Triton Cockatoo

Cacatua galerita triton New Guinea

Triton cockatoos are a subspecies of Cacatua galerita Along with the well known Greater sulphur crested cockatoo and Medium sulphur-crested cockatoos. Tritons are large white cockatoos with recurved yellow crests. The crest feathers lie flat on the top of the head with the tips curling upward. The only other color is yellow on the undersides of the wings. The crest feathers spread out and up when the crest is erect. They have blue-eye rings and a heavier beak than the Medium sulphur-crested cockatoo. The crest is heavier and fuller than other subspecies.

Triton cockatoos are found on the island of New Guinea (Papua New Guinea and Irian Jaya- Indonesia) and the west Papuan islands. They inhabit forests, especially mature canopy forests from the lowlands extending up to an elevation of 2,400 m (7,200 ft) in eastern Papua New Guinea. They also frequent cleared lands. They are most active in early morning and late afternoon. Wild cockatoos feed on fruits, nuts, seeds, berries and insects.

Length is 18 to 20 inches. Weight is 600 to 800 grams. Males are generally larger than females and have larger heads and beaks.

Tritons and other cockatoo species can be very long lived and a few individuals in zoos have lived up to 50-60 years. Precise data on life span of the average Triton cockatoo is poorly documented. Birds often succumb to disease or injury rather than living for their potential lifespan.

Breeding age can be as young as 3 years, however hand-reared birds may not begin breeding before they are 6 to 8 years old. Breeding life span is not precisely known but is possibly up to 30+ years.

Personality - Triton cockatoos are affectionate, playful and highly intelligent birds. They are excellent companion birds for those who want a charming, loving bird but are not quite as docile as Moluccans and Umbrellas. Tritons tend to be very demanding of attention and if they are deprived of attention can become very noisy and destructive or turn to plucking or self-mutilation behavior. Imprinted cockatoos may become possessive of their owners. This possessive behavior can lead to unpredictable or aggressive behavior towards other people especially as the bird reaches sexual maturity.

While Tritons will occasionally speak, they are not known for their ability to mimic. They are however very vocal and many birds loose their home due to loud screaming. This behavior is often learned when young birds hear the morning or afternoon screaming of another cockatoo.

Activities – Triton cockatoos are playful and inquisitive and they love to chew objects in their surroundings. They are very destructive if allow to perch on furniture. They should always be provided with toys, blocks of wood or branches that they can chew. In order to ensure safety companion cockatoos should not be allowed unsupervised freedom in the home as they often encounter toxins or dangerous items. Young cockatoos should be socialized to many people and exposed to a variety of situations such as new cages, toys, visits to the veterinarian, handling by friends, wing and nail clips, etc. to avoid fear of novel situations.

Dietary needs - Cockatoos should be fed a formulated (pelleted or extruded diet) as a basis for good nutrition. Kaytee Exact is an excellent choice for their staple diet. The diet should be supplemented with fresh fruits and vegetables daily to add variety and psychological enrichment. Feed approximately 1/3 cup of Kaytee exact and 1/3 cup of fresh fruits and vegetables daily. If the bird consumes all of it’s food give additional food as desired. Overfeeding leads to pickiness, wastage and throwing food. Treats such as seeds, nuts and table foods maybe given in small amounts especially as rewards for good behavior.

Special requirements - Triton cockatoos are very efficient in utilization of calories. Juvenile cockatoos are notoriously picky eaters and don’t seem to need much food to maintain themselves. Try to ensure that the food that they do eat is nutritious. Vitamin supplements are not needed for birds that are eating a formulated diet.

Grooming - Routine bathing or showering is vital to maintaining good plumage and skin condition. Birds can be misted and allowed to dry in a warm room or in the sun, or gently dried with a blow drier. Care should be taken not to clip the wing feathers excessively as cockatoos often fall and injure themselves. Clip only the primary flight feathers and only enough so the bird will glide to the floor.

Identification - All companion and breeding birds should be individually identified to assist in recovery if lost and assist in maintenance of medical and genealogical records. Many breeders apply closed legs bands when chicks are young. While they present a slight risk of entrapment closed bands are preferable to no identification, especially for breeding birds.
Microchips, which can be implanted into the muscle or under the skin, are a reliable means of identification but require electronic readers to verify identification. Tattoos may be used but often fade or become illegible with time. Foot prints may have some application in identification.

Sexing Most of the white cockatoos species can be sexed by eye color when mature, The eyes of a mature female Triton are red while the eyes of the male are dark brown or black. Juveniles of both sexes will have brown eyes. The sex of breeders should be confirmed by endoscopy (surgical sexing) of DNA sexing.

Housing - Triton cockatoos are very active and should be provided the largest cage that space and budget allows. Durable cage construction is very important because Tritons are very strong chewers and can easily break welds on poorly constructed cages. Many are also adept at opening cage latches. Locks or escape proof latches may be necessary on cages. The cage should be as large as possible but must allow at least enough room to fully spread the wings. Ideally the bird will have an outdoor cage as well to allow play time in the fresh-air and sunlight.

Breeding – Triton cockatoos breed well in captivity but are not as prolific or bred as commonly as Moluccan and Umbrellas. In North America Triton cockatoos breed predominantly in the winter and spring. Clutch size is typically 2 to 3 eggs. The breeding cage should be large enough to allow some limited flight between perches. One inch by one inch by 12 guage welded wire is a good choice for cage construction. A suggested size is 4 feet wide by 4 feet tall by 8 feet long suspended 4 feet above the ground or floor.

Nest Box - Double entrance boxes are often used to reduce the chance of the male trapping the female in the box. Large grand-father style wooden boxes can be used. Size should be approximately 18” x 18” x 24”. Metal barrels, plastic pickle barrels and garbage cans can be used, however the act of chewing a wooden nest box may stimulate reproductive behavior.

Incubation period is approximately 24-26 days. Chicks will usually fledge at approximately 12 to 14 weeks of age. Triton cockatoos are relatively easy to hand-rear. Most handrearing formulas can be used successfully, however if you are using a formula which is relatively high in fat, care must be taken not to overfeed the chick. Kaytee Exact regular handrearing diet is a good choice.

Aggression
Male cockatoos frequently become aggressive toward their mates. Fatal attacks may occur in which the male bird severely bites the face, wings, and legs of the female. Cage construction and management must take into consideration techniques to reduce mate aggression. Clipping the wings of the male prior to the breeding season will help the female to escape in case the male becomes aggressive. Aggressive behavior may occur in compatible breeding pairs.

When breeding cockatoos, noise and proximity to neighbors must be considered. If housed outdoors cockatoos often call at night especially during a full moon. In southern states outdoor caging must be protected from opossums to prevent exposure to the parasite Sarcocystis falcatula which can result in a fatal lung infection.

Common diseases and disorders

• Psittacine Beak and Feather Disease (Now rare in captive cockatoos)
• Proventricular dilation disease
• Feather-picking
• Self mutilation
• Juvenile chewing of flight feathers and tail
• Poor eating habits - picky eaters
• Bacterial and fungal infections
• Sarcocystis
• Mate aggression
• Toxicity, ingestion of metals
• Chlamydophilia (Chlamydia) infections (psittacosis or parrot fever)

Conservation Status - Triton cockatoos are listed on Appendix II on the Convention on International Trade in Endangered Species. Their wild population has declined due to habitat destruction and trade but they are locally common in much of their range. Future development and habitat destruction may have a major effect on their population.
