This is for a story I'm writing. I can't find any information on how far various parrot species can travel without needing to land-- the closest I could find is this page saying that a macaw flies up to 15 miles looking for food. Intuitively I would think that larger birds, like macaws and African greys, would be able to fly farther than smaller ones due to having stronger wings, but the nonstop-flight record-holder is about the size of a robin so I guess that's not necessarily true.

Can anyone tell me how far various parrots can fly in a stretch, or at least the farthest that any parrot species can fly?
