 The breeding season varies according to latitude , taking place from April to July in Queensland , January to May in northern New South Wales , December to February in southern New South Wales , and October to February in Victoria , South Australia and Tasmania . The male yellow @-@ tailed black cockatoo courts by puffing up crest and spreading his tail feathers to display his yellow plumage . Softly growling , he approaches the female and bows three or four times to her . His eye ring may also flush a deeper pink . Nesting takes place in large vertical tree hollows of tall trees , generally eucalypts , which are either living or dead . Isolated trees are generally chosen , so birds can fly to and from them relatively unhindered . The same tree may be used for many years . A 1994 study of nesting sites in Eucalyptus regnans forest in the Strzelecki Ranges in eastern Victoria found the average age of trees used for hollows by the yellow @-@ tailed black cockatoo to be 228 years . The authors noted that the proposed 80 – 150 year rotation time for managed forests would impact on the numbers of suitable trees .
