Eye pinning, also known as eye flashing [1] or eye blazing, is a form of body language used by parrots. The term that refers to the rapid and very conspicuous dilation and constriction of the pupils of the bird's eyes in response to an external stimulus. Unlike humans, parrots are able to control this reflex and use it as a form of nonverbal communication. [2] It is a common behavior in amazons, macaws, Poicephalus species and the African grey parrots. [3]
It can be an indication that the parrot is feeling excited, angry, afraid or is interested in something. In some circumstances, it may also be a warning that the parrot is currently in a state of being where it will bite if touched. [4] Male budgerigars will perform eye pinning as part of their courtship behavior, pinning the eyes while singing, fluffing and head bobbing, [5] while amazon parrots may pin their eyes to show excitement during play, alongside a fanned tail and raised head and neck feathers. [6]
In the Panama amazon, eye pinning has been noted during vocal communication with humans. The parrot's eyes were observed to noticeably contract when talking or mimicking other sounds of human origin, video recordings indicating that the pupils began contracting several milliseconds prior to the utterance, perhaps suggesting some sort of 'internal rehearsal' process. This was not seen to be the case in the experiment with innate parrot sounds such as short squawks, neither was this behavior observed in a non-talking blue-fronted amazon. In certain circumstances, eye pinning would also occur when the bird heard specific favored words or sounds from humans. [7]
This behavior has also been observed in domestic chickens and woodpigeons. [8] [9]
Amazon parrots are parrots in the genus Amazona. They are medium-sized, short-tailed parrots native to the Americas, with their range extending from South America to Mexico and the Caribbean. Amazona is one of the 92 genera of parrots that make up the order Psittaciformes and is in the family Psittacidae, one of three families of true parrots. It contains about thirty species. Most amazons are predominantly green, with accenting colors that depend on the species, and they can be quite vivid. They feed primarily on seeds, nuts, and fruits, supplemented by leafy matter.
The budgerigar, also known as the common parakeet, shell parakeet or budgie, is a small, long-tailed, seed-eating parrot. Budgies are the only species in the genus Melopsittacus. 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 rose-ringed parakeet, also known as the ringneck parrot or the Kramer parrot, is a medium-sized parrot in the genus Psittacula, of the family Psittacidae. It has disjunct native ranges in Africa and the Indian Subcontinent, and is now introduced into many other parts of the world where feral populations have established themselves and are bred for the exotic pet trade.
Alex was a grey parrot and the subject of a thirty-year experiment by animal psychologist Irene Pepperberg, initially at the University of Arizona and later at Harvard University and Brandeis University. When Alex was about one year old, Pepperberg bought him at a pet shop. In her book "Alex & Me", Pepperberg describes her unique relationship with Alex and how Alex helped her understand animal minds. Alex was an acronym for avian language experiment, or avian learning experiment. He was compared to Albert Einstein and at two years old was correctly answering questions made for six-year-olds.
The yellow-naped amazon or yellow-naped parrot is a widespread amazon parrot sometimes considered to be a subspecies of the yellow-crowned amazon. It inhabits the Pacific coast of southern Mexico and Central America. It has been recently been reclassified as Critically Endangered by the IUCN Red List due to a dramatic decline across the extent of its range. Yellow-naped amazons have lost more than 92% of their population over the last three generations.
The blue-fronted amazon, also called the blue-fronted parrot, the turquoise-fronted amazon and the turquoise-fronted parrot, is a South American species of amazon parrot and one of the most common amazon parrots kept in captivity as a pet or companion parrot. Its common name is derived from the distinctive blue/turqoise marking on its head just above its beak.
Caique refers to a group of four species of parrots in the genus Pionites endemic to the Amazon Basin in South America.
A companion parrot is a parrot kept as a pet that interacts abundantly with its human counterpart. Generally, most species of parrot can make excellent companions, but must be carefully managed around other common pet species like dogs and cats as they might be hostile towards them.
The white-fronted amazon also known as the white-fronted parrot, or spectacled amazon parrot, is a Central American species of parrot. They can imitate a range from 30 to 40 different sounds. Like other large parrots, the white-fronted parrot has a long potential life span, usually around 40 years.
The red-crowned amazon, also known as the red-crowned parrot, green-cheeked amazon or Mexican red-headed parrot, is an endangered amazon parrot native to northeastern Mexico and possibly southern Texas in the United States. A 1994 study estimated wild populations of between 2,000 and 4,300 mature individuals; the IUCN Red List considers it a globally endangered species with a decreasing population. The main threats to the native bird's survival are the illegal export of trapped birds from Mexico to the United States for the pet trade and the destruction of their natural habitat, the lowland forests of northeastern Mexico.
The yellow-headed amazon, also known as the yellow-headed parrot and double yellow-headed amazon, is an endangered amazon parrot of Mexico and northern Central America. Measuring 38–43 centimetres (15–17 in) in length, it is a stocky short-tailed green parrot with a yellow head. It prefers to live in mangrove forests or forests near rivers or other bodies of water. It is sometimes considered a subspecies of the yellow-crowned amazon. It is a popular pet and an excellent talker. Poaching for the international pet trade has driven the species to near-extinction in the wild; around half of all wild-caught birds are thought to die in the process.
A birdcage is a cage designed to house birds as pets.
Talking birds are birds that can mimic the speech of humans. There is debate within the scientific community over whether some talking parrots also have some cognitive understanding of the language. Birds have varying degrees of talking ability: some, like the corvids, are able to mimic only a few words and phrases, while some budgerigars have been observed to have a vocabulary of almost 2,000 words. The hill myna, a common pet, is well known for its talking ability and its relative, the European starling, is also adept at mimicry. Wild cockatoos in Australia have been reported to have learned human speech by cultural transmission from ex-captive birds that have integrated into the flock.
The black-capped parakeet, also known as the black-capped conure or rock conure in aviculture, is a parrot native to the south-western Amazon Basin and adjacent east Andean slopes in Peru, Bolivia and Brazil. It has a total length of approximately 25 cm. It is mostly green with off white scalloping on the hindneck and breast and red primary coverts.
The Hispaniolan parrot, also known as Hispaniolan amazon, is a species of psittaciform bird of the family Psittacidae endemic to Hispaniola, which includes the Dominican Republic and Haiti. Its white forehead, light beak, white eye-ring, blue ear patch, and maroon belly patch are the main features that differentiate it from other amazons. Its body measures about 28 centimeters in length. A typical adult weighs 250g (8.75 oz).
Parrots (Psittaciformes), also known as psittacines, are birds with a strong curved beak, upright stance, and clawed feet. They are made up of four families that contain roughly 410 species in 101 genera, found mostly in tropical and subtropical regions. The four families are the Psittaculidae, Psittacidae, Cacatuoidea (cockatoos), and Strigopidae. One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions as well. The greatest diversity of parrots is in South America and Australasia.
The Timneh parrot, 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.
The grey parrot, 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.
The northern mealy amazon or northern mealy parrot is among the largest parrots in the genus Amazona, the amazon parrots. It is a mainly green parrot with a total length of 38–41 cm (15–16 in). It is endemic to tropical Central America. This parrot and the southern mealy amazon have previously been considered conspecific.
Chronic egg laying is a maladaptive, behavioural disorder commonly seen in pet birds which repeatedly lay clutches of infertile eggs in the absence of a mate. It is particularly common in cockatiels, budgerigars, lovebirds, macaws and amazon parrots. Birds exhibiting chronic egg laying behavior will frequently lay eggs one after the other without stopping to brood them once the typical clutch size for their particular species has been reached. Excessive egg laying places a strain on the hen's body, depleting resources such as calcium, protein and vitamins from her body and may lead to conditions such as egg binding, osteoporosis, seizures, prolapse of the oviduct, or peritonitis – which may lead to her death.
