Observers:

Visitors:
3 visitors. Although visitors were few in numbers today, we enjoyed
spending time watching the birds with them.

Thank you also to Derek Freed and Chip Dawes for volunteering today! Today
was truly a team effort with the distant high birds.


Weather:
It was a hot and sunny day. Temperatures quickly rose to the low 80s F
where it remained for the rest of the day. In the morning, clouds were few
but by the late afternoon there was a thin wispy cloud layer in addition to
scattered denser clouds.

After a brief hour or so of light west wind, winds were light to moderate
from the southeast, at their most intense during midday and early
afternoon. During the final hour of the count, wind occasionally gusted
from the west before switching back to east.

Raptor Observations:
Raptors definitely took advantage of the sun and warm temperatures today,
and even local birds were high up within less than an hour of the count
start.

Most Broad-winged Hawks today were seen in the first full hour of the count
quite distantly, but we had one later glide overhead relatively close
midday as well. Sharp-shinned Hawks made up the majority of the
accipitrines we saw today, moving throughout the day. A few Swainson's
Hawks, including a dark morph, were seen in the afternoon. Unlike prior
days, only a few migrating American Kestrels were seen towards the end of
the count.

Outside of raptors, we had two small groups of Franklin's gulls overhead -
one group so close that you could see their pinkish tinge!

Non-raptor Observations:
Canada Goose 2, White-throated Swift 3, Broad-tailed Hummingbird 3,
Mourning Dove 3, Franklin's Gull 40, Double-crested Cormorant 1, American
White Pelican 4, Say's Phoebe 1, Blue Jay 2, Woodhouse's Scrub Jay 1,
Black-billed Magpie 1, American Crow 2, Common Raven 2, Black-capped
Chickadee 1, Tree Swallow 3, Violet-green Swallow 1, swalow sp. 1, American
Bushtit 3, Rock Wren 1, Blue-grey Gnatcatcher 1, Red-breasted Nuthatch 1,
House Finch 3, American Goldfinch 1, Spotted Towhee 1, Western Meadowlark
1, Red-winged Blackbird 2

Predictions:
Tomorrow, we expect similar high temperatures and sun. Winds from the
southwest are predicted, light to moderate in the morning but stronger in
the afternoon, with possible wind gusts of 30+ MPH. Make sure to bring lots
of water and sunscreen!

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.
