Visitors:
Johannes, Michelle and Dee were treated to a very good day at the watch.
Many thanks to them for helping us.
Weather:
Very good conditions for migration today. Fairly mild winds for the first
time in two days and a risen barometer said "Come on down!" to migrating
raptors. The sky was filled, or not, with unusual transitional cloud
formations as if confused by the sudden change to high pressure. NW winds
were strong enough to encourage the birds but not force them too far away.
Raptor Observations:
The skies were filled today. 2023 turkey vultures made their erratic
journeys by the site today. The buteos responded to the perfect conditions
with 173 red-tailed hawks and 55 red-shoulders. Sharp-shins were a little
hard to find today but 44 were counted, Cooper's hawks numbered 9 and for
once (finally!!) we hit the accipiter hat trick with our first northern
goshawk. Falcons were a little scarce but another hat trick with 3
kestrels, 2 peregrines and 1 merlin. 5 harriers rowed by and 3 bald eagles
made the trip.
Non-raptor Observations:
Rusty blackbirds were heard in the trees behind us. One sandhill crane was
noted with his snappy wing beats high in the sky.
Predictions:
The winds, although lighter, will still have a northern flavor to them
tomorrow. Barometer, although starting to tail off towards the end of the
day as another rain system is due Saturday, will still be in the Go Zone.
Should be another good day but the light winds in the first couple of hours
may slow the start.
