📖 1. Overview
The Cockatiel is a small crested parrot living in the open inland areas of Australia and is the second most popular pet bird after the Budgerigar.
🦴 2. Anatomy & Morphology
It is the smallest and slenderest of the cockatoos, and unusually for a crested parrot, its tail comes to a point. The tail is about 15 cm long, about half its body length, and spreads like a fan in flight to control altitude and balance.
🔍 3. Ecology & Behavior
Its long toes allow it to walk steadily on the ground, and it rotates dry seeds of grasses, shrubs, and trees with its tongue while husking them with its bill. Once paired, mates stay together all year round, moving in pairs or flocks of hundreds, and are especially fond of Acacia seeds.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
