Sulphur-crested Cockatoo

One of the largest and most iconic cockatoos, sulphur-crested cockatoos inhabit forest and woodland across eastern Australia, New Guinea, and the Moluccas, and have been introduced to New Zealand. They are highly intelligent, long-lived (up to 70 years in captivity), highly social, and famously loud, with screaming calls audible over 1 km. They have become pest species in urban areas where they strip bark, chew timber, and damage crops, demonstrating remarkable adaptability to human-modified environments.
