Observation start time: 07:30:00

Total observation time: 5.5 hours

Official Counter:        Chris Burris, Tom Bolohan

Observers:        Chris Burris, Dave Brown, Matt Oswald, Tom Bolohan

Visitors:
A couple of visitors today ... Matt and Jessica who were great observers
and helped with today's spotting of raptors and thanks to Matt O, Chris B
and Tom B for doing today's count with me.

Weather:
Temps ranged from 13C to 21C. The wind was moderate and mostly N to start,
switching to NW, about 15 km/h with occasional gusts. Cloud coverage was
extremely variable, but with lots of sun patches and texture as the day
progressed.

Raptor Observations:
One of the best hawk watching days I've seen in the past few years with
near perfect conditions weather wise resulting in a very good flight today
with 4,436 raptors tallied.

The bulk of today's raptors were Broad-winged Hawks (4,263) and involved
lots of kettles right above or just north of the hawk watch area.  Several
kettles formed with between 100 - 200 Broadwings in them (sometimes with a
few other species joining them) and at least 3 kettles exceeded 500 BWs.
We were able to do a reasonably accurate count today as the flight height
and great backdrop of clouds made them quite visible especially as they
streamed out of each kettle to the west.

There was also a decent number of N. Harriers today (25) along with Am.
Kestrels (65), Ospreys (12), Bald Eagles (21 - almost all immatures that
were tallied with only a couple of adults that were counted as they were
way up with the BWs and streaming hard to the west) and a few Merlins (6).

Non-raptor Observations:
Non-raptors included: Canada Goose, Ring-billed Gull, Herring Gull,
American Crow, Blue Jay, American Goldfinch, European Starling, Cedar
Waxwing, Mourning Dove, Song Sparrow, Ruby-throated Hummingbird, Indigo
Bunting, Rock Pigeon, Barn Swallow, Red-bellied Woodpecker, House Wren,
Common Yellowthroat, Northern Cardinal, Cliff Swallow, Rose-breasted
Grosbeak, Eastern Wood-Pewee, Blue-gray Gnatcatcher, Warbling Vireo,
Northern Flicker, Hairy Woodpecker, Pileated Woodpecker,  American Robin,
Gray Catbird, Yellow-bellied Sapsucker, Least Flycatcher, Great Crested
Flycatcher, Red-breasted Nuthatch, Red-eyed Vireo, Black-capped Chickadee,
Great Blue Heron, Belted Kingfisher, Yellow-rumped Warbler, Tennessee
Warbler, Palm Warbler, Purple Finch, and Semipalmated Plover.

Predictions:
Fairly strong SW winds are predicted for Saturday which may bring some
birds right along the cliff edge (Osprey, Bald Eagles, N. Harriers and any
of the falcon species).
