Visitors:
Thank you to all of the volunteers that came out today to help spot migrants! We saw a total of 29 visitors on the ridge today, most of them in the morning before temperatures dropped.

Weather:
This morning started out very pleasant with minimal cloud cover and some nice spring sun. As the day went on the clouds rolled in, bringing lower temperatures and some decent wind gusts. Winds started from the SE today, shifting N as the storm front came in.

Raptor Observations:
Migration was minimal in the morning but the afternoon brought a few brave birds. Most migrants were flying significantly higher than any of the local birds. Some migrants were escorted by locals, some seemed to pass right by them. Local raptor activity was very high again today with 2 pairs of RT seen throughout the day, as well as what one would describe as an intermediate-morph RT. At least 2 local GE were also seen today, sometimes at great heights.

Non-raptor Observations:
Passerine activity was low today with the lowered temps and pressure. Even the Common Ravens were nowhere to be found for periods of the day. AMRO, BCCH, BUSH, DEJU, WOSJ, BBMA, and AMCR were seen today as well.

Predictions:
Snow and high winds are predicted overnight along the front range. We are not expecting much snow tomorrow so we are hopeful for a full day of counting. Bring gloves and shoes you don't mind getting wet as the trail will definitely be snowy and/or muddy.

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. (Distance: 0.56 miles, Elevation gain:
259 feet)
