Visitors:
Big thank you to Karen & Mike Fernandez, Kathy Barnum, and Sammy Korengut for helping me look for birds today. We had ourselves a challenge! Visitors were low at the site today, with only 8 stopping by briefly. Many visitors were seen looking in our direction but moving on. I personally think the sandwich board was helping bring attention our way, as we would see people look in our direction, see the board, and then come say hi.
Weather:
We had another hot day on the ridge but luckily had cloud cover on and off for most of the day. Winds started from the E in the morning, shifting N and then NW by the end of the day. Wind speeds were moderate as the wind shifted. Relative humidity was incredibly low today, seeing some single digit readings throughout the day.
Raptor Observations:
Migration was very eerily quiet today with 13 migrants counted. We saw a nice amount of AK today and some close adult accipiters first thing in the morning. Local RT (3), TV (3), and GE (1), were seen today many times.
Non-raptor Observations:
Despite migration being slow, we did have a very exciting visitor at the ridge early in the morning. Karen Fernandez noticed an odd looking raven with long nasal bristles and white neck feathers that could only be seen when the wind was blowing correctly. Her husband Mike was able to snap some photos of the bird, and will be submitting the photos and report to ebird as a Chihuahuan Raven. This would be the first record of a CHRA in Jefferson County. Other than the CHRA, passerine activity was also low today. We did see a ROWR, many of our FOTS, as well as SPTO (2), TOSO (2), SCJA (1), BCCH (2), CORA (7), and AMCR (4).
Predictions:
Temperatures should be lower tomorrow with more cloud cover. Winds are predicted to be from the W reaching moderate speeds with some high gusts. We can often see E winds prevail despite W winds being predicted, but either way we are just hoping for a good day of migration.

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)
