Behavior/Health Concerns:  White-bellied caiques are curious, so keep an eye on them. This pet bird can be nippy and prone to screeching if not given enough attention. They are generally a hardy species, but keep the cage floor clean because they like to play and bounce around on the cage floor. They are beaky birds and test things out with their beak, not actually biting but this can surprise or discourage new owners from this pet bird. While they do get along and interact well with other birds, white-bellied caiques can become aggressive toward other pet birds in the house.
