Animal Dexterity
Lone assailant or teamwork? I don’t think the hummingbirds did this.
At least the raccoon(s) was/were polite enough to carefully leave the bottom of the feeder sitting on the railing instead of callously tossing it aside. I’m very curious about the mechanics of this operation—whether it was the work of one dexterous individual carefully unscrewing the base at the limits or their reach, or whether there was some kind of support from a friend (hanging on? standing on shoulders?) to make the work easier.

Rascally raccoons! I have friends who have to outwit them, as they get into the bait buckets.
