I grow ever bearing strawberries on my 2nd story porch in containers, something has eaten 2 of my first 3 ripe strawberries. i haven’t seen any pests so suspect birds, but cant find any pictures of what bird nibbles would look like….can someone help identify what might be getting at my strawberries?

really hoping not a rodent. i put bird netting up around the plants tonight to hopefully deter whatever it is.
