Total observation time: 7 hours
Official Counter: Mary Carnahan
Observers: Don Taylor, Ernie Gribble, Jim Dunn, Keith Sealy,

Visitors:
Visitors today were Marty and Edith from Kitchener; Mike and Anne from
Winnipeg.
Weather:
We had beautiful weather today for hawk watching, with comfortable
temperatures ranging from 16 in the early hours to 24 by the end of the
watch, with humidity dropping throughout the day from 77 % in the first
hour to less than 50% by the end. Very comfortable for humans and
apparently for birds as well. The wind was strong from the ENE to start
and swung around to the ESE for the afternoon, but had gone south by the
very end.
Raptor Observations:
The raptors seemed to agree that it was great weather for migrating,
resulting our total of 336 raptors from 7 (seven!) species including Osprey
(6), Bald Eagle (6), Northern Harrier (17), Sharp-shinned Hawk (155),
Coopers Hawk (4), Broad-winged Hawk (6), and American Kestrel (140).
There was also a lot of activity from Bald Eagles that we decided were
locals, mainly because they were flying at the cliff, often flying quite
low, despite the easterly component to the winds which made everything else
fly really high. As well, we had a number of Bald Eagles fly eastward
along the cliff, which is the usual pattern for the locals fly east, fly
west, and back, and forth, and so on. Those that were counted were flying
high at the north end of the field.
Towards the second last hour of the day, a few Kestrels started hunting as
they went west, making it difficult to keep tabs on them. For several
minutes one or two, or even three, Kestrels would stop in mid-flight and
begin hovering over the field in front of us, diving, and then hovering
again. It was entertaining to watch, but at least one observer really had
to keep tabs on these birds, making sure that eventually they all exited
westward. And eventually, they did.
Many thanks to Don, Ernie, Keith, Steve, Mark, Ronnie and Mary for their
assistance in keeping tabs.
Non-raptor Observations:
Non-raptor highlights included 4 Great Egrets seen from the observation
knoll, a New Species for this season and what a lovely sight! The first
one flew east across the field, then veered north and went down in the
woods across from the knoll, where we know there is at least one pond. The
other three came together, flying eastward along the cliff, then veered out
over the lake to the south. None of the egrets appeared to be tagged.
About halfway through the watch, a Kingfisher that we had heard calling
from below the cliff appeared to the south. It flew low right across the
observation knoll giving everybody great views. Also seen from the
observation knoll were a few Barn Swallows and numerous Tree Swallows,
mainly during the morning hours. Other highlights today included a couple
of Swainsons Thrushes, Caspian Tern, flocks of Goldfinches, and 10 Warbler
species which were Magnolia, Black-throated Blue, Chestnut-sided,
Black-throated Green, Black and White, Bay-breasted, American Redstart,
Ovenbird, Wilsons and Common Yellowthroat.
Butterflies today were Monarch, Viceroy, Black Swallowtail, Cabbage White,
Orange and Clouded Sulphur and Eastern Tailed Blue.
Predictions:
Northerly winds are expected for Friday though they are now predicting rain
for a goo dpart of the day. Still any birds in the pipeline may make a run
for it ahead of this big low pressure system that is supposed to cross the
Great Lakes region Friday and Friday night.
NOTE...The forecast for the weekend has also changed just in the past few
hours and they're now calling for NORTHERLY winds both Saturday and Sunday
with only a small chance of rain. These northerly winds are setting up from
a line just south of the James Bay area all the way down to the lower
lakes. It's possible this will bring the first good push of Broadwings...so
let's hope the forecast holds.
