Black Friday belonged to the Blue Jays - the Squirrels retaliated 'big time" the next day.
My wife had jokingly suggested that we might have to run an ad in "Critter Daily" to announce opening of the feeders. Apparently the daily did have an ad {placed by the Squirrels} - or even an article - in the Black Friday edition. My wife counted five squirrels in our yard at one time. In any case, the Jays were badly out-numbered. Every place they went, there was already a Squirrel. Unless I zoomed in, I had a hard time getting just one Squirrel in any photo. She commented that it was hard to determine which Squirrels had enough to eat - or even any - without a nametag - but I stuck to my rule of filling the Feeders only once during the day.
We haven't seen that many since then. Perhaps the 'hungry' Squirrels went elsewhere, but the Squirrels made their point. The birds stick mostly the the Bird Feeder and the Squirrels to the Squirrel Feeder - the birds certainly do not squeeze the Squirrels out when it comes to peanuts in the Squirrel Feeder.
