What would leave a half eaten apple on the tree?
For the last 4 days I've been losing about an apple a day from my William's Pride tree. I'm guessing that they are about 2 weeks from being ripe, so at this rate I expect to lose a good chunk of what's left (though I should still get a few). In addition to finding bits of core on the ground and empty zip lock bags, I've twice found half eaten apples still hanging on the tree. Both have been fairly low (see pic below), though the one I didn't get a pick of was about a foot higher.
have seen a groundhog and a rabbit in the yard, but haven't been able to catch either with apple cores, peanut butter, lettuce, or carrots for the last year. I do get squirrels and racoons, though for the last few days something has gotten good at stealing the bait without triggering the trap. Any suggestions on the likely culprit and how I can best neutralize it?
