Visitors:
Thank you to Karen & Mike Fernandez, Sammy Korengut, Kathy Barnum, and Natalie Uschner-Arroyo for sticking out the snowy conditions and helping count todays migration. We had 16 visitors at the ridge today including a visitor from DC and a gentleman who visited while hiking a few times last season.
Weather:
What started out as a nice sunny morning was slowly filled in by scattered snowstorms for the rest of the day. Snow could be seen west of us all day, as well as north and south of us for bits of the day. Visibility was surprisingly only limited for under an hour total. Temperatures were low but manageable, and winds were from the NE for a good chunk of the day while we could see storms moving in from the SW, eventually giving way to the SW winds.
Raptor Observations:
Despite the snow, birds were still moving today. Our first migrant of the day was an adult dark Harlan’s RT that moved through the west valley and found an updraft just south of the platform. Other highlights included a gorgeous Grey Ghost coming directly overhead in the last 10 minutes of the day and an adult PG that came just below eye level along the east side of the ridge following a dark-morph RT. Migrants were seen below eye level both east and west of the ridge, or overhead within the limit of an unaided eye, giving us great looks. Non-migrant activity was also very high today with a dark-morph RT seen flying directly south twice today, a BE flying south just below eye level along the ridge, one local GE displaying near Mt Morrison, and the local RT pair seen throughout the day hunting and interacting with each other.
Non-raptor Observations:
We had a couple surprise non-raptor guests today including two GBHE flying north just above Green Mountain, and a lone CANG again heading north through the western valley. Other non-raptors today include HOFI (3), DEJU (2), BCCH (1), AMRO (7), TOSO (5), SCJA (1), CORA (13), and AMCR (11).
Predictions:
Tomorrows weather prediction shows mostly cloudy skies and mild spring temperatures. Winds are predicted to be out of the E in the morning with the potential to shift W in the afternoon, but overall mild speeds. We are hoping for a nice push of migrants that did not move during todays snow.

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)
