Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

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.
