Cockatiels (Nymphicus hollandicus) are native only to Australia where they are found largely in arid or semi-arid country, but always near water. Largely nomadic, the species will move to where food and water is available They are typically seen in pairs or small flocks.
Sometimes hundreds will flock around a single such body of water. To
farmers' dismay, they often eat cultivated crops. They are absent from
the most fertile southwest and southeast corners of the country, the
deepest Western Australia deserts, and Cape York Peninsula. They are the only Cockatoo species which can sometimes reproduce in the end of their first year. Their average lifespan is 15-20 years with some pet cockatiels living to 30-35 years.
