Behavior/Health Concerns: Green-cheeked Conures need interesting entertainment and interaction. Feather picking and susceptibility to psittacine diseases are problems owners may encounter with this species of pet bird. Both breeders and pet owners favor the green-cheeked conure because it is typically a less expensive and quieter pet bird that is a successful breeder in captivity. Green-cheeked conures are also known for being gutsy. Some owners have witnessed them fearlessly taunting larger pet birds in the house, which means a green cheek's owner must be attentive when the birds are out of their cages. The green-cheeked conure species has three color mutations that have made it a popular pet bird. Cinnamon and yellow-side colors are growing in popularity, and the blue mutation is the newest, imported from Europe.
