Seen dozens of roosting monarchs. According to the neighbour, it is the first roosts of this year in the park.

It was Saturday morning at dawn, overcast(later in the morning it rained). Wind was coming from the south west which a few were trying to leave the trees it looks like, but went back or only went as far as one tree over. The park is at the bluffs along lake huron so there is goldenrod, sumac but not many native wild sources but a few gardens with black eyed Susan's, hydrangeas, and a few annuals. The "butterfly garden" in the park only has goatsbeard, pink turtlehead, and catmint which are not great nectar plants especially in fall.
Overnight it was I think 17°C, about 25° by daylight.
They were roosting on the north east sides of the trees. I went back yesterday at 4pm(September 1) and there were only a few in the park. I am attempting to find who cares for the park to add a garden that will be more enjoyed by the butterflies.

Editor's note: Editor's note: We've re-dated this report from 8/29 to 8/28, the night the roost formed.
