The gray parrot (Psittacus erithacus), also known as the Congo gray parrot, the African gray parrot, or the African gray parrot, is an Old World parrot in the family Psittacidae. The timneh parrot (Psittacus timneh) was once identified as a subspecies of the gray parrot but has since been upgraded to an entire species.

The Swedish naturalist Carl Linnaeus formally described the gray parrot in 1758 in the tenth edition of his Systema Naturae. He placed it with all other parrots in the genus Psittacus and coined the binomial name Psittacus erithacus. Linnaeus mistakenly identified the type of region as "Guinea": the region was later identified as Ghana in West Africa. The genus name is Latin for the word "parrot". The specific adjective Ertacus is Latin and is derived from the Ancient Greek εριθακος (Erithacus) for an unknown bird said to mimic human voices, possibly the red-black star. This type is unimodal: no subtype has been recognized. Timna was previously treated as a subspecies of the gray parrot. Still, it is now considered a separate species based mainly on the results of a genetic and morphological study published in 2007. Although Linnaeus placed all his known parrots in the genus Psittacus, only the gray parrot and a parrot Tmna are dedicated to this gender.
Distribution and habitat
The gray parrot is native to Equatorial Africa, including Angola, Cameroon, Congo, Gabon, Ivory Coast, Ghana, Kenya, and Uganda. This species is found in a range from Kenya to the eastern part of the Ivory Coast. Current estimates of the world's population are uncertain and range from 630,000 to 13 million birds. The population is declining all over the world. The species appears to prefer dense forests, but it can also be found in forest edges and in more open plant species, such as gallery forests and savannas.
A population study published in 2015 found that this species had been "virtually eradicated" from Ghana with populations declining by 90 to 99% since 1992. They were found in only 10 of 42 forested areas, and three roosts each with 700-1,200 birds. , now only 18 in total. Locals mainly blamed the pet trade and timber for the decline. The population is believed to be stable in Cameroon. In the Congo, an estimated 15,000 are taken annually from the pet trade, in the eastern part of the country, although the annual quota is 5,000.
Gray parrots have either escaped or were deliberately released to Florida, in the United States, but there is no evidence to suggest that the population is reproducing naturally.
Behavior and ecology
Wild bird behaviors:
Little is had some significant awareness of the way of behaving and exercises of these birds in nature. Notwithstanding an absence of exploration financing, it tends to be especially hard to concentrate on these birds in wild circumstances because of their status as prey creatures, which drives them to have to some degree cryptic characters. It has been shown that wild grays may likewise mimic various sounds they hear, very much like their hostage family members. Two grays were recorded while perching in Zaire and the scientists revealed that they had a collection of in excess of 200 distinct sounds, including nine impersonations of the melodies of other wild birds and one of a bat.
Diet:
They are generally frugivorous as the majority of their eating routine comprises of organic product, nuts, and seeds. The species inclines toward oil palm products of the soil eat blossoms and tree covering, as well as bugs and snails. In the wild, the dark parrot is somewhat a ground feeder. In bondage, they might be taken care of bird pellets, various natural products like pear, orange, pomegranate, apple, and banana, and vegetables like carrot, cooked yam, celery, new kale, peas, and green beans. They likewise need a wellspring of calcium.
Breeding:
Dark parrots are monogamous reproducers who home in tree depressions. Each mated sets of parrots needs its own tree for its home. The hen lays three to five eggs, which she broods for 30 days while being taken care of by her mate. The grown-ups guard their settling destinations.
Dark parrot chicks require taking care of and care from their folks in the home. The guardians deal with them until 4-5 weeks after they are fledged. Youthful leave the home at 12 years old weeks. Little is had some significant awareness of the romance way of behaving of this species in nature. They weigh 12-14 g (7⁄16-1⁄2 oz) at incubating and 372-526 g (13+1⁄8-18+1⁄2 oz) when they leave their folks.
Diseases
Youthful dark parrots are all the more usually tainted by psittacine mouth and plume infection than grown-ups. Contaminated birds might show side effects like loss of craving, cushy plumes, drowsiness, and decreased abilities to stroll because of fragile bones.
Conservation
Normal hunters for this species incorporate palm-nut vultures and a few raptors. Monkeys target eggs and the youthful for food. Dark parrots in bondage have been seen to be vulnerable to parasitic contaminations, bacterial contaminations, dietary deficiency, dangerous cancers, psittacine nose and plume illness, tapeworms, and blood-worms.
People are by a wide margin the biggest danger to wild dark populaces. Somewhere in the range of 1994 and 2003, a larger number of than 359,000 dark parrots were exchanged on the global market. Roughly 21% of the wild populace was being collected consistently. Death rates are incredibly high between the time they are caught and they arrive at the market, going from 60 to 66%. This species additionally is pursued for its meat and for its body parts, which are utilized in conventional prescriptions. Because of the broad collect of wild birds, notwithstanding environment misfortune, this species is accepted to go through a quick decrease in the wild and hence, has been evaluated as jeopardized by the International Union for Conservation of Nature.
In October 2016, the Convention on the International Trade of Endangered Fauna and Flora (CITES) broadened the most elevated level of security to dim parrots by posting the species under Appendix 1, which manages worldwide exchange the species.
In 2021, the Kenyan government held a short reprieve, during which dark parrot proprietors could pay a charge to get a license for their birds and work with lawful possession. Following the expiry of this time span, possessing this species without a permit is currently unlawful.
Relationship to humans
The species is normal in bondage and routinely kept by people as a buddy parrot, valued for its capacity to imitate human discourse, which makes it perhaps of the most well known avian pet. A got away from pet in Japan was gotten back to his proprietor subsequent to rehashing the proprietor's name and address.
Dark parrots are famous for mirroring commotions heard in their current circumstance and utilizing them resolutely. They are exceptionally smart birds, requiring broad conduct and social advancement as well as broad consideration in imprisonment or probably they might end up being troubled. Feather culling is a typical side effect seen among such troubled dim parrots, influencing up to 40% of hostage people. They may likewise be inclined to social issues because of their delicate nature. Social segregation rushes pressure and maturing
The dark parrot is an exceptionally friendly animal categories which depends on a herd type structure, in any event, when brought up in imprisonment. Since they are so subject to different birds inside their group, quite a bit of their discourse and vocal capacity is obtained through collaboration with the people with whom they dwell. Both wild and hostage parrots have been displayed to utilize contact calls, which permit them to collaborate with their group mates and convey data about their area, discovery of hunters, accessibility of food, and security status. Likewise, contact calls are utilized to major areas of strength for shape bonds with their herd mates, or on account of hostage grays, with their human housemates. In imprisonment, they have been displayed to show open skill, meaning they utilize human language accurately, yet in addition so that is fitting for the social circumstance which they are in.
Intelligence and cognition
Dim parrots are exceptionally insightful and are thought of as by quite a few people to be one of the most savvy types of psittacines. Numerous people have been displayed to perform at the mental level of a four-to six-year-old human kid in certain undertakings. A few investigations have been led, demonstrating a set-up of more significant level mental capacities. Tests have demonstrated the way that dim parrots can learn number arrangements and can figure out how to connect human voices with the essences of the people who make them. It has been accounted for that dim parrots are fit for involving existing known English words to make new marks for objects which the bird doesn't have the foggiest idea about the name. For instance "banerry" ("banana" + "cherry") for "apple", "banana wafers" for "dried banana chips" or "yummy bread" for "cake".
The American researcher Irene Pepperberg's exploration with Alex the parrot showed his capacity to learn in excess of 100 words, separating between objects, varieties, materials and shapes.[33] Pepperberg endured quite a few years working with Alex, and composed various logical papers on tests performed, demonstrating his high level mental capacities. One such investigation discovered that Alex been able to add numbers along with having a zero-like idea, like that of small kids and apes.[34]
Notwithstanding their striking mental capacities, dim parrots have shown selfless way of behaving and worry for other people. Scientists found that while blue-headed macaws were probably not going to impart a nut to different individuals from their own species, dim parrots would effectively give their conspecific accomplice a nut, regardless of whether it implied that they wouldn't have the option to get one themselves. At the point when the jobs were turned around, their accomplices were predominantly prone to give back, previous their own nut to their accomplice's advantages. This shows a presentation of benevolence as well as a demonstration of correspondence.
A recent report showed that hostage dark parrots have individual melodic inclinations. Whenever gave the potential chance to pick between two unique bits of music by means of a touch screen situated in their enclosure, the two birds in the test reliably picked various melodies, to which they then moved and chimed in. A few pet dim parrots have likewise been noticed utilizing the music component of brilliant speakers (like Alexa or Amazon Echo) to demand playback of explicit inclined toward melodies verbally.
Some exploration has demonstrated the way that foot inclination can be connected to the quantity of words a specific parrot might be aware and use. Specialists found that dark parrots who like to utilize their right foot showed an undeniable expansion in the quantity of words inside their vocabulary when contrasted with parrots who were left-footed. Researchers propose that parrots might have lateralization of mind capability, similar as well evolved creatures do.
Mutations
Dim changes happen normally in the wild, like the Blue Ino (pale skinned person), the Incomplete Ino, and the Blue varietals. The Blue Ino is all white. The Incomplete Ino has light pigmentation. The Blue has a white tail.
Reproducers from South Africa, Australia, New Zealand, and Scandinavia have reared grays seriously since the 1800s. These reproduced assortments incorporate the Red Pied, F2 Pied, Grizzles, Ino, Incomplete, Parino, Lutino, Cinnamon, and Red Factor. South African bird reproducer Von van Antwerpen and New Zealand accomplice Jaco Bosman chose F2 Pieds and made the main Red Factor Grays. They are uncommon, perhaps transcendently red-pigmented, and change in cost contingent on the degree of the red plumage showed.
