A birding couple from the Dakota's, Ray and Chris, visited for an hour or
two in the morning. They were very interested in the program and birds and
were helpful spotters. They said they might return on Saturday.

The first day of the Hawk Watch 2018 season was pleasantly mild for early
March. There were light winds from eastern directions and temperatures
rising from the low 40's in the morning to the upper 40's in the afternoon,
with a virtually cloudless day. (Weather data including humidity from
Lookout Mountain Weather Underground station)

Raptor Observations:
There was a small flurry of both local and migrating Red-tailed activity
mid to late morning. Three migrating Red-tailed were tallied during this
time and local birds were somewhat common to the south and west. There was
only sparse raptor activity for the remainder of the day. In the early
afternoon an immature Golden Eagle spiraled slowly from the south to north
gaining elevation. It was lost in the southern sun and could not be seen
passing any further north, so as a judgement call was not counted as
migrating, though it may well have been.

Non-raptor Observations:
Also seen or heard were Black-billed Magpie, Townsend's Solitaire, and
Common Raven.

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
