This may be the wrong forum, but I'm just looking for anyone who has seen the same thing. I'm in the Sacramento Valley. I have a very eclectic garden to look onto from my back terrace. The jays have always been aggressive toward each other spending an entire day in argument and ruffled feathers, It's rather exhausting. Now they're attacking the squirrels. Two jays in the orange tree taking turns harrassing one squirrel by flying right at him and actually hitting him with their wings or feet. Is this normal?
