The grey parrot, also known as the Congo grey parrot, is a medium to large bird from Africa.

It belongs to the family Psittacidae. These birds are highly valued as companions because they can mimic human speech. This ability makes them one of the most popular avian pets in the world. However, they are also highly intelligent animals that require significant social attention. Without regular interaction, they may experience stress or even begin plucking their own feathers.

Physically, the grey parrot is characterized by its predominantly grey feathers and a black bill. The feathers on the head and wings are generally darker than the rest of the body. Most head and body feathers feature slight white edges, and the tail feathers are a bright red. Adults typically have yellow irises surrounding dark pupils.

Juvenile birds look similar to adults, but their eyes are dark grey or black. Their undertail coverts are also tinged with grey. In the wild, these birds have an average lifespan of approximately 23 years. In captivity, they can live much longer, often reaching 40 to 60 years.

In their natural habitats, grey parrots are mainly frugivorous, meaning they eat mostly fruit. Their diet includes nuts, seeds, and oil palm fruit. They may also consume flowers, tree bark, insects, and even snails.

In the wild, they are partly ground feeders. When it is time to breed, these parrots are monogamous, meaning they form pairs with one partner. They nest in cavities found within trees. The female lays a brood of three to five eggs. She incubates these eggs for 30 days while her mate provides food. The chicks remain in the nest for 12 weeks before they are fledged. After they leave the nest, the parents continue to care for them for another four to five weeks.

The scientific history of the grey parrot began in 1758. A Swedish naturalist named Carl Linnaeus formally described the species in the tenth edition of Systema Naturae. He assigned it the binomial name Psittacus erithacus. Linnaeus originally thought the birds lived in Guinea, but it was later determined they were from Ghana in West Africa. For a long time, the Timneh parrot was considered a subspecies of the grey parrot. However, a 2007 study using genetic and morphological data proved they are separate species. Today, only the grey parrot and the Timneh parrot are assigned to the genus Psittacus.

Currently, the grey parrot faces serious conservation challenges. They are native to equatorial Africa, living in countries like Angola, Cameroon, the Congo, and Uganda. While global population estimates range from 630,000 to 13 million, numbers are declining. In Ghana, populations dropped by 90 to 99 percent between 1992 and 2015. This decline is largely due to the pet trade and the loss of timber forests. In the Congo, an estimated 15,000 birds are taken annually for the pet trade. The International Union for Conservation of Nature has rated the species as endangered. To help, the CITES agreement placed them under the highest level of protection in 2016.

One of the most fascinating aspects of the grey parrot is its advanced cognition. Many individuals perform tasks at the level of a four- to six-year-old human child. A famous researcher named Irene Pepperberg studied a parrot named Alex. Alex could learn over 100 words and differentiate between colors, shapes, and materials. He even showed a concept of zero and could perform basic addition.

Grey parrots can even invent new words. For example, a bird might combine "banana" and "cherry" to create the word "banerry" for an apple. They also show social intelligence through altruism. Studies show they will share food with a partner, and the partner will often return the favor.

Beyond speech, these birds have complex social and biological needs. They rely on a flock-type structure to communicate through contact calls. These calls help them share information about predators, food, and safety. In captivity, they can become sick from various issues, such as nutritional insufficiency or fungal infections. They are also sensitive to social isolation, which can hasten stress and aging. Even their musical tastes are unique. A 2012 study showed that captive grey parrots have individual musical preferences, choosing different songs and dancing along to them.
