Anyone who’d like to see how smart birds really are should come and meet the Stellar Jays that feed on the peanuts I put out on my second floor deck. They have apparently figured out that if they don’t see me through the windows wandering around upstairs, they are apt to find me by looking into my office windows downstairs. So they line up on the fence outside my office window and stare for a few minutes, then fly up to the tree branches over my deck, then return to the fence and stare at me again. This is my signal that I forgot to put the peanuts out. I dutifully stop what I’m doing and attend to their needs.
Yep, they have me very well trained.
