Courtship in owls is like this. No strutting around or flashing of splashy, colorful feathers, mostly just mutual hooting. “If you’re an owl, you’ve got to sing to attract a mate,” says Holt. “Big owls hoot. Little owls toot. That’s their whole thing, vocalizations.” But what hooting it can be, the choicest and most persuasive owl language.
