Segni di campo chiave

• Crest. Look for the prominent, bright sulphur-yellow crest that can be raised or lowered. This is the most definitive field mark.
• Plumage Color. Observe the overall pure white body plumage. Note the pale yellow wash on the underside of the wings and tail, visible in flight.
• Size and Shape. Identify its large size and robust build, typical of a cockatoo, with a strong, hooked beak.
• Vocalizations. Listen for its very loud, harsh, screeching calls, which are highly characteristic and often heard before the bird is seen.
• Eye Color (for sexing). If close enough, observe eye color: dark brown/black for males, reddish-brown for females.
