Agapornis
Lovebird is the common name for the genus ''Agapornis'', a small group of parrots in the Old World parrot family Psittaculidae. Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar. Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and the long periods which paired birds spend sitting together. Lovebirds live in small flocks and eat fruit, vegetables, grasses, and seeds. Some species are kept as pets, and several coloured mutations have been selectively bred in aviculture. The average lifespan is 10 to 12 years. Description Lovebirds are in length, up to 24 cm in wingspan with 9 cm for a single wing and in weight. They are among the smallest parrots, characterised by a stocky build, a short blunt tail, and a relatively large, sharp beak. Wildtype lovebirds are mostly green with a variety of colours on their upper body, dependin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rosy-faced Lovebird
The rosy-faced lovebird (''Agapornis roseicollis''), also known as the rosy-collared or peach-faced lovebird, is a species of lovebird native to the Namibian savanna woodlands. Loud and constant chirpers, these birds are very social animals and often congregate in small groups in the wild. They eat throughout the day and take frequent baths. Coloration can vary widely among populations. Plumage is identical in males and females. Lovebirds are renowned for their sleep position in which they sit side-by-side and turn their faces in towards each other. Also, females are well noted to tear raw materials into long strips, "twisty-tie" them onto their backs, and fly substantial distances back to make a nest. These birds are common in the pet industry. Taxonomy It was described by the French ornithologist Louis Pierre Vieillot in 1818. It was originally named ''Psittacus roseicollis'' but later moved to the genus ''Agapornis'' with the other lovebirds. Two subspecies are recognised: ...

Yellow-collared Lovebird
The yellow-collared lovebird (''Agapornis personatus''), also called masked lovebird, black-masked lovebird or eye ring lovebird, is a monotypic species of bird of the lovebird genus in the parrot family Psittaculidae. They are native to Arusha Region of Tanzania and have been introduced to Burundi and Kenya. Although they have been observed in the wild in Puerto Rico, they are probably the result of escaped pets, and no reproduction has been recorded. They have also been observed in Arizona. Description The yellow-collared lovebird is a mainly green small parrot about 14.5 cm (5.5 in) long. Its upperparts are a darker green than its lower surfaces. Its head is black, and it has a bright red beak with white above it and white eyerings. Yellow on the breast is continuous with a yellow collar and an expansion of yellow over the nape of the neck. Male and female have an identical external appearance. Breeding During courtship, the male bird moves his head up and down and ...

Black-collared Lovebird
The black-collared lovebird (''Agapornis swindernianus'') also known as Swindern's lovebird is a small, 13.5cm (5in) long, African parrot in the genus ''Agapornis'' and belongs to the Agapornithinae family. The black-collared lovebird is widespread across the African tropical closed rainforest. It is a mostly green parrot with black band on the back of its neck, and a dark greyish-black bill. Both sexes are similar. It is rarely kept in captivity because of its dietary requirement for a native fig. Description It is a mostly green parrot with black-collared nape, brownish red chest, greyish black bill, yellow iris and grey feet. Both sexes are similar. More specifically, the head is mostly green, with a yellow neck and a narrow black hind collar. Its bottom is a royal dark blue, and the rest of its upper body is dark green. The ''Agapornis swindernianus'' has soft black feathers and orange-red markings on its outer tail feathers. The two sexes are similar in their coloring. ...

Parrot
Parrots (Psittaciformes), also known as psittacines (), are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genus (biology), genera, found mostly in tropics, tropical and subtropics, subtropical regions. The four families are the Psittaculidae (Old World parrots), Psittacidae (African and New World parrots), Cacatuidae (cockatoos), and Strigopidae (New Zealand parrots). One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk (Red List Index, IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperateness, temperate regions as well. The greatest biodiversity, diversity of parrots is in South America and Australasia.

Psittaculidae
Psittaculidae is a family of parrots, commonly known as Old World parrots, though this term is a misnomer, as not all its members occur in the Old World and Psittacinae also occurs in the Old World. It consists of six subfamilies: Psittrichasinae, Agapornithinae, Loriinae, Platycercinae, Psittacellinae and Psittaculinae. Taxonomy The following cladogram shows how the family Psittaculidae relates to the three other families in the order Psittaciformes. The tree is based on the work by Leo Joseph and collaborators published in 2012 but with the choice of families and the number of species in each family taken from the list maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC), now the International Ornithologists' Union. Joseph and collaborators proposed that the genera '' Psittrichas'' and '' Coracopsis '' should be placed in their own family, Psittrichasidae. This proposal has not been adopted by taxon ...

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...
