yQVve Take a look out your window and you're bound to see a dinosaur or two—or at least the descendant of one. That little blue jay? Dinosaur. The obnoxious early rising crow? Dinosaur. The squirrel running up the tree? Well, that’s still a squirrel. But those feathered friends make your yard a real-life Jurassic Park.

Because various bird species tap-dance, moonwalk, and boogie to impress potential mates, it makes sense that dinosaurs did the same.
