Housing yellow-headed amazon parrots, blue-fronted amazon parrots, black-headed parrots, green-thighed parrots, king parrots, and Senegal parrots.
Note: As the signage at Niendorf was horribly out-of-date (at almost all mixed-species exhibits, the signs mentioned species that clearly weren't there or failed to mention that species that clearly were there), I'll only note the species I saw and not the ones mentioned on the signs.
