Zita - Confiscated because no documents were available Zita and Karl, two gray parrots, were confiscated because the previous owner could not produce any documents. The two intelligent gray parrots have been living in the aviary at Gut Aiderbichl in Henndorf since the end of October. 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.
