Psittacus
''Psittacus'' is a genus of African grey parrots in the subfamily Psittacinae. It contains the two species: the grey parrot (''Psittacus erithacus'') and the Timneh parrot (''Psittacus timneh''). For many years, the grey parrot and Timneh parrot were classified as subspecies; the former as the nominate, the latter as ''P. e. timneh''. However, in 2012 the taxa were recognized as separate species by BirdLife International on the basis of genetic, morphological, plumage and vocal differences. These parrots are found in the primary and secondary rainforest of West and Central Africa. They are among the most intelligent birds in the world. They feed primarily on palm nuts, seeds, fruits, and leafy matter, but have also been observed eating snails. Their inclination and ability to mimic speech and other sounds have made them popular pets. Taxonomy The genus ''Psittacus'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' ...

Grey Parrot
The grey parrot (''Psittacus erithacus''), also known as the Congo grey parrot, Congo African grey parrot or African grey parrot, is an Old World parrot in the family Psittacidae. The Timneh parrot ''(Psittacus timneh)'' once was identified as a subspecies of the grey parrot, but has since been elevated to a full species. Taxonomy The grey parrot was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae''. He placed it with all the other parrots in the genus ''Psittacus'' and coined the binomial nomenclature, binomial name ''Psittacus erithacus''. Linnaeus erroneously specified the type locality (biology), type locality as "Guinea": the locality was later designated as Ghana in West Africa. The genus name is Latin for "parrot". The specific epithet ''erithacus'' is Latin and is derived from the Ancient Greek εριθακος (''erithakos'') for an unknown bird that ...

Timneh Parrot
The Timneh parrot (''Psittacus timneh''), also known as the Timneh grey parrot or Timneh African grey parrot, is a West African parrot. Formerly classified as a subspecies of the grey parrot ''Psittacus erithacus timneh'', it is now considered a full species ''Psittacus timneh''. In aviculture, it is often referred to by the initials TAG and is commonly kept as a companion parrot. Taxonomy The Timneh parrot was formally described in 1844 by the British zoologist and collector Louis Fraser. He coined the binomial name ''Psittacus timneh'' and specified the type locality as "Timneh country, Sierra Leone". The Temne are an ethnic group that are predominantly found in the Northern Province of Sierra Leone. The Timneh parrot was formerly classified as a subspecies of the grey parrot but is now treated as a separate species based on the results of a genetic and morphological study published in 2007. Two subspecies are recognised: * ''P. t. timneh'' Fraser, 1844 – south Guinea ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Psittacinae
Psittacinae is a subfamily of Afrotropical or Old World parrots, native to sub-Saharan Africa, which include twelve species and two extant genera. Among the species is the iconic grey parrot. The ''Poicephalus'' are usually green birds with different colored heads; the larger ''Psittacus'' are light grey with red tails. African parrots (at least the grey parrot) have been known in Europe since Roman times. The African parrots, unlike their Neotropical cousins, are polyphyletic: ''Agapornis'' of Africa and Madagascar was found to be the sister group to '' Loriculus'' of Australasia and Indo-Malayasia and together they clustered with the Australasian ''Loriinae'', ''Cyclopsittacini'' and '' Melopsittacus''. ''Poicephalus'' and ''Psittacus'' from mainland Africa formed the sister group of the Neotropical ''Arinae'' and '' Coracopsis'' from Madagascar and adjacent islands may be the closest relative of '' Psittrichas'' from New Guinea. Taxonomy This subfamily, together with its ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The Cambridge Declaration On Consciousness
Animal consciousness, or animal awareness, is the quality or state of self-awareness within a non-human animal, or of being aware of an external object or something within itself. In humans, consciousness has been defined as: sentience, awareness, subjectivity, qualia, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind. Despite the difficulty in definition, many philosophers believe there is a broadly shared underlying intuition about what consciousness is. The topic of animal consciousness is beset with a number of difficulties. It poses the problem of other minds in an especially severe form because animals, lacking the ability to use human language, cannot tell us about their experiences. Also, it is difficult to reason objectively about the question, because a denial that an animal is conscious is often taken to imply that it does not feel, its life has no value, and that harming it is not morally wr ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ...

Guinness Book Of World Records
''Guinness World Records'', known from its inception in 1955 until 1999 as ''The Guinness Book of Records'' and in previous United States editions as ''The Guinness Book of World Records'', is a reference book published annually, listing world records both of human achievements and the extremes of the natural world. The brainchild of Sir Hugh Beaver, the book was co-founded by twin brothers Norris and Ross McWhirter in Fleet Street, London, in August 1955. The first edition topped the best-seller list in the United Kingdom by Christmas 1955. The following year the book was launched internationally, and as of the 2022 edition, it is now in its 67th year of publication, published in 100 countries and 23 languages, and maintains over 53,000 records in its database. The international franchise has extended beyond print to include television series and museums. The popularity of the franchise has resulted in ''Guinness World Records'' becoming the primary international authority ...

World Parrot Trust
The World Parrot Trust is an international charity dedicated to saving parrots. History When the Trust was founded in 1989 at Paradise Park in Cornwall, UK, it was decided that the main objective was to promote the survival of all parrot species and the welfare of individual birds, both in the wild and in captivity. The Trust has achieved these aims by funding vital conservation work, research projects and educational programmes, both locally and internationally. Fundraising Over its nearly thirty-year span the Trust has raised some $2.0 M US and has used these funds to begin and support conservation and welfare projects in 43 countries for 70 species of parrot. The Trust has expanded globally to include national branches in Africa, Australia, Belgium, Canada, Italy, Netherlands, Scandinavia, Spain and the United States. Parrot Action Plan In 1999, the Trust joined with the IUCN to publish the Parrot Action Plan, to help protect 89 species of parrot from habitat destruction ...

Longevity
The word " longevity" is sometimes used as a synonym for "life expectancy" in demography. However, the term ''longevity'' is sometimes meant to refer only to especially long-lived members of a population, whereas ''life expectancy'' is always defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts). Longevity is best thought of as a term for general audiences meaning 'typical length of life' and specific statistical definitions should be clarified when necessary. Reflections on longevity have usually gone beyond acknowledging the brevity of human life and have included thinking about methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopia A utopia ( ) typically describes an imaginary community or society that ...

Monogamy
Monogamy ( ) is a form of dyadic relationship in which an individual has only one partner during their lifetime. Alternately, only one partner at any one time (serial monogamy) — as compared to the various forms of non-monogamy (e.g., polygamy or polyamory). The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. Terminology The word ''monogamy'' derives from the Greek μονός, ''monos'' ("alone"), and γάμος, ''gamos'' ("marriage").Cf. "Monogamy" in ''Britannica World Language Dictionary'', R.C. Preble (ed.), Oxford-London 1962, p. 1275:''1. The practice or principle of marrying only once. opp. to digamy now ''rare'' 2.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...
