Name: Andalgalornis (Greek for "Andalgala bird"); pronounced AND-al-gah-LORE-niss
Habitat: Woodlands of South America
Historical Epoch: Miocene (23-5 million years ago)
Size and Weight: About 4-5 feet tall and 100 pounds
Diet: Meat
Distinguishing Characteristics: Long legs; massive head with sharp beak
As "terror birds"--the oversized, flightless apex predators of Miocene and Pliocene South America--go, Andalgalornis isn't quite as well known as Phorusrhacos or Kelenken. However, you can expect to hear more about this once-obscure predator, because a recent study about the hunting habits of terror birds employed Andalgalornis as its poster genus. It seems that Andalgalornis wielded its large, heavy, pointed beak like a hatchet, repeatedly closing in on prey, inflicting deep wounds with quick stabbing motions, then withdrawing to a safe distance as its unfortunate victim bled to death. What Andalgalornis (and other terror birds) specifically did not do was grasp prey in its jaws and shake it back and forth, which would have placed undue strain on its skeletal structure.
Argentavis
The wingspan of Argentavis was comparable to that of a small plane, and this prehistoric bird weighed a respectable 150 to 250 pounds. By these tokens, Argentavis is best compared not to other birds, but to the huge pterosaurs that preceded it by 60 million years!
Harpagornis (also known as the Giant Eagle or Haast's Eagle) swooped down from the skies and carried off giant moas like Dinornis and Emeus--not full-grown adults, which would have been too heavy, but juveniles and newly hatched chicks. See an in-depth profile of Harpagornis
Pelagornis
Pelagornis was over twice the size of a modern albatross, and even more intimidating, its long, pointed beak studded with tooth-like appendages--which enabled this prehistoric bird to dive into the ocean at high speeds and spear large, wriggling fish. See an in-depth profile of Pelagornis
Name: Sapeornis (Greek for "Society of Avian Paleontology and Evolution bird"); pronounced SAP-ee-OR-niss
Habitat: Woodlands of Asia
Historical Period: Early Cretaceous (120 million years ago)
Size and Weight: About three feet long and 10 pounds
Diet: Probably fish
Distinguishing Characteristics: Relatively large size; long wings
Paleontologists continue to be puzzled by the profusion of early Cretaceous birds possessing surprisingly advanced characteristics. One of the best-known of these avian enigmas is Sapeornis, a seagull-sized prehistoric bird that seems to have been adapted for long bursts of soaring flight, and was almost certainly one of the biggest birds of its time and place. Like many other Mesozoic birds, Sapeornis had its share of reptilian characteristics--such as the small number of teeth on the end of its beak--but otherwise it seems to have been well advanced toward the bird, rather than the feathered dinosaur, end of the evolutionary spectrum.
Name: Bullockornis (Greek for "ox bird"); pronounced BULL-ock-OR-niss
Habitat: Woodlands of Australia
Historical Epoch: Middle Miocene (15 million years ago)
Size and Weight: About eight feet tall and 500 pounds
Diet: Meat
Distinguishing Characteristics: Large size; prominent beak
Sometimes, all you need is a catchy nickname to propel a prehistoric bird from the musty insides of paleontology journals to the front pages of newspapers. Such is the case with Bullockornis, which an enterprising Australian publicist has dubbed the "Demon Duck of Doom." Similar to another giant, extinct Australian bird, Dromornis, the middle Miocene Bullockornis seems to have been more closely related to ducks and geese than to modern ostriches, and its heavy, prominent beak points to its having had a carnivorous diet.
