The cockatiel, Nymphicus hollandicus, is a charming and sociable bird, the only member of its genus and the smallest of the cockatoo family. Recognizable by its expressive crest, which indicates its emotional state, the cockatiel is a medium-sized parrot with a compact body and a long tail that makes up about half of its total length. Males typically boast a bright yellow face and a vibrant orange cheek patch, while females have a more subdued color palette.
When observing a cockatiel, look for the distinctive erectile crest that reflects the bird's mood. A startled or excited cockatiel will have a vertical crest, while a relaxed individual will show a gently oblique crest. The male's face turns a brilliant yellow after the first molt, and the orange cheek patch intensifies. Females retain their horizontal barring on the tail and a less vivid cheek patch.
Cockatiels are native to the Australian continent, where they thrive in wetlands, scrublands, and bushlands. They prefer environments close to water sources and are adept at adapting to various Australian landscapes.
Endemic to Australia, cockatiels are nomadic, moving to areas where food and water are readily available. They are commonly found in arid or semi-arid regions but are absent from the most fertile and desert extremes of the country.
Cockatiels are known for their gregarious nature, often seen in pairs or small flocks. They can become very vocal, mimicking human speech and household sounds. Males are particularly adept at learning and producing a variety of calls.
The cockatiel's vocalizations are less raucous than other parrots, with the ability to mimic human words and melodies. They can be taught to sing specific tunes and often repeat sounds from their environment.
Breeding is influenced by rainfall, with cockatiels nesting in tree hollows. The female lays 4-7 eggs, incubating them for about 17-23 days. Chicks fledge at 5 weeks, and cockatiels can reproduce by the end of their first year.
The cockatiel is unique within its genus, but its size and crest may cause it to be confused with small cockatoos. However, its long tail feathers and specific color patterns are distinguishing features.
Cockatiels in the wild primarily consume seeds from various native plants, including Acacia, wheat, sunflower, and Sorghum. They have also been known to feed on cultivated crops, much to the dismay of local farmers.
The cockatiel is listed as Least Concern by the IUCN, indicating a stable population without significant threats to its survival.
