Official Counter: Julie Brown, Phil Brown

Observers: Ann Calder, Annamarie Saenger, Chuck Carlson, Dan Calder,
Dot Currier, Julie Brown, Meade Cadot, Phil McCabe,
Tom Delaney, Tom Momeyer

Visitors:
43.


Weather:
Socked in by morning cloud cover with clearing in the afternoon to variable
skies for the remainder of the day. Winds retained a westerly component all
day and were light but persistent. Temps 55-64F.

Raptor Observations:
Raptors turned on as soon as the sun emerged around 1 pm, with a steady
push of broad-wings in small 'squadrons' of up to 14, small kettles with a
few sharpies and eagles mixing in, and two harriers to bookend the
three-hour push. A fraction of the past days' counts, the afternoon hours
were a welcome change from the first five hours, in which only two migrants
were noted.

Non-raptor Observations:
Ravens (14), resident turkey vultures, and local red-tailed hawks mixed in
with migrant raptors.
Barred Owl called late in the day; Blue-headed Vireo, Pine Warbler, Canada
Goose (4) and other expected local and migrant birds.
Ruby-throated Hummingbirds: 4/46; Monarchs: 14/160

Predictions:
Winds shift east and south, which may shut down migration for all but a few
eager ospreys and peregrines. Watch for a chance of late day showers.
