We're well over 20 but almost impossible to get an accurate count when they're all buzzing around as the sun is setting. We have three feeders out and they are 10 yards or so from a big crab apple tree. At any given time, there are 6-12 at the feeders and at least another dozen in the tree and buzzing around, in the open. I'd guesstimate we have 25-30 regulars.

I sit on the porch swing within a few feet of the feeders. As long as I am still, they buzz around my head as they constantly battle for position. Between the chrping and buzz of their wings, it is pretty chaotic. Sort of the bird version of George Floyd protests...
