Visitors:
We had another busy day on the count site with up to 6 observers at the site at any given time, so thank you to all that helped spot high birds today! We saw 49 visitors at the ridge today. A hotspot was seen by a hiker just south of our count site and was put out very quickly by Jefferson County efforts.
Weather:
Today was a sunny and warm day with high temperatures and mild winds. Winds shifted throughout the day but we did see a nice E wind for the first part of the day. Cloud cover decreased as the day went on, leaving us with almost empty skies as we ended the day.
Raptor Observations:
We saw another strong migration for the first few hours of the day with the afternoon slowing down a little bit with the wind shifts. Birds started out taking a western line and then began coming high overhead, making spotting them challenging. Highlights include our first SW of the season and a dark-morph FH that both came lower than most of the other migrants. We continue to see strong AK and accipiter flights. Non-migrant activity was high today with multiple RT (3), GE (2), and TV (up to 4 at a time) seen many times throughout the day. We also watched a SS dive below the ridge.
Non-raptor Observations:
Non-raptor highlights include two AWPE, the season’s first WEME, and continuing MOBL (12). Other non-raptors include WTSW (50+), NOFL (1), TOSO (3), AMRO (2), SPTO (1), BCCH (2), HOFI (4), CORA (7), and AMCR (3).
Predictions:
Tomorrow should be another good day for migration with sun all day and winds from the E. Birds may be high but they will hopefully be moving.

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. Northern 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 a
Hawk Counter and volunteers from 9:30 AM to 5:30 PM from March 1st to May 14th,
weather permitting.
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)
