Not an Optional Extra Toys turn a house into a home. They bring fun and exercise into a bird's environment and help minimize boredom. In the wild, parrots spend their entire day finding food, choosing mates, raising young, and avoiding predators. Today's companion parrot doesn't do any of these things, and has everything done for him instead.
Toys are especially important for rescue birds.
While smaller shelters have the time to give each bird a considerable amount of attention, it becomes more important for birds to be able to entertain themselves when the number of birds rises. This is not to say that human contact is thrown over for toys, but there is a lot to be said for a bird that can entertain itself for a while. I can't believe there would even be a distinction. His brief stay at this foster home must have been hell. Simply put, they should have as many chew toys as they can possibly reduce to toothpicks, preening toys, puzzle toys, foot toys, interactive toys, and exercise toys.
