The budgerigar, also known as the common parakeet, shell parakeet or budgie, is a small, long-tailed, seed-eating parrot. Naturally, the species is green and yellow with black, scalloped markings on the nape, back, and wings. Budgies are bred in captivity with colouring of blues, whites, yellows, greys, and even with small crests. Juveniles and chicks are monomorphic, while adults are told apart by their cere colouring, and their behaviour.
The cockatiel, also known as the weero/weiro or quarrion, is a medium-sized parrot that is a member of its own branch of the cockatoo family endemic to Australia. They are prized as household pets and companion parrots throughout the world and are relatively easy to breed compared to other parrots. As a caged bird, cockatiels are second in popularity only to the budgerigar.
Plumage is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these feather tracts are known by standardized names.
The colourful princess parrot is an Australian bird of the parrot family. Its name was given in honour of Princess Alexandra of Denmark, who in 1863 married the Prince of Wales Edward VII and eventually became Queen of the United Kingdom. Other names for the species include: Queen Alexandra parrot, Alexandra's parakeet, Princess of Wales parakeet, rose-throated parakeet, and spinifex parrot. Their plumage is mostly green with a pink throat, bluish crown and rump, and bright green shoulders.
The rosy-faced lovebird, also known as the rosy-collared or peach-faced lovebird, is a species of lovebird native to arid regions in southwestern Africa such as the Namib Desert. 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.
Fischer's lovebird is a small parrot species of the genus Agapornis. They were originally discovered in the late 19th century. They are named after German explorer Gustav Fischer.
A white horse is born predominantly white and stays white throughout its life. A white horse has mostly pink skin under its hair coat, and may have brown, blue, or hazel eyes. "True white" horses, especially those that carry one of the dominant white (W) genes, are rare. Most horses that are commonly referred to as "white" are actually "gray" horses whose hair coats are completely white. Gray horses may be born of any color and their hairs gradually turn white as time goes by and take on a white appearance. Nearly all gray horses have dark skin, except under any white markings present at birth. Skin color is the most common method for an observer to distinguish between mature white and gray horses.
The science of budgerigar color genetics deals with the heredity of mutations which cause color variation in the feathers of the species known scientifically as Melopsittacus undulatus. Birds of this species are commonly known by the terms 'budgerigar', or informally just 'budgie'.
The yellow-collared lovebird, 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.
The science of cockatiel colour genetics deals with the heredity of colour variation in the feathers of cockatiels, Nymphicus hollandicus. Colour mutations are a natural but very rare phenomenon that occur in either captivity or the wild. About fifteen primary colour mutations have been established in the species which enable the production of many different combinations. Note that this article is heavily based on the captive or companion cockatiel rather than the wild cockatiel species.
The Blue budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is part of the genetic constitution of the following recognised varieties: Skyblue, Cobalt, Mauve and Violet.
The Ino budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is the underlying mutation of the Albino and Lutino varieties and, with Cinnamon, a constituent mutation of the Lacewing variety.
The Clearflight Pied budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. It is the underlying mutation of the Continental Clearflight and Dutch Pied varieties. The Dark-eyed Clear variety results when the Recessive Pied and Clearflight Pied characters are combined.
Colours of the Syrian hamster can be described in three ways: as "self", "agouti" or "combinations". Self colours are a consistent coat colour with the same colour topcoat and undercoat. Agouti hamsters have a ticked coat, where each individual fur is banded in different colours. Agouti hamsters also have "agouti markings" which consist of dark cheek markings, a dark marking on the head, and a light underbelly. Combinations are produced when two self or agouti colours are present.
In poultry standards, solid white is coloration of plumage in chickens characterized by a uniform pure white color across all feathers, which is not generally associated with depigmentation in any other part of the body.
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and reddish pink or blue eyes. Individuals with the condition are referred to as albinos.
The Pied cockatiel is the first mutation of cockatiel colour genetics, with a mostly grey to light-yellow and white feathers and orange cheek patches.
The normal grey cockatiel, wild type cockatiel, wild cockatiel or grey cockatiel, or Common Cockatiel, is the origin cockatiel of all colour genetics mutations, with mostly grey feathers and orange cheek patches.
The white-faced cockatiel is one of the cockatiel colour genetic mutations, with a mostly white or grayish face. They stand out because they have no orange cheek patches or yellow coloring at all. This is the seventh established mutation which appeared for the first time with domesticated cockatiels in 1964 in Holland.
The bronze fallow cockatiel is a kind of cockatiel that sports red eyes. It was first seen in the bird house belonging to Irma Vowels in Florida. It is also known as fallow.
