Visitors:
We welcome visitors to our site and are very willing to share migration
information, photography and ID tips with them. We have cards and
pamphlets, so come and talk to us. However, during times of high traffic,
requiring extra focus and concentration, we would respectfully ask that
everyone use their indoor voices and allow us to fulfill our mission to the
best of our abilities. Thank you.
Weather:
Another day of change, as heavy rain fell before the start of the watch and
frequent revisions of the cloud structures kept the comfort level changing.
It was a very warm day in the end, with temperatures reaching the
seventy-six degree mark. Winds were mostly SSW, but ventured up to fifteen
mph from WSW, before receding in the final hours. Cloud cover varied, but
the most prevalent conditions allowed plenty of sunlight in the afternoon
hours, enhancing the heat. The thermal haze was not in the north today, but
the wind turbines in Canada had an eerie look to them.
Raptor Observations:
The flight lines were not hidden by haze today, as we had feared. It was
mostly sharpies to start the day, but eventually, turkey vultures appeared
and actually flew more or less directly over us, a pleasant surprise. This
still being October, turkey vulture month, they lead the way with 854
floating by. It took them some time to get moving and it never seemed to be
heavy traffic, but like your grocery bill that adds up when you buy small
items, at the end of the day you have a fairly decent sized number.
Sharp-shins began the count, flying sine wave patterns as they tried to
dodge the worst of the wind, but they were a little hard to find in the
final hours. We managed to locate sixty-four of them. We had a run of
red-tailed hawks in the afternoon, but it was short-lived and we ended with
twenty-one on the day. Three kestrels made it through. Two peregrine
falcons were noted, the second was not seen until the first one made a dive
at it. One Cooperâs hawk went through with the vultures. Also tagging
along was a light-morph rough-legged hawk. This morph has been camera shy
this year, only the dark-morph gave us good looks a few days ago.
Non-raptor Observations:
The high winds kept most of the birds away from our area again. Only a few
blue jays were seen and even fewer crows were noted. Plenty of starlings
rushed through in moderate sized groups in the morning hours. Our local
ducks stayed put for the most part with few of them taking to the air. One
lonely monarch was seen. Another day of all quiet on the windy front.
Predictions:
The temperatures will drop about twenty degrees tomorrow and even more in
the following days. The winds turn to the west overnight and then more
northerly as the day progresses. They will be perhaps a little stronger
than we might prefer, but better than southerly winds, to be sure. The
barometer will rapidly rise about three tenths of an inch, peaking at
midday before falling again, as Sunday may bring showers. Skies should be
partly cloudy. This appears to be the best day of a mixed lot but with a
lot of change on the menu, the forecast may vary from day to day. The winds
should be more favorable over the next few days but the rain showers may
interfere and confuse matters.
