Visitors:
5 visitors. We had a few visitors in the morning to see the birds, and all
enjoyed all the kestrels zooming right past our heads!

Thank you to Helen Berkman, Ric Olson, Ryan Gannon, and Chris and Cayce
Gulbransen for volunteering! We especially appreciated your flexibility
with weather today.


Weather:
It started as a cloudy and cool day in the morning with light SE winds and
temps in the mid 60s F. Cloud cover started mostly cloudy but increased to
overcast as the morning progressed.

Around 11:45 MST, lightning was detected in the area, and the count was
paused for safety per our protocols.

At 1:00 MST the count resumed, and we had about 40 minutes before multiple
lightning strikes were detected only a few miles away and it started to
rain. As radar indicated storms would continue, the count was ended at
13:39 MST.

Raptor Observations:
Despite the shortened count day, we had a good flight in the morning,
including accipitrines, Red-tailed Hawks, and American Kestrels. While most
migrants were to the west, many of the AKs were low past the ridge.

A highlight of the day was seeing four migrating Osprey in the morning,
with two in the first hour. We also had our first migrant Swainson's Hawk,
a light morph adult. After yesterday's local bird, we were excited to count
one!

The only migrant after the count resumed was a distant Cooper's Hawk to the
west, speeding past just as the storms closed in.

Today we counted our 1000th migrant of the season, a Sharp-shinned Hawk!

Non-raptor Observations:
White-throated Swift 25, Broad-tailed Hummingbird 1, Hairy Woodpecker 1,
American Crow 1, Common Raven 3, Black-capped Chickadee 1, swalow sp. 3,
American Bushtit 2, White-breasted Nuthatch 1, House Finch 2, Pine Siskin
1, Spotted Towhee 1, Western Meadowlark 1

Predictions:
Tomorrow, expect clouds and cooler temperatures in the low 50s to low 60s
F. Light NE winds are predicted.

There is a chance we have more storms in the late afternoon. Keep an eye on
the radar and stay off the ridge if there is lightning nearby.

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, and
American White Pelican. 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.
