💡 Interesting Facts

1

Raucous Flocks: Sulphur-crested cockatoos’ screeches reach 120 decibels in Royal National Park, their yellow crests signaling 50-bird flocks. Their millions-strong population, consuming 200 grams of seeds daily, faces pet trade losses, with 1,000 captured yearly.

2

Clever Mimics: In Dandenong Ranges, they mimic human speech, cracking nuts with 300 psi beaks, their intelligence endearing them in Cairns Esplanade. Conservation protects their hollows, ensuring survival despite crop conflicts, with females laying 20 eggs over a lifetime.
