Congo African Grey parrot, Psittacus erithacus erithacus: these are larger birds (about 12 inches/30cm long) with light grey feathers, cherry red tails, and black beaks.

Timneh African Grey parrot, Psittacus erithacus timneh: these are smaller in size, have a darker charcoal gray coloring, a darker maroon tail, and a light, horn-coloured upper mandible.

The history of African Grey parrots kept as pets dates back over 4,000 years. Some Egyptian hieroglyphics clearly depict pet parrots. The ancient Greeks also valued parrots as pets. This custom was later adopted by wealthy Roman families who often kept parrots in ornate cages, and parrots were prized for their ability to talk. King Henry VIII of England also had an African Grey parrot. Portuguese sailors kept them as companions on their long sea voyages.
Today, many African Grey parrots are hand-reared by breeders for the pet trade, and they make wonderful and very affectionate companion parrots.

The Eclectus Parrot, Eclectus roratus is a parrot native to the Solomon Islands, New Guinea, northeastern Australia and the Maluku Islands (Moluccas).  The males of the species are bright green, having bright candy corn coloured upper mandibles and black lower mandibles, and blue or red tail and wing feathers; while the females are red headed and blue to purple breasted, with black beaks.

Eclectus parrots are one of the more popular birds kept in captivity, as either parent or hand reared.  The diet of the Eclectus in the wild consists of mainly fruits, unripened nuts, flower and leaf buds, and some seeds. A favorite fruit of the Eclectus is the pomegranate and papaya with seeds. In captivity, they will eat most fruits including mango, fig, guava, cherry, banana, any melons, stone fruits (peaches etc), grapes, citrus fruits, pears and apples.

An Amazon parrot is a large parrot of the genus Amazona native to the New World ranging from South America to Mexico and the Caribbean.

Most Amazons are predominantly green, with accenting colors that depend on the species and can be quite vivid. Amazons, like all parrots, are zygodactyl, having four toes on each foot—two front and two back.

They feed primarily on nuts and fruits, supplemented by leafy matter.  Amazons are known for their exceptional vocal abilities, playfulness, and dexterity with their feet. They are very loyal, loving companions; having them is somewhat like having a two-year-old human child in ability and temperament for 50-plus years. Since Amazons are cavity nesters in the wild, their desire to chew wood is strong, and they need to be provided with destructible toys to satisfy this innate urge.

Macaws are native to Mexico, Central and tropical South America. Most species are associated with forest, especially rainforest, but others prefer woodland or savanna-like habitats. 

Appetite: Macaws eat nuts and fruit. They also gnaw and chew on various objects. They show a large amount of intelligence in their behaviour and require constant intellectual stimulation to satisfy their innate curiosity.

Bonding: Macaws have been said to live for up to 100 years; however, an average of 50 years is probably more accurate. The larger macaws may live up to 65 years. They are monogamous and mate for life. In captivity unmated macaws will bond primarily with one person – their keeper. Pet macaws thrive on frequent interaction. 

Pionus is a genus of medium-sized parrots native to Central and South America. Characteristic of the genus are the chunky body, bare eye ring, (which can vary in color), and short tail. They are similar to Amazon parrots, only smaller. 

Pionus parrots are regarded as excellent pets, although some species are very rare in captivity. Most commonly kept species are the Blue-headed, Maximillian (Scaly-headed) and White-Capped.  Pionus parrots are known for their quiet (compared to other parrots) and reserved natures.  

Conures are either large parakeets or small parrots that are found in the western hemisphere. They are analogous in size and way of life to the Old World's Rose-ringed Parakeets or the Australian parakeets. All living conure species are found in Central and South America; the extinct Conuropsis carolinensis or Carolina Parakeet was an exception.

Despite being large for parakeets, conures are lightly built with long tails and small (but strong) beaks. Conure beaks always have a small cere and are usually horn-colored or black.  They are known as clowns of the parrot species because of their antics and the way they behave.

The Cockatiel (Nymphicus hollandicus), also known as the Quarrion and the Weero, is a diminutive Cockatoo endemic to Australia and prized as a household pet.

The only members of their genus, Cockatiels are now biologically classified as the smallest of the Cockatoo Family. These sweet-tempered birds are valued throughout the world as pets due to their gentle and sociable nature. These birds are found across the outback regions of inland Australia, and favour the Australian wetlands, scrublands, and bush lands.  The Cockatiel's lifespan in captivity is generally given as 15-20 years, though it is sometimes given as short as 12-15 years and there are reports of Cockatiels living as long as 30 years, the oldest confirmed specimen reported being 35 years old when it died.
