The cockatiel (Nymphicus hollandicus), also known as the weero/weiro or quarrion, is a species of small- to medium-sized parrot belonging to the cockatoo family (Cacatuidae), of which it is the smallest member. Native to Australia, it is the sole member of the genus Nymphicus.
Cockatiels are widely recognized for their expressive crests, long tail feathers, and sociable, playful nature, and their strong affinity for human interaction has made them among the most commonly kept companion parrots worldwide and one of the five most popular pet bird species; an estimated 4.8 million US households keep them. However, insufficient knowledge of their care contributes to one of the highest surrender rates among pet bird species.
Proper care requires regular social interaction with owners, as well as a suitable nutritionally appropriate diet, toy-based enrichment, annual veterinary check-ups and prompt attention when signs of illness or respiratory issues appear, perches of varying diameters, UV exposure, and about two hours of daily out-of-cage time. Due to many owners' unfamiliarity with these requirements, many cockatiels suffer chronic malnutrition and behavioral problems and are often relinquished to shelters within approximately 1.5 years of adoption.
The cockatiel is the only member of the genus Nymphicus. It was previously unclear whether the cockatiel is a crested parakeet or small cockatoo; however, more recent molecular studies have assigned it to its own subfamily, Nymphicinae. It is, therefore, now classified as the smallest subfamily of the Cacatuidae (cockatoo family). Cockatiels are native to Australia, favouring the Australian wetlands, scrublands, and bushlands. There are many different mutations of this bird. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cockatiel sighting in São Paulo on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 319th most-seen of the 353 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cockatiel in São Paulo on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Cockatiel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 11 cities where we can rate Cockatiel sightings, São Paulo ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Mashhad (Iran, under 5%), Santiago (Chile, under 5%) and Jerusalem (Israel, under 5%).
Same family: Psittacidae
The closest relatives of the Cockatiel that you can see in São Paulo (family Psittacidae, New World and African Parrots) are Plain Parakeet (about 80%), White-eyed Parakeet (about 40%) and Blue-fronted Parrot (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cockatiel is recorded against all the birds logged in São Paulo (8 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
