Palm Cockatoos repeatedly utter a monosyllabic whistle while moving from the congregation area to the feeding ground. Chicks when begging for food make a harsh guttural sound. Due to the pumping action its head makes, the sound is intermittent. This is a sound made by Palm Cockatoos in captivity. The bird utters a disyllabic growl and stomps its foot. This is a display of threat. This display goes with the contact call. The bird, with its crest partially raised, makes the first note of the contact call. After Palm Cockatoo which it spreads its wings, raises its tail and crest completely and lunges forward. The courtship display of Palm Cockatoos is elaborate. The male spreads his wings, raises his crest, the color of his cheek patches deepen and he makes excited sounds as he approaches the female. If an intruder approaches the nest, the Palm Cockatoo raises its crest and advances towards the intruder. It will then growl and stomp its feet. Males fight the intruder with their feet while the female stands close by and screeches. This display is seen only when it rains or it is about to rain. The Palm Cockatoo stretches it wings and tail and hangs upside down from a branch.

The red cheek patch deepens in intensity when Palm Cockatoos are excited or agitated. When Palm Cockatoos are stressed, they stomp their feet against a perch. Palm Cockatoos love to drum. They drum on almost anything. In the wild they are often seen sitting on a hollow trunk beating it with a stick or nut. Palm Cockatoos are relatively big birds and very active. Unless they have sufficient space to fly about and indulge in their other interests, they can become bored and distressed. Aviaries of several sizes have been suggested. Aviaries of 6 feet (1.8 m) x10 feet Palm Cockatoo (3 m) x 5 feet (1.5 m) and 8 feet (2.4 m) x 12 (3.6 m) x 8 feet (2.7 m) have both been suggested. When kept in an aviary that is sufficiently big, the birds are healthier and display their entire repertoire of behavior. Although some breeders have been able to get the birds to reproduce in an aviary 4 feet (1.2 m) x 8 (2.4 m) x 4 (1.2 m) in size, it's the bigger the better for Palm Cockatoos. The size of the aviary has a direct impact on their temperament and breeding success. So, choose carefully. In places where it is likely for temperatures to go below zero, an indoor cage with provision for heating should be provided. If, however, such low temperatures normally last for no more than a day, wind breakers and heating lamps inside the aviary should do fine. In places where temperatures can shoot up and make it unbearably hot, provide a covered location inside the aviary where the birds can get away from the heat. Misters and bird Temperature Palm Cockatoo baths may also be a good idea. |
