Visitors:
We had 17 Visitors to the ridge today two of whom were from the UK.

Weather:
Today started as a warm, sunny day, and turned to a super windy, cloudy sky. Rain was all around us by the end of the day, especially to the southeast and distant west.

Raptor Observations:
Our migrants were high over the horizon until the wind picked up and all of the migrants dropped lower. Only 8 Kestrels were seen before the wind dropped them. Everything seemed to struggle to get up the strong northern wind except the peregrine falcon who effortlessly glided past us. An immature red-tailed that migrated had dove a few times at a peregrine that was also migrating. Some of our migrants are starting to be missing feathers on their journey, especially juvenile birds getting their adult plumage. In local news we had plenty of local Red-tails, one being an immature, a local Peregrine Falcon, that was diving at a raven on its way south, a Bald Eagle, a Ferruginous Hawk, a Swainson's Hawk, and a Sharpshin who wasn't local on purpose as the wind prevented this bird from flying north.

Non-raptor Observations:
We had a Common Raven that was flying around with bread in its mouth. It could have been a rock, but we think it was bread. We had a flock of 10 Franklin's Gulls fly North but later had 40 more gulls fly southwest in the strong headwinds. Uncommon to the ridge/ other birds seen were, Yellow-rumped Warblers, Blue-gray Gnatcatchers, Cliff Swallow, Orange Crowned Warbler, Double-crested Cormorants, Mallards, and Broad-tailed Hummingbird. There were lots of swallows and swifts passing through during the stronger winds.

Predictions:
Tomorrow looks to be a sunny day that gets cloudier as the day goes on. The wind appears to be fairly steady in an overall eastern direction.

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)
