Visitors:
19 visitors. We had another DFO trip visit this morning! The group was able
to see raptors at all distances including close a close RT, AK, CH and SS.
Thank you to Jason Bidgood for leading the trip.

We also saw many dogs on the trails today, including one wearing a baseball
cap!

Thank you also to our volunteers Janet Peters, Chris Gulbransen, and Cayce
Gulbransen for all the help and great spotting today!


Weather:
The day quickly warmed and we spent most the day in the low 80s F. Cloud
cover was thin and wispy but extensive in the morning. While the thin
clouds faded, in the later afternoon we had mostly cloudy skies with more
defined denser clouds, at times blocking the sun.

The wind was light, except for a windier period midday. Winds started as
west but switched to east in midafternoon.

Raptor Observations:
Raptor activity slowed a bit today compared to the past few days, but we
had a Sharp-shinned Hawk, and two American Kestrels migrate in the first
hour close overhead, as well as a distant Cooper's Hawk. After that,
activity was quieter with a few birds per hour from late morning to
midafternoon, mostly far on the west side. Highlights included an Osprey
gliding through the sky in the late afternoon, and a Northern Harrier
soaring high to the west in the final hour of the count.

There was a lot of Turkey Vulture activity throughout the day, but none
seemed to want to migrate, often gliding quite far north before turning
around.

Non-raptor Observations:
White-throated Swift 8, Say's Phoebe 1, Steller's Jay 1, Woodhouse's Scrub
Jay 1, Magpie 1, American Crow 2, Common Raven 5, Black-capped Chickadee 1,
House Finch 1, Pine Siskin 1, Spotted Towhee 1

Predictions:
Tomorrow, similar high temperatures are predicted with highs near 80F.
Cloud cover is predicted to vary from partly cloudy to mostly sunny.

West winds are predicted, starting as light in the morning intensifying in
the afternoon, with possible wind gusts of up to 29 MPH forecasted.

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)
