Number: 100

They’ve been here for a few days, flying around and roosting at night. It seems like there are more and more every day.

Editor's note: contacted observer for more details on this sighting

We’ve been counting them visually as they land to roost. When they are on lower limbs, we can just stand there and count them. Last night, though, we got out the binoculars to count them to double check.

The roosts we’ve seen start happening around 7 pm Eastern. The first one I noticed was on Friday, August 30th. That was the first day I looked for them, though, so they may have been here longer. We have noticed them off and on for years but no one was watching consistently for the past ten years because the house we now live in was previously sitting empty. They have been there every day since the 30th in varying numbers. The most we saw was on the day we counted 100 or so. There were multiple roosts that evening. Last night (9/5), there weren’t nearly as many. The farm where we live is pretty overgrown with clover, thistle and some milkweed so they have plenty of places to feed.

I’m not sure about overnight temperatures or wind direction, but the little grove where they have been roosting gets some evening sun and is shielded from the wind.
