The woodpeckers here generally seem to just yell at me, when I get to close to where they’re pecking. Squirrels too if I’m close to where they’re eating or collecting acorns or hickory nuts off the trees. Sometimes they pelt me with hickory nut shells.
Got a lot of Mocking birds this year including one who mocks the cat. It’s the funniest thing because the cat gets mad, lays down on top of paws, pulls in head and scowls. Even more so when I LOL at him.
Cats do not like to be “mocked”, no pun intended!
We have mockingbirds nesting in a holly tree in the yard, seems to be every year. Any animal/bird that comes near is going to be dive bombed & harassed until it leaves the area. It’s entertaining to watch them.
