Monarch Fall Roost
Sightings report image

Date: 08/29/2021

Number: 1000

There are large clusters of Monarchs in the trees surrounding our house. We have had a hundreds of them over the last 3-4 days.

[Additional information and photo contributed by observer, added by Journey North, 08/30/21]:
I believe there are 1000+ in the trees surrounding our house. I estimated the number by counting clumps of them hanging in the trees. Each group had 50-100 Monarchs. There were more than 10 groups of them and there were many more flying around as I counted. They were mostly hanging in our trees. Some were flying around the trees, but would then go back to roosting in the trees. I observed them for the last 3 days. They were still there this morning, although I believe the number to be lessening. I have not seen them nectaring on plants.

I observed them yesterday from 9am until about 1:30pm. The other days I observed them for approximately a half hour at a time at various times throughout the day. They have been roosting in our two birch trees, in our many maple trees, and also in some pines. I don’t know the type of pine, but could find out if helpful. Yesterday the breeze was about 15 mph and from the west. I am unsure of the wind the other days.
