Monarch Fall Roost
Sightings report image

Date: 09/14/2021

Number: 2000

Thousands were beginning to roost for the night beside a clover field. I have heard people talking about them being there at least over the last week.

[Additional information contributed by observer, added by Journey North, 09/16/21]:

Nighttime temps over the last week were mostly in the mid to upper 60's F*. The low point was 52* F on Sept. 10. And since 9/14, when I visited the site, the nighttime temps have dropped to the low 60's.

The monarchs were roosting in pines, small oaks, and other deciduous trees on the sheltered side of a path (almost tunnel-like) between rows of mostly pines and cedars, with fairly young deciduous trees mixed in.

I don't know when they first appeared. as far as I know, they are still there.
