The Wide-Awake Fair, of Ascension Island, is a famous annual event in natural history. A similar scene has been described by Mr. A. W. Milligan, the well-known West Australian ornithologist, on the Houtman Abrolhos Island, west of Western Australia. Here acres of the ground were covered by birds sitting on their nests. The question is, does each find its own nest when it returns to sit? Mr. Milligan settled this in the affirmative by tying a piece of string to a sitting bird and then letting it take flight. It found its own egg, and resumed its work. It is noteworthy that no two of the million eggs are similarly marked, and this puzzling variation in marking probably assists each bird to recognize its own egg. One of the daintiest of these birds is the Fairy Tern, which was common on Mud Island while the 1909 Summer School was being held. Obedient to the call of the mother bird, which hovered threateningly overhead, the mottled and striped young one squatted on the shelly sand beach while bird-lovers hunted around for the material for a photograph. At length the dark eye revealed the beautifully-protected young bird. As the camera was being fixed, a different call from the mother caused the young one to run away. Three or four naturalists tried to catch the active little bird, which stopped for a moment and disgorged two whole small fish, with which its mother had evidently but recently fed it. Eventually a good picture was obtained. These Terns nest singly, though others nest in large companies. They obtain fish by diving into the sea. It was interesting, on a Nature-study excursion, to watch the Crested Terns diving frequently into the sea above a shoal of small fish at Sandringham. We found the Noddies breeding in thousands on Mast Head Island, in the Capricorn Group. They built a small platform of leaves, or seaweed, high or low, on every possible nesting site on the great _Pisonia_ trees. In fact, there is an interesting kind of partnership between the bird and the tree. The fruits of the _Pisonia_ have bands of sticky glands, which adhere to the plumage of the birds. After a time the fruits fall off, possibly on another island, and so this interesting tree is spread throughout these small coral sandbanks and islets. The birds are sometimes so loaded and clogged with these fruits that they are incapable of flight. Surely here is a wonderful partnership between the tree-frequenting Noddy and the forest tree that provides shelter and nesting places for it. It is, indeed, a marvellous method of seed dispersal.
