Visitors:
Thank you to both Kerrie, Patricia, and Chloe for volunteering this morning
and for our lovely afternoon crew of Ellie and Ryan. Today was Ellie’s
last day volunteering with Dinosaur Ridge this season before she goes off
to work with warblers in North Carolina for a few months before heading off
to Alaska! Thank you for all of the hours you put into the ridge this
season!

We had a total of 7 visitors on the ridge today.

Weather:
Today was consistent with 20% cloud cover, winds up to 25 mph, and
temperatures around 8C.

Raptor Observations:
Activity of local and migrating raptors was relatively low today. All
migrant movement happened in the earlier hours of the count, a few
highlights being an eye-level Osprey and a line of 6 Turkey Vultures. Local
raptor highlights included a male AMKE and adult SSHA. They were seen
consistently around the platform today, the SSHA even made a bold pass
right between two of the volunteers!

White-throated Swift 1, Northern Flicker 2, Black-billed Magpie 2, American
Crow 1, Common Raven 2, Black-capped Chickadee 2, Mountain Chickadee 1,

Mixture of rain and snow in the afternoon beginning around 14:00, winds up

More site information at hawkcount.org: https://hawkcount.org/siteinfo.php?rsite=123

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,
American White Pelican, and Dusky Grouse. 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.
