Observers:

Visitors:
7 visitors. A few bikers and hikers were present today and were curious
about what we were seeing, especially when the birds weren't visible to the
unaided eye!

Thank you to Janet Peters, Jerry Arni, and Kathi Moses for volunteering
today.


Weather:
It was another hot day at the ridge, with record heat in the high 80s F.
Winds started as moderate from the NW but died down in a few hours before
shifting to a very slight E wind by the end of the count. Cloud cover was
variable - the first and last hours were mostly cloudy, but there were few
clouds in the midday.

Raptor Observations:
It was a quieter morning with less local and migrant raptor activity than
the previous few days. Two Cooper's Hawks and a distant American Kestrel
were counted in the first few hours. Later, a migrant juvenile Red-tailed
Hawk was chased off by two local adults. In the final few hours of the
count, we saw RTs and AKs stream past quite high overhead. AKs were our
most numerous migrant raptors of the day with a total of 9.

We had our first good flight of White-throated Swifts in the morning. A
large Bullsnake and a few lizards were also active on the ridge.

Non-raptor Observations:
White-throated Swift 42, Black-billed Magpie 1, Common Raven 4,
Black-capped Chickadee 2, Tree Swallow 2, American Bushtit 3, Mountain
Bluebird 7, House Finch 2, Pine Siskin 1, Spotted Towhee 2, Western
Meadowlark 1

Predictions:
Tomorrow, expect more high temperatures and mostly sunny skies with
moderate winds shifting from W to N as the day goes on. There is a slight
chance of showers after 3 PM.

A visitor informed us that they had spotted a young rattlesnake on the
trail a day or two ago - make sure to look out for them when hiking to or
from the hawkwatch!

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.
