The Brush-tongued Parrots, or "Lorikeets," are a purely Australian family. Some of these are very common at times in flowering eucalypts, even in the public gardens and streets. The Blue Mountain Parrot, very common at times, is a giant of the family. It has been described as a "noble bird, gorgeously apparelled." Its vernacular name of Blue-bellied Lorikeet has been altered to Blue Mountain Lorikeet. We found these birds nesting in the big sugar-gums bordering Warunda Creek, Eyre Peninsula. They keenly and noisily resented our curiosity, and screeched much as we tried to discover them amongst the green foliage. Though so gaudy, they were picked out with difficulty. This bird was very troublesome in my garden at Bengworden, near the Gippsland Lakes, where, when the apples were about the size of marbles, they tore them to pieces to get the developing "pips." In common with the other members of the family, they have a swift, direct flight, and screech much when flying. The "Green Keets," generally called "Green Leeks," which are so very numerous at times, are often accompanied by two other Lorikeets, the Little and Purple-crowned Lorikeets. These green birds hang, head down, among the eucalyptus leaves, and brush up the honey from the flowers with their brush tongue. They follow the flowering of the eucalypts from district to district, and since the eucalypts flower at irregular intervals, these birds are not so regular in their movements as Swifts, Snipe, Curlews, Cuckoos, and other migratory birds. For this reason the birds may be absent from a district for some years, and then suddenly appear again in great numbers. Cockatoos are almost confined to the Australian region. This includes the islands north-west of Australia out to Wallace's line, passing between Celebes and the Philippine Islands, Celebes and Borneo, and between the small islands of Lombok and Bali, east of Java. These islands, though but fifteen miles apart, "differ far more from each other in their birds and quadrupeds than do England and Japan. The birds of the one are extremely unlike those of the other." Another authority says that the faunas of Bali and Lombok are more unlike than those of South America and Africa. Bali has Woodpeckers, Barbets, Bulbuls, and Black and White Magpie-Robins, none of which is found in Lombok, where we find Screaming Cockatoos, Friar-birds, and other Honey-eaters, and the strange mound-building Megapodes and numerous other remarkable birds. This narrow strait is over 1000 fathoms in depth, and is probably one of the most ancient and most permanent dividing lines in the world. Instead of being united to Asia, it is probable that Australia has been more recently joined to New Zealand, South America, and South Africa. Only one Cockatoo transgresses Wallace's line to the west, and that is found in the Philippine Islands; evidently it has spread there from the adjacent part of the Australian region.
