.

Non-raptor Observations:
Seen or heard: White-throated Swifts (5), Northern Flickers (2),
Black-billed Magpie (1), Dark-eyed Junco (Gray-headed) (1), Spotted Towhees
(3), Western Meadowlark (1). Reported on eBird. Two Spotted Towhees flew
back and forth close to the ground on the north end of the platform between
junipers, scrounging up berries deep inside while it rained. Two mule deer
stared up at us from midway down the east side of the ridge.

The trail was in excellent condition on the way up and down, but if rain
continues it could be slick for Monday's climbers.

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
