When ‘Terror Birds’ Ruled the Earth
A bird known as Titanis walleri made its home in Florida just a few million years ago. Titanis, as its name suggests, was titanic indeed — a flightless predator, 5 feet tall, with a massive hooked bill. Titanis and other birds related to it belong to a group some paleontologists call the "terror birds." They were dominant land predators in South America for tens of millions of years. Paleontologists still aren’t clear about why Titanis and its kin went extinct. But whatever factors ended the era of the terror birds also made it a lot less risky to go out and fill your bird feeder.
