Jackie Sparrow, the prematurely born bat that was adopted by Johnny Depp, is almost ready to fly and will one day be released back into the wild.

Little Jackie caught Depp's attention while he was on the Gold Coast filming the latest Pirates of the Caribbean movie.

Director of the Australian Bat League Trish Wimberley said the young bat's condition had improved since Depp came to visit the clinic.

"She's now hanging and flapping and trying to fly," she said.
