The terror birds died out about two million years ago. Climate change could have contributed to the birds’ extinction. Or perhaps another predator even more terrible drove the birds to extinction. It is likely that increased competition from large predators caused the extinction. Continental drift and climate change created the Isthmus of Panama, connecting North and South America. That meant big predators from North America, like big cats, could out-compete the terror birds for food. We aren’t really sure what their closest living relatives are. Some scientists think cranes, while others think birds of prey. Experts disagree on when the last terror bird extincted. Some scientists argue 15,000 years ago. It is more likely they extincted 1.8 million years ago. Even if then, these were successful animals that survived over 50 million years. With climate change came habitat loss that may have sealed their fate. Along with extincted a massive lion, large horse, and elephants. The diet was small insects and mammals. Bigger animals were left for heavier relatives.
Why are they called terror birds?
Terror birds were flightless predatory birds that dominated South America for 60 million years. They stood 1-3 meters tall with large hooked beaks for killing prey. Most species had long legs and could run very fast. They were apex predators like lions and wolves today. Their closest living relative is the seriema, also from South America. Terror birds went extinct 2 million years ago, around the time North and South America merged. Large mammalian predators like sabre-tooth cats migrated to South America then, competing with terror birds.
What is the modern day terror bird?
The Terror Bird – also known as Phorusrhacos – was a large carnivorous bird. It was discovered in Santa Cruz, Argentina in 1887. It was nicknamed the Terror Bird. It lived about 12 million years ago.
Despite its huge size, the terror bird was faster than a modern horse. Terror birds grew to 10 feet tall. Phorusrhacos is the scientific name of this large bird. The name means “rag bearer”. However, the name Terror Bird is more commonly used. These monsters ruled South America for millions of years. The Phorusrhacos stood at over 10ft.
It is likely that the terror birds went extinct due to competition with large predators like saber-tooth tigers that migrated into South America. Terror birds disappeared about 2.5 million years ago. The seriemas are the only living relatives of the terror birds. Though the Black-legged Seriema spends time on the ground, it can make short flights.
Recently in Patagonian Argentina tracks were found. They are the first terror bird footprints. The prints hint that some birds kicked at prey and pinned it down.
To illustrate, terror birds were 2 – 3.6 meters tall. They used surprise attacks with beaks and talons. Seriemas are their closest relatives today. Seriemas are much smaller.
While “terror birds” were prehistoric creatures, the term has no link to terrorism in society. It is important to use language accurately when discussing topics, to avoid confusion.
How tall was a terror bird?
The largest terror bird was Kelenken guillermoi. It lived 15 million years ago in Argentina. Kelenken stood seven to ten feet tall. Its lower leg bone is 18 inches. It had a skull 28 inches long with a 45 centimeter beak.
Terror birds of South America likely went extinct due to increased competition with large predators like saber-tooth tigers and ancient wolves that migrated into South America through a land-bridge. Terror birds disappeared about 2.5 million years ago.
The seriemas are the only known living relatives of the terror birds. The Black-legged Seriema can make short flights into low trees.
The terror birds died out about two million years ago, around the time that North and South America merged at the Isthmus of Panama. Climate change could have contributed to the birds’ extinction. Perhaps another predator even more terrible drove the birds to extinction.
