The large Black Cormorant is the common Black Cormorant of Britain. It has a very extensive range over North America, Greenland, Europe, Africa, Asia, and Australia. The little Black Cormorant is found in Australia, from the Moluccas to Borneo, and in New Zealand. Indeed, New Zealand is the stronghold of Cormorants, as it possesses many species. The White-breasted and Pied Cormorants are so closely similar that possibly they will yet prove to be one species. Each is glistening white below, and jet black above. The bill is said to be longer in the Pied Cormorant, and the patch of naked skin near the eye is yellow, whereas, in the White-breasted Cormorant, this patch is said to be blackish or purplish. The Little Cormorant is also black and white. Its throat and upper chest are yellow. Mr. Mattingley, C.M.Z.S., and others claim that the Cormorant, by feeding its young on yabbies, which, they say, prey on fish eggs, saves many more fish in the young stage than it ever eats in the adult stage, and hence it is really "a friend" of the anglers and fish. One thing is certain--fish were formerly much more abundant, and so were Cormorants. Anglers, collect evidence, and balance good with evil. Cormorants have a long, narrow bill, with a strongly-hooked tip. They are such expert fishers that in China they are much used to catch fish. Some will probably be surprised to learn that this custom formerly held in England, for the "Master of the Cormorants" was once one of the officers of the Royal household. Some Cormorants nest in company in the Murray swamps, while others retire to a rocky island, such as Storehouse Island, east of Flinders Island, to breed. These birds are expert swimmers and divers, so that one of the common names for them is "Diver," but the true Divers, as already pointed out, are Northern Hemisphere birds, and are placed in Family 25. The Darter, or Snake Bird, is practically identical with the Water-Turkey of the United States. Sometimes, when alarmed, it submerges its body, leaving the head and neck exposed. It swims rapidly in this position. Four of these birds are known, and they are spread over America, Africa, Madagascar, Southern Asia, New Guinea, Australia, and New Zealand. The Darter was frequently seen on a recent trip to Enoggera Reservoir, the storage basin for Brisbane. The long, stiletto-like bill is used to impale its prey, while the flexible neck assists the spearing operation.
