Oops Upside Your Head

I bought these 'things' - what are they? I have no idea - in a charity shop in the summer and thought they'd look nice in my tree. Behind them hang the peanut feeders which I have to replenish every other day and each time I do I bash my head on these blinking things.

Every. Single. Time.
