The African grey parrot is one of the smartest animals alive, a 400-gram forest parrot that can use words for objects, colours and numbers and track hidden objects better than young children. Its hooked bill bites hard for its size, but on the absolute scale it is a small, unarmoured bird that wins by staying alert and flying away.
Detailed ratings
Research-backed ratings on one 0–100 scale for all 341 animals (updated 2026-09-28). How ratings work
Special abilities
Grey parrots do not just copy sounds: Alex used English labels for objects, colours, shapes and quantities to request, refuse and categorize, and trained greys have tried to direct their trainers as a problem-solving strategy (ADW). In a matchup this is situational awareness and flock communication, not damage.
A heavy hooked bill with an 84 N calculated bite (61–96 N by finite-element modelling) cracks oil-palm nuts and hard seeds and can deliver a painful defensive bite at close range.
Unique traits
A grey parrot outperformed 6- to 8-year-old children at tracking hidden objects through a series of swaps, matching adult humans on most test conditions.
Wild greys roost in large, noisy flocks and have been recorded with repertoires of over 200 call types, including imitations of other forest birds and a bat.
How it fights
Weapons
- The weapon is a heavy, hooked black bill backed by a calculated bite of about 84 N, used to crack oil-palm nuts and other hard seeds. That is roughly half the sulphur-crested cockatoo's calculated 167 N and a fifth of the scarlet macaw's 444 N. Zygodactyl feet grip and manipulate but are not talons. The bill can crush a finger or damage a small animal, but a 400 g bird cannot deliver much absolute force.
Struggles vs
- Only 400 g; far below any serious predator in absolute power.
- No protection beyond feathers.
- Partly a ground feeder, which exposes it at clearings.
- Wild populations are heavily depleted by trapping.

Fun facts
- Alex the grey parrot could label about 50 objects, 7 colours and 5 shapes, and count up to six.
- A grey parrot named Griffin beat 6- to 8-year-old children at a shell game and matched adults on most rounds.
- Grey parrots will hand a token to a partner so the partner can buy a treat, even with no reward for themselves.
- Two wild greys recorded at a roost in Congo used over 200 different calls, including nine imitations of other birds and one of a bat.
- A grey parrot can live 40–60 years in captivity.
- Flocks drop into forest clearings in waves so that the whole group is never on the ground at once.

W African Grey Parrot battle analysis
The African grey parrot is a medium-sized, red-tailed parrot of the African rainforest, and it has become the model for what a bird's mind can do. Decades of work with Alex showed that a parrot could learn English labels for objects, colours, shapes and quantities and use them to ask for things, refuse them and sort them into categories. Later tests found a grey parrot matching adult humans at a shell game, and captive greys voluntarily helping partners obtain food.
In the wild, those abilities serve a cautious forest life. Greys roost in large, noisy flocks over water, fan out by day to feed on oil-palm nuts and fruit, and drop into forest clearings in careful waves while sentinels watch the edges. Young birds stay with their families for years, learning which foods are safe and how to avoid palm-nut vultures and hawks. That same intelligence made the species a prized pet, and trapping has driven it to Endangered status.
As a fighter, the grey parrot is limited by size. Its bill produces about 84 newtons, enough to crack palm nuts and hurt a hand, but it is a 400-gram bird without armour or talons. It rates at the very top of the roster for Intelligence and well above average for Agility, while its Attack and Defense sit among the small birds.
Habitat & range
The grey parrot lives in the forest belt of central and West Africa, from the eastern border of Côte d'Ivoire through Ghana, Cameroon, Gabon and the Congo Basin to Uganda and Kenya, plus the island of Príncipe (ADW; Wikipedia). It prefers moist lowland forest but also uses forest edges, clearings, gallery forest, mangroves, wooded savanna, farmland and gardens, up to 2,200 m (ADW; World Parrot Trust). Escaped or released birds have been seen in South Florida since at least 1984, without evidence of breeding (Wikipedia).
Diet & hunting
Mainly fruit and nuts, especially oil-palm, supplemented with seeds, leaves, bark, flowers and some insects (ADW). The grey parrot is partly a ground feeder and regularly visits natural forest clearings: at one Congolese clearing an average of 40 birds arrived each day, perched and called in the surrounding trees, then landed to feed, drink and interact, with arrival times shaped by weather and season (Fastré et al. 2024). Natural predators include palm-nut vultures and several raptors (Wikipedia).
Social life
Highly social. Large single-species flocks roost together and break into smaller foraging groups by day. Each breeding pair holds its own tree within a loose colony. Young birds remain in family groups for years, socialize in "nursery trees", and learn food, water, predator and nest skills from adults (ADW).
Conservation
Endangered on the IUCN Red List since 2016 (Wikipedia; World Parrot Trust), with a decreasing and unknown wild population. More than 359,000 grey parrots were traded internationally between 1994 and 2003, and about 21% of the wild population was harvested each year; in 2016 CITES moved the species to Appendix I (Wikipedia). In Ghana, surveys found greys in only 10 of 42 forest areas, and roosts that once held 700–1,200 birds held 18 in total (Wikipedia).
