Visitors:
Thank you to Karen & Mike Fernandez and Sammy Korengut for your help spotting migrants today. We saw 22 visitors at the ridge including long time visitor and counter Joe who helped spot for about an hour. We also saw two visitors from Seattle.

Weather:
We had a warm and sunny day with thin cloud cover for most of the day in areas. Clouds brought precipitation south of us by the end of the day, but didn’t reach the ridge. Winds were from the E today at mild speeds.

Raptor Observations:
Migration kicked off shortly after arriving this morning with birds below eye level and just above horizon both east and west of us. We had another good flight of FH today, typically seen earlier in the season. Eagles also continue to move, another early migrant. BW continue to move making our record breaking count even better by the day! We also got to see two kettles of TV, one 9 and one 7, which is always a treat at our site. Migration came to almost a halt in the afternoon with a few RT and TV seen. It wasn’t until the last 30 minutes that we saw our first AK, and the second as we were leaving. Non-migrant activity was high today with TV (4), RT (3), SW (1), GE (2), and BE (2).

Non-raptor Observations:
Non-raptor highlights of the day include a WEKI that perched in the burnt juniper at the site and 2 AMWP that came close. The BGGN could be heard for most of the day, as well as many of the regulars such as SPTO and ROWR.

Predictions:
Cloudy tomorrow with a chance of precipitation. Winds may be variable but shouldn’t be too strong. We could see a decent push again.

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)
