Visitors:
It was a busy busy day up on the tower, with the ideal conditions for hawk
migration making it an unofficial launch for this weekend's HawkFest!
Thanks to our qualified observers Chuck, Jaron, Hugh, Liz, Kitty, Chad,
Chip, Noel, Juliette, Patrick, Ian, Karen, Cameron, Olga, Aldo, Larry, and
Robin. In particular, an immense thank you to Jaron and Hugh who bravely
stepped up as scribes for most of the day, Olga who spotted an unbelievable
number of birds, and Chad, who most likely needs an ice pack for his
clicker finger!
We had so many visitors through the day and so many hawks it was impossible
to catch everyone's name, but it was so wonderful to see Stephanie,
Richard, Elizabeth, Julie, Bob, Heather, Cecile, Donald, Scott, Tim, Sue,
Jalen, April and all our other guests who made it such an incredible day up
on the tower!
Commiserations must be extended to all our great volunteers who couldn't
make it today due to work and other commitments - we have put in a special
request for the hawks to time their migration to the weekends in future.
Weather:
Northerly wind, beginning strong, weakening through midday, then returning
in the mid-afternoon. Mainly clear skies, with cloud cover increasing in
the late afternoon. Temperatures in the mid-twenties.
Raptor Observations:
Wow. Going to bed last night, I was prepared for a big day, maybe 20,000
Broad-winged Hawks? The conditions looked good, and yesterday afternoon's
movement had been promising. But nothing could have prepared any of us for
what happened!!
We had our highest counts of the season to date for seven of our raptor
species, totalling over 60,000 individuals. We equalled the highest ever
single day count for Merlin at Holiday Beach with 16 individuals, the sixth
equal best single day count for Bald Eagles with 33, and had our third
highest single day count for Broad-winged Hawks, with a sensational 59,957
individuals. Other significant movers were Sharp-shinned Hawks (495),
American Kestrel (180), Turkey Vulture (102) and Red-tailed Hawk (68). We
also had two pale/leucistic and one western morph Red-tailed Hawks.
The immense passage is caused by a perfect suite of weather conditions,
with clear skies and strong northerly winds in northern Ontario drawing
raptors south, before two days of prevailing bad weather coming from the
south-west across Michigan and along the northern shore of Lake Erie
prevented them from continuing on. This meant that when the barometric
pressure finally lifted overnight and consequently the skies cleared around
southern Ontario and the Detroit River, there were tens of thousands of
hawks queued up ready to take their chance to make the crossing.
The day started fairly slowly with just five birds in the first hour, but
by 0900 EST the Broad-wings were already passing in moderate kettles.
Numbers slowed in the late morning, before picking up into the multiple
thousands through the afternoon. There were seven kettles in excess of 2000
individuals, with the largest single movement of Broad-winged Hawks
involving 3730 individual birds. Between 1400 and 1500 EST, 19,190
Broad-winged Hawks passed through in a single hour.
On a personal note, it was particularly emotional when our local Osprey
chick, who has spent the last few weeks entertaining us by fishing in the
trout pond near the tower and desperately trying to defend his catch from
pesky Bald Eagles, took off from his perch and kept flying higher and
higher - I wish him all the best for his voyage ahead!
Non-raptor Observations:
The eBird checklist for the day can be viewed at
https://ebird.org/checklist/S394064168.
It wasn't just a good hawk day! In the early morning, we were entertained
by a mixed flock of fifteen species of warblers, including a notable nine
Bay-breasted. On the marsh, we had eight American White Pelicans, two
Sandhill Crane and year-highs of Green-winged Teal (120) and American
Wigeon (61). There was a notable southward movement of passerines and
Chimney Swift.
The most astonishing bird of the day was certainly a White-winged Dove seen
flying west in the early morning. This is a new bird for Holiday Beach.
Full credit belongs to Cameron who managed to capture a photo of the bird
as it streamed by!
As a bonus mention, it was a great rodent day with two Musk Rat and one
American Beaver - our first for the season! Monarchs were also making the
most of the good conditions, with seventy seen.
Predictions:
Tomorrow will be a really exciting day at Holiday Beach as the official
opening of the annual HawkFest, with food and merchandise for sale and
plenty of amazing activities and talks through the day. Bird wise, it is
possible that the continued northerly winds through the evening will bring
a small fall of warblers and the overcast conditions should be perfect for
keeping them active around the tower through the morning. Hawk-wise the
easterly winds will continue to push birds along the Ontario Peninsula, and
we will expect small flurries of activity in-between the wet fronts.
