Visitors:
We welcome visitors to our site as we are eager to share the joys of hawk
watching with one and all. Although there may be times in which we are all
very busy and need alone-time to concentrate, those are the times that are
most enjoyable for visitors as the skies are filled with migrating raptors.


Weather:
Another day of winds that seemed to exile all the birds to Elba, at least
for the first three hours. The winds were slow out of the blocks and
vacillated around the southern quarter for most of the day. Peaking around
eight mph at 1100, a little easing was noticed in the late afternoon when
there seemed to be perhaps slightly more of an eastern element. 
Temperatures reached the seventy-three mark and it was comfortable with
very low humidity. The sky stayed clear, for the most part, with high
cirrus clouds slowly developing a light veil over us, a good portion of
that may have been airplane contrails spreading out over time. The
barometer was dropping, although staying well above thirty inches. Birds
were late to arrive, and seeing broadwings later in the day was a little
surprising. Their flight line was a bit of a mystery as they popped up to
the north of us with no advance warning. 

Raptor Observations:
At first, it seemed that our high-count day for the season, was going to be
followed by our low count day. The morning hours had zero birds and we had
resigned ourselves to a wasted day until the first afternoon hour.
Broadwings made a late run in the last hour to snatch victory from the jaws
etc. etc. with fifteen total. Sharp-shinned hawks are still waiting in
their staging area for the most part, but their numbers should start to
increase fairly soon. We counted six today. Their usual traveling
companions at this time of year, the kestrels, put four on the board. Only
one harrier was noted. The larger birds were powering through today, with
two each of the bald eagle and osprey species being counted. Young
peregrines also seemed to be on the move with three counted. 

Non-raptor Observations:
Pelicans seem to be moving closer to us with some of them roosting by the
jetty near Celeron Island. Flights of various sizes made appearances in the
morning hours. The small group of common terns passed through again. They
do not appear to be interested in feeding in our area though. A red-bellied
woodpecker was noted across the slip on a bare branch which has held a
flicker, a cedar waxwing, and other birds from time to time. There has been
a pair of great egrets that seem to be holding a grudge against each other.
Today they blew off some steam in a little ado. (NYT’s crossword word for
fight) I think Mark may have some pictures on our Detroit River Hawk Watch
Facebook page tonight. The swallows were on the periphery today, fairly
distant, as were the gulls for some reason. The monarch count was the
opposite of the bird count with most of them in the morning, and very few
in the afternoon. Thirty-six were counted.

Predictions:
Tomorrow’s weather will be very similar to todays, but with more clouds.
The barometer will be lower, but still above 30.1 inches. Temperatures will
be a couple of degrees higher in the seventy-five-degree range. Winds will
switch to the southwest in the morning hours and climb, but peak lower than
they did today, at six mph. That is a fairly mild wind so perhaps we will
see more birds tomorrow. As forecast currently, Thursday may be better with
moderate northerly winds predicted. We are getting into the time frame
where we might start to see larger congregations of broadwings, although,
historically, it is still early.
