Nymphicus hollandicus, commonly known as the Cockatiel, is native to the arid regions of Australia. These small parrots are recognized for their distinctive crests, expressive plumage, and vibrant cheek patches. They are highly social, intelligent, and known for their whistling ability and affectionate nature, often forming strong bonds with humans.

Nymphicus hollandicus, commonly known as the Cockatiel, is native to Australia. It is found across most of the Australian mainland, particularly in arid or semi-arid regions, and is prevalent in the interior regions of the continent.

The Cockatiel primarily inhabits open environments such as grasslands, scrublands, and bushlands. It thrives in areas with access to water sources, as it often congregates around rivers and lakes. The climate in these regions can be quite variable, ranging from hot and dry to more temperate conditions, depending on the season and specific location.

Cockatiels are ground-nesting birds that feed on a variety of seeds, fruits, and insects. They are well adapted to the open, dry landscapes of Australia's interior and can often be found in large flocks. Their ecological niche involves playing a role in seed dispersion due to their feeding habits, and they are an integral part of the ecosystem, providing prey for larger birds and mammals.
