![]() The yellow-tailed black cockatoo is found in temperate forests and forested areas across south and central eastern Queensland to southeastern South Australia, including a very small population persisting in the Eyre Peninsula. The whiteae is found south of Victoria to the East of South Australia and is smaller in size. Their loud, wailing calls carry for long distances. In flight, yellow-tailed black cockatoos flap deeply and slowly, with a peculiar heavy fluid motion. The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. The body feathers are edged with yellow giving a scalloped appearance. Its plumage is mostly brownish black and it has prominent yellow cheek patches and a yellow tail band. It has a short crest on the top of its head. Wood-boring grubs, eucalypt and various pine seeds predominate.The yellow-tailed black cockatoo ( Zanda funerea) is a large cockatoo native to the south-east of Australia measuring 55–65 cm (22–26 in) in length. Tall eucalypt forests, pine (exotic) plantations and heaths. Rockhampton (Qld), south to Tasmania and west to South Australia. Some authorities and aviculturalists generally regard this as a separate and distinct species. The description for this subspecies is distinctive in that it has white panels in the tail. Infected birds will infect their offspring simply by feeding them as there is always chances of contact with faeces in the nest and during feeding of the young.Ĭalytorhynchus funereus latirostris occurs in the west of the distribution. The best course of action for affected birds is to destroy them as there is no cure. It is advisable to test birds suspected to have this condition. Similarly, the beak is also affected and becomes fragile and does not repair itself. Essentially, it results in poor feather growth and feathers which don’t replace themselves when they fall out. This is an incurable disease which is transmitted through feaces. These are relatively easily dealt with however simply by maintaining a high standard of hygiene.Īnother problem encountered in this species is Psittacine beak and feather disease. Similarly, fungal infections may become a problem. Intestinal worms are a common problem in species which spend considerable time on the ground. Similarly, the frame should be constructed of steel to avoid the birds chewing the structure away. The wire should be of a heavy duty grade, as cockatoos easily chew holes in lighter grade wire. These should be somewhere in the vicinity of 2m wide x 2m high x 5 or 6m long so as to provide amply flight space and to accommodate nesting logs etc. However, these birds always fare better (and look more spectacular) in larger aviaries. Pairs can be kept in a slightly larger cage. There are exceptions to this however with some birds having bred at 2-3 years of age.Īs a minimum, a single bird may be housed in such a cage provided it measures at least 800mm x 600mm x 1200mm (approximately). These birds are sexually mature at about 4 years of age. During this procedure, he utters a distinct clucking sound. In this posture, they approach the female and strut along the perch making flicking and bowing movements with the head. ![]() ![]() Males stretch to their full height, raise the crest and fan the tail. Once fledged, the young remains dependant on the parents for an indefinite period. Fledging usually occurs at about 70 days. The preferred nesting material is a mixture of wood shavings and dirt or peat moss.Ģ white oval eggs laid at interval of between 2 and 7 days. Logs should be suspended vertically or may be placed (upright) on the aviary floor. Entrances should be at the top or on the side near the top. In captivity yellow-tails usually prefer nesting logs of 1m in height with an internal diameter of about 40cm and an entrance of at least 20cm diameter. Both parents subsequently care for the young. Only the female incubates the eggs for the first 20 days. Both the male and female prepare the nest. ![]() Internal diameter is about 30-40 cm and depths of 60cm to 2m have been recorded. The usual nesting site is a tree cavity in a eucalypt at heights ranging from 10 to 30m or more above ground. It is strongly arboeal in the east, but western birds are frequently found foraging on the ground.įrom October to May in the east, July to December in the west of its distribution. Immatures resemble females with grey beaks. Adult females have white beaks, a (less pronounced) dark grey periopthalmic ring and bright yellow cheek patches. Males have black or dark grey beaks, a fleshy coloured periopthalmic ring and dull yellow cheek patches. Very large cockatoo with dull black body plumage narrowly scalloped in dull yellow, yellow cheek patches and large yellow tail panels which have black mottling.
