Had a skunk visit yard at 4 am this morning, wandering around my fish pond, digging up a grub or two i guess. i know they can dig up your garden, but then they might also catch mice and other critters you dont want around. I don’t think they can catch my bluebirds, debating on whether to tolerate them or not.
As long as they aren’t building a den under a deck, in danger of spraying anyone, or visiting too regularly, maybe let them be?
Skunks might eat the eggs if they can get to them but otherwise I don’t think they pose a problem for the birds. They are actually pretty beneficial so, as you say, as long as they are not building a den close by things should be fine.
