I heard a story of a player (a hunter) who tamed one of these purposefully for use in PVP fully believing that people would not attack his pet because it was USA's national symbol. While that is a nice thought: a. not just U.S. citizens play the game (even on U.S. servers) and b. PVP-ers tend not to be the animal-hugging / sentimental sort... needless to say, he was sorely disappointed.
Bald Eagle (Haliaeetus leucocephalus)
Bald Eagles are only found in North America and are second in size only to the Golden eagle in the U.S. Bald Eagles are found throughout most of North America, from Alaska and Canada to northern Mexico. About half of the world's 70,000 bald eagles live in Alaska. Bald eagles are solitary, but monogamous animals. Although they spend winters and migrations alone, bald eagles maintain the same breeding pair year after year.
Rocs
Haast's Eagle
Rocs are a giant legendary bird of prey, sometimes portrayed as all white in color. Some believe they were based off of the Haast's Eagle (Harpagornis moorei) a species of massive eagles that once lived on the South Island of New Zealand. The species was the largest eagle known to have existed, weighing up to 30lbs with a 10ft wingspan and flight speeds of up to 50mph.
Owls
Owls
The Eagle Owl (Bubo bubo) is the largest species of owl, weighing up to 10 lbs. 216 species of owls exist today, and of these 18 belong to the Barn Owl family (Tytonidae) and 198 belong to the typical owl family (Strigidae). Below is the Great Horned Owl (Bubo virginianus)
Barn Owl (Tyto alba) - I hope they incorporate the Barn Owl into the game, they have such beautiful faces.
Vultures
There are 22 species of vultures, split between old world and new world varieties. Primarily carrion eaters, they help clean up the animal carcases that larger predators leave.
The vulture's bald head lacks feathers that would be a breeding ground for bacteria and so the lack of feathers is a brilliant physiological property that allows vultures to plunge into all sorts of carcasses, and come out clean.
