Karl - Confiscated because no documents were available Karl and Zita, two gray parrots, were confiscated because the previous owner could not produce any documents. Since the end of October, the two intelligent gray parrots have been living in the bird house at Gut Aiderbichl in Henndorf. Grey parrots can live to be 60-80 years old. Both are three years old - the generations of our keepers will be able to do a good job for many years to come.
