Feathers fly over bird row
The Danish owner is claiming that the bird cannot fly properly because of chronic gout and is demanding his money back from the Austrian seller through the courts.
The owner told the court: "When the cockatoo flies around all crooked, it's worthless."
The cockatoo took its test flight in a hall in front of the judge and a vet.
A report on the bird's health is expected to be produced in three to four months.
