September 4: Peak Migration
We had over a hundred Monarchs in the late afternoon — very breezy from the northwest. Many were feeding on the goldenrods and New England Asters in the pasture. Some would lift and leave with the wind to the southeast. There were some individuals that rested on seed heads of Gray-headed Coneflowers, then would return to feed.

September 5: Overnight Roost
We have a roost this a.m. with at least a hundred Monarchs, possibly more. Several roosting groups, some with 2 or 3 dozen and some with fewer. There are everal straggling groups of just 2-5 individuals — and many loners.
