We have a bird problem. Morning doves routinely shit on the boat (the Buick) from the Bradford pear trees that overhang the front driveway. So Grandpa decided he would order some mechanical owls. They play a recorded hooting whenever they sense movement. They hooted incessantly once they emerged from the box, predictably sensing our normal movements. Grandma insisted we hang them up immediately so the house would at least block some of the cacophony. Grandpa: What hooting? They don't hoot. You're hearing things. Grandma: They hoot over and over and over! Can't you hear it? Grandpa was playing a joke. He makes fun of senescence. If you care to know, the mechanical owls do not intimidate the morning doves. But it is funny to imagine the possibility of a morning dove formation swooping in on cue at night, unexpecting, to find their loitering tree taken by owls. Holy shit! Fly away, fly away, fucking owls man! Fly away fly away. Quick, about face. Shit! Owls!

Also if you care to know, the color of an owl's eyes indicate the time at which it hunts - black and brown for nocturnal owls, orangish for dusk, and yellow owls diurnal. The Elf Owl is 5 inches long, the Eagle Owl has a wingspan of over six feet and has been known to hunt young deer. Though usually solitary birds of prey, a group of owls is called a parliament.
