Mine are listening to music, playing video games, watching films and TV shows (on occasion), and napping (only the best hobbies for me!!)
I used to have a big bird feed ball dangling on the clothes line. This clothes line was from one wall to the other. It was so cool to see birds just taking nibbles.
Then a crow came along, cut the clothesline with its beak, and stole the whole ball feed ball and flew off.
Birds are legit assholes.
