Umbrella Cockatoo

About

The Umbrella Cockatoo, also known as the White Cockatoo, is a medium-sized, all-white parrot endemic to the islands of Indonesia. Renowned for its large, expressive crest that it raises when excited or alarmed, it is a highly intelligent and social bird.

Size & lifespan

Length

43-50 cm (17-20 in)

Wingspan

80-90 cm (31-35 in)

Weight

400-800 g (0.9-1.8 lbs)

Lifespan

40-60 years in the wild, up to 80 years in captivity

Diet

Herbivore (primarily granivorous and frugivorous)

Physical characteristics

Plumage

Entirely white plumage, with a pale yellow wash on the underside of the wings and tail feathers, visible during flight or when the wings are spread. The most striking feature is the large, erectile crest of white feathers on its head.

Beak shape

Large, powerful, dark grey to black beak, strongly curved for cracking nuts and seeds.

Eye color

Males typically have dark brown to black eyes; females often have reddish-brown eyes.

Leg color

Dark grey to black

Distinguishing features

The prominent, broad, umbrella-like crest that can be raised and lowered. The pale yellow wash on the underwings and undertail is a key field mark.

Juvenile appearance

Juveniles resemble adults but may have slightly duller plumage and a less developed crest. Their eyes are typically dark brown, similar to adult males, making sexing by eye color unreliable until maturity.

Seasonal changes

No significant seasonal plumage changes. Plumage remains consistently white throughout the year.

Sexual dimorphism

Subtle sexual dimorphism exists primarily in eye color (males dark brown/black, females reddish-brown), though this can be difficult to discern in the field. Females may also be slightly smaller on average.

How to identify

1. 1

   Plumage Color

   Look for an entirely white body plumage. Any strong pink or yellow coloration on the body or crest would indicate a different species.

2. 2

   Crest Shape and Color

   Observe the large, broad, all-white crest. When raised, it forms a distinctive umbrella-like shape. This is a key identifier distinguishing it from other white cockatoos with colored crests.

3. 3

   Underwing/Undertail Wash

   In flight or when wings are spread, look for a subtle, pale yellow wash on the underside of the wings and tail feathers. This is less prominent than in some other species but present.

4. 4

   Eye Color (Sexing)

   If close enough, note the eye color. Males typically have dark brown/black eyes, while females often have reddish-brown eyes. This is a useful, though not always definitive, indicator of sex.

5. 5

   Vocalizations

   Listen for their characteristic loud, piercing 'raah-ah' calls and various squawks and screeches. Their vocalizations are distinct from other cockatoo species.

Habitat & range

Biomes

Tropical and subtropical moist broadleaf forests, mangroves, and cultivated areas.

Geographic range

Endemic to the northern Moluccas (Maluku Utara) in Indonesia, specifically the islands of Halmahera, Bacan, Ternate, Tidore, Kasiruta, and Mandioli.

Elevation range

Primarily lowlands, from sea level up to approximately 900 meters (3,000 feet).

Preferred environments

Prefers primary and secondary lowland forests, forest edges, clearings, and sometimes agricultural lands where food is abundant. They are often found near rivers or other water sources.

Behavior

Activity time

Diurnal, most active during the early morning and late afternoon, foraging and vocalizing.

Feeding habits

Feeds on a variety of seeds, nuts, fruits, berries, flowers, and insects (larvae). They use their powerful beaks to crack open hard shells and extract food. They often forage in the canopy but will descend to the ground.

Social behavior

Highly social birds, typically found in pairs or small family groups. They can form larger flocks at communal roosting sites or abundant food sources. They are known for their intelligence and strong pair bonds.

Flight pattern

Strong, direct flight with relatively shallow wing beats. They are often seen flying in pairs or small groups, especially at dawn and dusk when moving to and from roosting sites.

Migration pattern

Resident; no significant migratory patterns. They may undertake local movements in search of food or suitable nesting sites.

Territoriality

Pairs defend their nesting territory during the breeding season. Outside of breeding, they are less territorial, especially when foraging in larger flocks.

Breeding & reproduction

Breeding season

Typically May to September, though can vary depending on local conditions and food availability.

Nesting habits

Nests are constructed in tree hollows, often high up in large, mature trees. Both parents participate in preparing the nest cavity.

Clutch size

1-3 eggs, most commonly 2.

Egg description

Typically 2-3 white, oval eggs.

Incubation period

Approximately 28-30 days, incubated by both parents.

Fledging period

Chicks fledge (leave the nest) around 10-11 weeks after hatching. They remain dependent on their parents for several weeks to months after fledging.

Parental care

Both parents share incubation duties and care for the chicks, feeding them regurgitated food until they are independent.

Where to find

Field tips

1. Listen for Calls. Their loud, distinctive calls are often heard before the birds are seen. Listen for their piercing 'raah-ah' calls, especially at dawn and dusk.
2. Look for Flocks. While often seen in pairs, they can gather in larger flocks at communal roosting sites or abundant food sources. Scan the canopy for groups of white birds.
3. Observe Roosting Sites. They often use the same large trees for roosting. Observing these sites at sunrise or sunset can provide good viewing opportunities as they leave or return.
4. Check Fruit Trees. Focus on areas with fruiting trees or cultivated fields, as these are preferred foraging locations.
