Our nearest neighbor has 8 acres. We have 2.4. Other neighbors have two+ acre lots. And these lots are mostly kept native, and are covered with many dozens of scrub oak trees. So this neck of the woods can support - I don't know - maybe 200 squirrels. Maybe ten times that. The idea of moving this many squirrels just depresses me.
The shotgun idea sounds like fun except for the fact that we are very much in town. Long before I shot 200 squirrels I'd be relocated, I fear. Also, I don't have a good recipe for squirrel fricasee.
Hoping the barn owls move in soon.

The stamens of Golden Wings (per a photo in Botanica's Roses) look a lot like the ones on the mystery rose, with red filaments and yellow anthers. The color of the flower looks a little closer to White Wings. They are both good guesses. (And White Wings was a new rose to me.) I guess it could also be Mermaid, though its foliage is not as glossy as I'd expect for that rose.
