How to arrange a bird aviary for multiple species?

When arranging an aviary for multiple bird species, ensure it's spacious enough to prevent crowding and aggression. Provide separate feeding and watering stations to reduce competition. Include varied perching options at different heights to accommodate each species' preferences. Offer plenty of hiding spots and nesting areas for privacy and security. Research compatibility between species to avoid predatory or aggressive pairings. Monitor the birds closely for signs of stress or conflict and be prepared to separate if necessary.
