I’ve been noticing these marks the last few days, and the owl observed on Sunday and heard periodically in the lantern hours (pretty sure it’s the same one) flew to right above here…so…owl evidence.
The other evidence is that these leaves are all tulip poplar leaves, so we can surmise that it’s their time to fall.
If that’s not enough, I did a long walk (for me) and a shortish walk, and also perambulated down the street to Book Club (and back)…and the (generous) fitness device is reporting 6K steps. Victory! [Ankle tired, however—not surprisingly. I took all outdoor walks with the walking poles.]
