Where to find the

Umbrella Cockatoo

The umbrella cockatoo is a native of the Indonesian islands of Northern and Central Moluccas (aka Maluku Islands), specifically, the islands of Bacan, Kasiruta, Halmahera, Tidore, Ternate, and Mandioli. They inhabit wooded areas and are found in open woodland and forests, mangroves, swamps, and agricultural areas. They are especially common around the edges of clearings and rivers. Most of their time is spent in the tree canopy.

How the

Umbrella Cockatoo

lives

Umbrella cockatoos typically occur singly, in pairs or small groups, and sometimes in flocks numbering up to fifteen. They gather in the afternoon in groups of as many as fifty birds. Although these birds are social, aside from mating pairs, they usually do not establish close bonds with each other. They are diurnal birds and are typically sedentary, although some can be nomadic, wandering in search of food. White cockatoos communicate with their mates by means of a variety of noises and gestures. They scratch one another during mating rituals. They have been seen banging pieces of wood on logs and trees to warn other birds that their territory belongs to them. White cockatoos use loud vocalizations, sometimes for communication. They make a loud, grating scream or screech and they may hiss when alarmed.

GROUP NAME:  flock, company, pandemonium

Relationships

Umbrella cockatoos are monogamous, a mating pair staying together for life. In the mating season, males strut and fan their crests to attract a female. The mating season is usually from December to March. Pairs leave their flock to seek a place to nest in a tree. They typically build a nest in a hollow of a very large, tall tree. The female lays two eggs, sometimes three. Males and females share the incubating of the eggs, which usually lasts 30 days. The parents typically raise only one chick. If the first one that hatches is healthy, they raise that one. If the chick is unhealthy or malformed, they raise the second one. Chicks learn to fly when they are 3 months old but still depend on their parents for a further 2 to 3 weeks. When a chick is capable of caring for itself, the family rejoins the flock. White cockatoos are sexually mature within six years.

ECOLOGICAL NICHE

Umbrella cockatoos have an important role in dispersing seeds – which is important for the evolution and ecology of plants. Furthermore, their nests may be used by other animals during the non-breeding season.
