So this is from left field. It has to do with an acorn woodpecker interaction, but with a NON-native avian species. Years ago in Grass Valley, CA, I free flew a Goffin's cockatoo (Cacatua goffiniana), on my property. There was an acorn woodpecker granary in a large digger pine,(Pines sabiniana). The cockatoo relished pulling the acorns out of the holes (he didn't eat them, however) that stored the food for the woodpeckers. The woodpeckers would waste no time "yelling" at the cockatoo and hazing him. The cockatoo stood his ground, but eventually did fly off screaming as he went with the woodpeckers close behind. So acorn woodpeckers are not afraid to take on whoever and whatever raids their larder. Good for them!
