Monarch Fall Roost

Date: 09/09/2010

Number: 10000

News just received from Presqu'ile Provincial Park a little before 5 pm on Thursday, September 9th:

"The best display of Monarchs I've ever seen is going on in the park right now. There are hundreds--if not thousands--around the lighthouse and Owen Point right now."




Well I left home at 5:00 am on Friday to reach Presqu'ile Provincial Park to photograph monarchs clustered there. While the reported 10,000 monarchs were very high and also filling the sky when I got there before sunrise at 6:45 am (I should have gotten there earlier!), I still got a couple of good shots. Neat to see.

I traveled on to a few spots west of this location on the south shore of Lake Ontario, and there was a strong continual movement of monarchs along the shoreline of Lake Ontario. At the Cranberry Marsh Hawk Watch, they were still passing by the hawk watch platform, but then about 11 am, they suddenly stopped and disappeared from the large field of goldenrod across the road. I suspect that the air had warmed up, the winds were out of the north, and they were blown and flew out over the lake - heading both across the lake and across to the next point of land which would be Toronto and Toronto Islands on the waterfront.
