Visitors:
We surprisingly had one visitor to the ridge today. This lady was running and stopped to wave before continuing her run. On a day with freezing rain/ snow making icicles form on my hat, she counts as a visitor.

Weather:
Today was a delayed start because of the low clouds and rain/snow. While I was up there the clouds cleared slightly, but the snow was ever persistent. I stayed up there for about 2 hours before heading down, due to being swallowed by the clouds. We waited nearby for a couple of hours, but the end of the precipitation kept getting pushed back. We finally decided to end the count as the weather kept getting pushed back, and migrants probably won't be leaving today.

Raptor Observations:
I only saw two raptors all day today, and both were on my drive home. There was a Red-tailed Hawk in a tree, and a Swainson's Hawk on a wire, both of which were puffed up and did not look like they were going anywhere anytime soon.

Non-raptor Observations:
There was a brief 15-minute period without snow, and in that period I saw a Say's Phoebe, 2 Dark-eyed Juncos, and a Northern Flicker. Flying through the clouds was a Common Raven. I never saw it, but I heard it calling in a very ominous way.

Predictions:
Tomorrow looks like a partly cloudy day that turns into a rainy/snowy day. Around 2 MST (3 MDT) it should start raining before turning to snow. I plan on being up there in the morning and we will see how the weather changes throughout the day.

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 a
Hawk Counter and volunteers from 10:00 AM to 6:00 PM from March 1st to May 10th,
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)
