( Juniper and Parr, 1998 Lantermann, et al., 2000)Ĭacatua alba can live over 40 years in captivity and 30 years in the wild. Once a chick is able to care for itself, the group of three rejoins the rest of the flock. Chicks learn to fly at three months of age but are still dependent on the parents for another two to three weeks. Both parents are involved in caring for young, although females play a larger role. Cacatua alba chicks are born altrical and are completely dependent upon their parents. If it is malformed or unhealthy, they raise the second chick. ![]() If the first chick to hatch is healthy, they care for that one. Typically, the parents raise only one of the chicks. The male and the female share the responsibility of incubating the eggs. Range age at sexual or reproductive maturity (male) 5 to 6 years.Range age at sexual or reproductive maturity (female) 5 to 6 years.Range time to independence 3.5 to 4 months.Breeding season Breeding occurs when vegetation growth is at its peak, usually between December and March.Breeding interval White Cockatoos breed once yearly.gonochoric/gonochoristic/dioecious (sexes separate). ![]() ( "Threatened birds of Asia: the BirdLife International Red Data Book", 2001 Lantermann, et al., 2000) White cockatoos reach sexual maturity in six years. They learn to fly at three months of age but are still dependent on the parents for another two to three weeks. The male and the female share the responsibility of incubating the eggs until they hatch incubation usually lasts 30 days. They usually lay two eggs, occasionally three. They generally choose nesting holes in only the largest trees, and nest between 5 to 30 meters above ground. Pairs leave their group and find a nesting spot in a tree. They begin breeding when plant growth has reached its peak (usually between December and March). In the absence of a mate, white cockatoos in captivity will bond to a caretaker as if that person were its mate. They can slip into a deep depression if removed from their partner. Mates form a close bond with one another and are monogamous, with pair-bonds lasting throughout their lives. Adults that have previously mated successfully have a much shorter courtship ritual, and the female often approaches the male. After some time, the male mounts the female and they mate through the joining of the cloaca. This serves to strengthen the bond between the two birds. They then scratch each other around the head and tail. The female avoids him at first, but eventually permits him to come near her. It begins with the male showing off his body by ruffling his feathers, spreading his tail feathers, extending his wings, and erecting his crest. Range wingspan 25 to 31 cm 9.84 to 12.20 inĬourtship behavior in C.( Arndt and Pittman, 2003 Juniper and Parr, 1998) Females usually have a smaller head and beak than males.Ĭacatua alba weighs 500 to 630 g and is 46 cm long, on average. ![]() Both sexes have a pale blue eye-ring, but males have a dark brown iris while females have a reddish iris. Sexual dimorphism occurs in the eye coloration of C. It is often referred to as the "umbrella cockatoo" because of its broad, backward-bending crest. It has yellowish coloration on the underside of its wings and tail.
