Visitors:
We would like to thank our volunteers Bob Mitchell, Ric Olson, AJ Dotti, and Laura Hollenbaugh for helping us spot birds today! A total of 28 people visited the ridge today, and a handful of really great dogs came with them. Can't make it out to the ridge and still want to follow along? Check out our Trektellen page and follow along with live updates at https://www.trektellen.org/count/view/4515/20250301 .

Weather:
Today was another beautiful spring day in Colorado with cirrus cloud cover and light winds from the SE/E for most of the day. Barometric pressure dropped relatively significantly over the day and dark clouds rolled in the last hour. No precipitation was predicted, but it sure felt like it was on it's way.

Raptor Observations:
Raptor activity was slow in the first hour of the day with very few birds seen at all, minus one migrant and one local. Movement picked up a little bit and brought us some very high flying overhead birds. Our highlight of the day was a dark-morph Ferruginous Hawk that flew much lower than other migrants seen today. Migratory activity continues to be as expected for early March at Dinosaur Ridge. Local raptor activity picked back up today after a few seemingly slow days. 5 species of non-migrating raptors were seen today: RT, GE, BE, AK, and CH. The Cooper's Hawk gave us great looks, and also led us to our migrating BE and a RT.

Non-raptor Observations:
We got our FOS Sandhill Cranes today! 6 birds in a beautiful V-formation came astronomically high through the western valley in the last hour of the day. We have discussed SACR in the last few days, hoping they would come soon. MOBL movement continues to be present throughout the day. We also heard our FOS Spotted Towhee today and look forward to them returning en masse around the ridge. Sandhill Crane 6, Northern Flicker 1, Black-billed Magpie 2, Common Raven 5, Black-capped Chickadee 4, American Bushtit 2, Mountain Bluebird 17, American Robin 4, House Finch 3

Predictions:
Tomorrow is expected to be a bit chillier than it has been the last few days, but still a very pleasant day in early March. Winds are predicted to have a West component to them, potentially bringing a slow count day. Colorado spring is notoriously impossible to predict, though, so we stay hopeful for a great day! Trail conditions are currently ideal.

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)
