Clusters were establishing upon arrival. Shuttle stop clusters started out at about 2 dz at 6:20pm & at 7:50 had grown to about 150.
Numerous monarchs were flitting about west path as I walked further south to Tip.
In interior monarchs flitted about but a cluster of about 25 was already established which grew to 40. There were numerous small clusters of up to 2-5-10, a couple at 25 & many individually roosting. Around 7:15pm a roost was being established on south side of their favorite Hackberry Tree which grew to about 200. It was established vertically from 25-50' up.
Only 1 monarch was seen nectaring on Woodland Sunflowers. Goldenrod is also plentiful.
All monarchs pristine & a good mix of males & females.
Monarchs roosted on Hackberry trees, bare branches & Grapevine.
I use binoculars, camera & clicker to count.

Tropical Depression IDA (previously hurricane) was also passing south of Lake Erie.
