At what age is a baby parrot weaned?

This can vary quite a bit, and depends on the species of birds. Cockatiels and such small birds take up to six weeks. Pionus, Amazons, Greys and such medium size parrots are at least 3 months. Large parrots such as Cockatoos, macaws take at least 4 months. Hyacinth Macaws take longer up to 8 months to wean.
