Monster Birds Of The Americas

For most of modern human's existence, say over the past 50,000 to 100,000 years, if we saw something fly under its own power, it was a bird, a bat or an insect - maybe a 'flying' fish or 'flying' fox if you want to stretch things a bit. Relatively few of these feature prominently in any culture's mythology. Bats might have an association with vampires, but your average run-of-the-mill garden variety bird is usually taken for granted - unless they are monstrous in size and like humans for dinner.
