Dinosaur Ridge - Denver Field Ornithologists
Golden, Colorado, USA
Visitors:
We had three visitors to the hawk watch today. including regular visitor Ric Olson. Thank you to Kathie Moses, Karrie Lagon, and Cayce and Chris Gulbransen for volunteering at the ridge today!
Weather:
Temperatures continue to stay mild with high cloud cover and precipitation. Winds were from the E/NE today at low speeds, apart from a few gusts that came through during a precipitation event. A period of cold rain and hail blew through causing us to pause the count for an hour and 15 minutes during the afternoon. We ended up calling the count early due to further precipitation.
Raptor Observations:
Migration continues to push through! Our first migrant of the day came through before 0600 MST during the morning flight count. Broad-winged Hawks began moving in the 0800 hour and continued throughout the day with the last one coming in the last hour. Osprey have had a great presence lately with birds coming directly overhead as well as over the W ridge. Most of our migrants came W of us today, which is typical in an E wind. An Osprey was seen on the hike out. Soren monitored the morning flight this morning starting at 0500 MST. Highlights included Brown-headed Cowbirds, Brewer's Blackbirds, Yellow-rumped Warbers, Northern Rough-winged Swallow, and Cliff Swallow. We are hoping to get a few more morning flight counts in before the end of the season.

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:
