Whistles the hits.

Cockatiel

Nymphicus hollandicus

Also called Quarrion, Weero, Weiro, Tiel

SpeciesDeep profile

From Mainland Australia. Wild birds range irregularly across the dry interior in every mainland state and territory, but not Tasmania, and stay away from the lush south-west and south-east corners and the harshest deserts. They favour semi-arid open woodland, acacia scrub, river red gum and coolibah country, grassland with scattered trees and farmland, always within reach of water.123

Looks how to spot one

Feathered; slim grey parrot with a tall wispy crest and a long pointed tail

The smallest member of the cockatoo family, with a slender build and a long tapering tail that accounts for about half of its total length and fans out in flight. The natural colouring is a soft brownish grey with a bold white panel on each wing and a round orange patch on each cheek. Adult males have a bright yellow face and crest and stronger orange cheeks, while females keep a greyer face and show fine barring under the tail. Young birds of both sexes look like females until their first moult at around six to nine months. The thin, gently curved crest moves up and down with the bird's mood.1246

Personality what they are like

Cockatiels are friendly, curious and a bit comical, and tend to form a close bond with their favourite person. Many enjoy perching on a shoulder and having the head and cheek feathers gently scratched, which mirrors how wild pairs preen each other. They prefer chirping and whistling to loud screeching, which is one reason they suit flats and first-time bird keepers. Whistling tunes comes more naturally to them than talking; some birds, usually males, learn a few words or phrases, and some copy household sounds or sing along with songs. In the wild they are shy birds that rely on speed and camouflage rather than confrontation, so a calm home suits them well.514

Daily activity how busy a day looks

A strong, fast flyer that benefits from regular, supervised time out of the cage every day, in a room made safe and away from other pets. Cockatiels are natural ground foragers, so scattering treats on paper on the cage floor or a play area gives them a satisfying way to search for food.54

Grooming and care the hands-on bits

Cockatiels produce powder down, a fine dust from their feathers, so regular cleaning around the cage and a well-ventilated room help. Offer regular chances to bathe or a light misting, keep perches of varied thickness to wear the nails naturally, and rotate toys to keep the bird busy. Keep the cage floor clean, as the bird spends time foraging there.15

Home where they are happiest

A cage large enough for the bird to stretch and flap its wings fully, with several perches, food and water bowls and toys. A wide front door helps, because cockatiels can be flighty and may panic if squeezed through a small opening. Place the cage in a lived-in room so the bird is part of family life.5

Food basics what goes in the bowl

In the wild cockatiels eat mostly small seeds gathered on the ground, especially acacia and grass seeds, plus crops such as wheat, sunflower and sorghum and some fruit and berries. At home a balanced diet is a good-quality pellet made for small parrots as the base, fresh vegetables and some fruit, and a small-seed mix given in moderation, with sunflower kept as an occasional treat. Fresh water every day.2453

Company who they like around

A very social flock bird that in the wild lives in groups from a handful to thousands, with pairs staying together all year. A pet cockatiel needs daily company, whether that is being talked to, gentle petting or simply sharing a room with its people, and many do well with another cockatiel for company.345

The story where it all began

Cockatiels come from the dry interior of Australia, where they are also known as quarrion and weero. European naturalists described the bird in the late 1700s, first Gmelin in 1788 and then Kerr in 1792, whose species name hollandicus refers to New Holland, the old Dutch name for Australia. In 1832 Wagler gave it its own genus, Nymphicus, a nod to the mythical nymphs, reflecting how charming early Europeans found it. Because it breeds readily in captivity, the cockatiel became one of the most widely kept pet parrots in the world and costs less than most other parrots. Breeders in the 20th century began fixing colour mutations: pied appeared in California in 1949, cinnamon in the 1950s, lutino in 1958 and pearl in 1967, and today more than twenty mutations are established, several found only in Australia. Modern genetic studies confirmed that the cockatiel, despite its parakeet-like shape, is a true cockatoo placed in its own subfamily.15

Fun facts for the dinner table

  1. 1

    It is the smallest member of the cockatoo family and the only species in its genus, Nymphicus.1

  2. 2

    The crest works like a mood signal: straight up when startled or excited, gently angled when relaxed, and flattened when the bird feels defensive.1

  3. 3

    Cockatiels are the only cockatoos that can breed before the end of their first year, and in the wild breeding is set off by seasonal rain.1

  4. 4

    The oldest confirmed cockatiel was reported to be 36 years old.4

  5. 5

    They can fly at more than 40 miles per hour (about 64 km/h) and use speed rather than fighting to escape predators.4

  6. 6

    The long tail makes up about half of the bird's length and spreads into a fan in flight.4

  7. 7

    The first colour mutation, pied, appeared in California in 1949; today over twenty mutations exist.1

  8. 8

    Their best-known flight call is a rolling whistled 'queel queel' or 'wee-rooo'.3

Recognised by the official bits

IUCN Red List
Least Concern. The wild population is described as abundant and stable, and seems to have gained from farm water points across its range.2
American Cockatiel Society
Founded in 1976 and describes itself as the oldest international cockatiel society in America. It serves both pet keepers and exhibitors and holds specialty shows.7
Taxonomy
Described by Gmelin in 1788 as Psittacus novaehollandiae and by Kerr in 1792 as Psittacus hollandicus. Wagler placed it in its own genus Nymphicus in 1832. Molecular work puts it in the cockatoo family Cacatuidae, in its own subfamily Nymphicinae.1

The care rhythm Furry Diary remembers it for you

Owner questions the things everyone asks

How often should I feed my Cockatiel?

Fresh food and water should be given every day. Furry Diary's starting plan is to refresh both daily. For exact amounts, check the food label and ask your vet.52 Furry Diary plan

What does a Cockatiel eat, and what should it never eat?

A balanced diet includes a good-quality pellet for small parrots, fresh vegetables, some fruit, and a small-seed mix in moderation, with sunflower seeds as an occasional treat. Never give avocado, chocolate, caffeine, alcohol, or high-salt foods; ask your vet for a full list.2453

How much space does a Cockatiel need?

The cage must be large enough for your cockatiel to stretch and flap its wings fully, with several perches, food and water bowls, and toys. A wide front door helps because they can be flighty. Place the cage in a lived-in room so your bird feels part of family life.5

What temperature, light or water does a Cockatiel need?

Keep your cockatiel in a calm, well-ventilated room away from drafts and direct sunlight. Fresh water should be provided every day. Specific temperature and lighting needs vary; consult your vet for tailored advice.524

How often should I clean a Cockatiel's home?

Furry Diary's starting plan suggests changing the cage liner every two days and doing a full cage clean once a week. Keep the cage floor clean since your bird forages there, and clean around the cage regularly due to powder down dust.15 Furry Diary plan

Can a Cockatiel live with others?

Yes, cockatiels are very social flock birds and do well with daily company from people or another cockatiel. Many enjoy living with a same-species companion, but always introduce new birds gradually and supervise interactions.345

How long does a Cockatiel live?

With good care, a cockatiel can live between 15 and 25 years. This long lifespan means they are a wonderful, long-term companion.1425

Can I handle a Cockatiel?

Yes, cockatiels are friendly and curious, and many enjoy perching on a shoulder and having their head and cheek feathers gently scratched. They benefit from regular, supervised time out of the cage every day, in a safe room away from other pets.514 Furry Diary plan
