Visitors:
We had 44 visitors to the ridge today including a nice person named Hampton who might join Denver Field Ornithologists.
Weather:
A very sunny day with a light gusty wind that changed directions some, but was mostly from the Southeast. Around 2 MST we had high thin clouds that were a great background.
Raptor Observations:
Our migrants started low until about 11 am MST. After that all of our migrants were really high. It is quite possible that we missed a lot of migrants because they were simply too high to be seen. Our unknown raptor was flying near a kestrel. This bird was bigger than a kestrel and looked falcon-ish, but it was too far away to rule out Cooper's Hawk. I would guess a prairie falcon, but there is no way to know. In addition to our usual cast of local red-tailed hawks we had two local Cooper's hawks and a local Golden Eagle.
Non-raptor Observations:
We had a leaf migrate overhead with a Height of Flight of 4. We also had 6 American White Pelicans and a few Double-crested Cormorants. Towards the end of the day we had two sandhill cranes flying super high in the air. We also had a lot of baby ballooning spiders today. Some little spiders shoot a web in the air and they go where the wind takes it.
Predictions:
Another hot day that is mostly sunny and will have high winds. An over 15 mph wind will be a nice tail wind for our migrants. I expect tomorrow to be similar to today with the migrants very high, except now they should be passing us faster.

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)
