Observed large clusters of monarchs while walking the path along Lake Erie at McGeachy Pond Conservation Area near Erieau, Ontario.

Editor's note: contacted observer for more details on this sighting

We observed the roost at approximately 7 p.m.

We did a "head count", as there were several trees and limbs that were visible to us with monarchs on them.

I think there was some golden rod about 1/10 mile away.

Guestimate overnight temps at high 50s.

Unsure of wind direction. The monarchs were shielded from the wind.

FYI- The next morning we went back to check on them at 10 am and the sun was shining on the roost. Temps were approximately 60 degrees in the sun. About 2/3 had left the area and seemed to be following the Lake Erie shore, heading SW.

We were constantly dodging monarchs as we drove along Rt. 3, near Lake Erie, heading SW. Once we headed NW towards Hwy 401 we didn't see any monarchs.
