In real life, birds are basically everywhere, and migration exists (and there’s a god damn “bald eagle’s” sound at Sandfall) So uh… What bird or other animal thing do you think that will be introduced in AO?
(Other than bears, they’re confirmed)
fourth shark
More sea creatures 
real we need the giant squids
(sea dragons?)
Abyssal creatures in general
It’s probably a hawk, actually.
You heard that the iconic USA sound is actually a hawk?
