A companion parrot is a parrot kept as a pet that interacts abundantly with its human counterpart. Generally, most species of parrot can make excellent companions, but must be carefully managed around other common pet species like dogs and cats as they might be hostile towards them. Species of parrots that are kept as companions include large parrots, such as amazons, greys, cockatoos, eclectus, hawk-headed parrots, and macaws; (Species include hybrids like the Catalina macaw) mid-sized birds, such as caiques, conures, quakers, Pionus, Poicephalus, rose-ringed parakeets, and rosellas; and many of the smaller types, including Brotogeris, budgies, cockatiels, parakeets, lovebirds, parrotlets and lineolated parakeets. Some species of lories and lorikeets are kept as pets but are quite messy, and often more popular as aviary birds. Hanging parrots and fig parrots are normally kept as aviary birds and not as pets. Some species as pygmy parrots and kakapos, night parrots, and about half of the species of parrotlet, are not considered companion parrots due to difficult dietary requirements or unavailability. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (also known as CITES) has made the trapping and trade of all wild parrots illegal, because taking parrots from the wild has endangered or reduced some of the rarer or more valuable species. However, many parrot species are still common; some abundant parrot species may still be legally killed as crop pests in their native countries. Endangered parrot species are better suited to conservation breeding programs than as companions. Maintenance With the right home, parrots have the potential to make excellent, highly interactive, affectionate, and entertaining pets prized by their owners, but should not be considered easy care or low-maintenance pets. Tame companion parrots require daily attention and interaction with their owners, and need to be housed in a cage at least large enough to allow the bird to spread its wings and move about comfortably. Companion parrots also need to be fed a diet that includes fresh vegetables and fruits, and a smaller amount of seeds and grains; dietary requirements vary with species and activity level. Other elements essential to a companion parrot's well-being include appropriate toys to chew up and play with; veterinary care; and social time out of the cage whenever possible—preferably on playgyms or other out-of-cage perches. The larger parrots can be expensive to care for, messy, destructive, and loud, and some individuals may
