pet parrots do get away from their owners quite often. the people buy the birds with their flight feathers clipped and do not realize the birds will moult the cut feathers as though they were broken and grow new ones.
the owner is out side with the bird and all of a sudden the bird tries it's wings and it is gone. professionally trained birds can be trained to free flight and return to their owners, but it is not something birds usually do. they are basically wild animals.
as they fly around they are looking for another bird of their specie and the next thing you know, over a couple of years you have a flock that flies together.
toby and i went to monrovia where birds seemed to have settled and you can see pairs of keets, cockatials, macaws, and flocks of amazons that hang around the trees near the library because people feed them there.
i would not try to touch one of these. they have reverted to their natural state and are wild and will bite.
it is a fasciating city to visit if you like to see wild birds really wild.
