Have you ever heard the guttural sounds of a pterodactyl? Close your eyes and listen to the cormorants, imagining the deep history of North America. In this short clip, you can hear a range of sounds produced by the cormorants nesting in giant cottonwood trees. You may ever spot some rhythmically pushing out calls or flying in with nesting material. *The “splats” you hear is the rain coming down and the whining/panting are from the dog*
