The sombre, slow-flying Black Cockatoo is the largest of all Cockatoos. It is seen fairly often in small companies, especially on wattles and eucalypts, the wood of which it tears to pieces with its powerful bill to get the insect larvæ feeding there. It is a valuable forest-saving bird. The Glossy or Leach Black Cockatoo is named after Dr. Leach, who did a great amount of work on Australian animals about 100 years ago. It is a rare bird, and may readily be distinguished by its smaller size and more glossy plumage. The peculiar gray Gang-gang Cockatoos are common in parts of the forest country. The male is easily recognized by his red head and crest. I occasionally see these interesting birds in the big eucalypt forests of Gippsland. I was surprised to discover that, in South Gippsland, it is generally called the Galah, a name which belongs to quite a different bird (194). The screeching, fussy White Cockatoo, with its delicate sulphur crest, is well known. Many country dwellers enjoy the privilege of often seeing these snowy-white birds almost covering a dead tree. They are favorites as pets, and live to a good old age. They render good service at times by digging up and eating grasshoppers' eggs, though they do damage to maize and other crops. As they post sentinels, they are difficult birds to approach. The Pink Cockatoo (Major Mitchell) is unfortunately becoming rare. It was fairly common when I taught in a Mallee school, near where Hopetoun now is. It has been described as "quite the most beautiful of all the Cockatoos, being a harmony of delicate rose-pink and white, with a handsome crest of acuminate feathers barred in crimson, yellow, and white." It does not take kindly to captivity. It nested in the smaller "spouts" of the green "box-trees" in the "box-flats" and swamps about the Goyura School, south of Lake Corrong. What is more glorious than a mob of Rose-breasted Cockatoos (Galahs), 500 strong, airing their beauties and graces as they take a constitutional before retiring for the night? Probably no other kind of bird shows better company-flying than Galahs; now one sheet of a delicate gray lavender, and the next instant a flash of brilliant salmon-pink, as the whole company turns and wheels, obedient to some command or signal unperceived by us; again, the sun lights up the pale-pink crests and gray backs, as they turn once more and wheel, screeching, to continue their evolutions further afield. It is a sight that lingers in the memory. They are charming pets, and some talk well. Their beauty adds charm to our almost perfectly level great inland plains. The delicately-colored and friendly Cockatoo Parrot, with its immovable crest, takes a sub-family to itself. It migrates from the North, and, in a dry year, may even reach the South Coast. In 1908 some of these birds reached Colac, in Southern Victoria. They are favorite aviary birds, and thousands have been exported.
