Total observation time: 8 hours

Official Counter: Soren Zappia

Observers: Laura Farnsworth

Visitors:
14 visitors. We had our first DFO field trip of the season visit this
morning! They enjoyed watching both local and migrant raptors on the ridge.
Thank you to Ajit and Liza Antony for leading the trip.

Thank you also to Karolyn Chan for volunteering today.


Weather:
The heat wave continued today with record high temperatures in the mid to
high 80s F. Winds were light, starting from the west in the first hour
before shifting east and southeast for most of the day. Cloud cover was
variable - in the morning the sky was mostly covered in thin cloud cover,
which disappeared during the midday before returning in the late
afternoon.


Raptor Observations:
The raptors were active as soon as the count started. We had a string of
Red-tailed Hawks in the morning, already quite high, and a few American
Kestrels. Throughout the rest of the day, more RTs were seen at a
spectacular height, barely visible against the sparse cloud cover. It was
amazing watching how efficiently these birds could utilize lift today!

An afternoon highlight was our second Turkey Vulture flying right overhead,
then thermal hopping north. Even in the late afternoon, RTs could still be
seen soaring overhead and over the ridges, with one final migrant in the
last hour of the count.

Raven activity seemed higher than usual, and they reached heights that
rivaled the RTs. We saw our first Tree Swallows at the ridge as well, and a
group of 6 American White Pelicans.

Non-raptor Observations:
American White Pelican 6, Northern Flicker 1, Common Raven 9, Tree Swallow
3, American Bushtit 2, Townsend's Solitaire 1, American Robin 1, House
Finch 2, Dark-eyed Junco 1, Dark-eyed Junco (Slate-colored) 1, Spotted
Towhee 1, Western Meadowlark 1

Predictions:
A gradual drop observed in barometric pressure throughout the day today
gives hope for a cold front moving through tonight! Temperatures are
expected to drop to the 50s through mid 60s F, with winds light and
variable. Cloud cover is predicted to be light and vary from mostly sunny
to partly cloudy. Trails remain dry.

Site Description:
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is
the best place in the world to see migrating Ferruginous Hawks. Hawk
watchers may see 17 species of migrating raptors; and it is an excellent
site to see rare dark morph buteos including Broad-winged hawk, Swainson's
hawk, Ferruginous hawk, Rough-legged hawk and Red-tailed Hawk. Other
raptors we see include Golden and Bald Eagles, Northern harrier, Osprey,
Peregrine Falcons, Prairie Falcons, Cooper's and Sharp-shinned Hawks,
American Kestrels, Merlin, and Turkey Vultures. American Goshawk is
uncommon but also counted each season. Non-raptor species include Rock
Wren, Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, and
American White Pelican. Birders of any skill level are always welcome. The
hawk watch at Dinosaur Ridge is staffed by Hawk Counter(s) and volunteers
from March through early May.

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 hawk watch signs
from the southwest end of the parking lot to the hawk watch 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, and walk to the flat area at the crest of the ridge.
(Distance: 0.56 miles, Elevation gain: 259 feet)
