Arrived at our destination, we built a but and prepared for a stay of some days--I to shoot and skin "Maleos", and Mr. Goldmann and the Major to hunt wild pigs, Babirusa, and Sapi-utan. The place is situated in the large bay between the islands of Limbe and Banca, and consists of steep beach more than a mile in length, of deep loose and coarse black volcanic sand (or rather gravel), very fatiguing to walk over. It is bounded at each extremity by a small river with hilly ground beyond, while the forest behind the beach itself is tolerably level and its growth stunted. We probably have here an ancient lava stream from the Klabat volcano, which has flowed down a valley into the sea, and the decomposition of which has formed the loose black sand. In confirmation of this view, it may be mentioned that the beaches beyond the small rivers in both directions are of white sand.
It is in this loose, hot, black sand that those singular birds, the "Maleos" deposit their eggs. In the months of August and September, when there is little or no rain, they come down in pairs from the interior to this or to one or two other favourite spots, and scratch holes three or four feet deep, just above high-water mark, where the female deposits a single large egg, which she covers over with about a foot of sand--and then returns to the forest. At the end of ten or twelve days she comes again to the same spot to lay another egg, and each female bird is supposed to lay six or eight eggs during the season. The male assists the female in ****** the hole, coming down and returning with her. The appearance of the bird when walking on the beach is very handsome. The glossy black and rosy white of the plumage, the helmeted head and elevated tail, like that of the common fowl, give a striking character, which their stately and somewhat sedate walk renders still more remarkable. There is hardly any difference between the ***es, except that the casque or bonnet at the back of the head and the tubercles at the nostrils are a little larger, and the beautiful rosy salmon colour a little deeper in the male bird; but the difference is so slight that it is not always possible to tell a male from a female without dissection. They run quickly, but when shot at or suddenly disturbed, take wing with a heavy noisy flight to some neighbouring tree, where they settle on a low branch; and, they probably roost at night in a similar situation. Many birds lay in the same hole, for a dozen eggs are often found together; and these are so large that it is not possible for the body of the bird to contain more than one fully-developed egg at the same time. In all the female birds which I shot, none of the eggs besides the one large one exceeded the size of peas, and there were only eight or nine of these, which is probably the extreme number a bird can lay in one season.
Every year the natives come for fifty miles round to obtain these eggs, which are esteemed as a great delicacy, and when quite fresh, are indeed delicious. They are richer than hens' eggs and of a finer favour, and each one completely fills an ordinary teacup, and forms with bread or rice a very good meal. The colour of the shell is a pale brick red, or very rarely pure white. They are elongate and very slightly smaller at one end, from four to four and a half inches long by two and a quarter or two and a half wide.
After the eggs are deposited in the sand, they are no further cared for by the mother. The young birds, upon breaking the shell, work their way up through the sand and run off at once to the forest; and I was assured by Mr. Duivenboden of Ternate, that they can fly the very day they are hatched. He had taken some eggs on board his schooner which hatched during the night, and in the morning the little birds flew readily across the cabin.
Considering the great distances the birds come to deposit the eggs in a proper situation (often ten or fifteen miles) it seems extraordinary that they should take no further care of them. It is, however, quite certain that they neither do nor can watch them. The eggs being deposited by a number of hens in succession in the same hole, would render it impossible for each to distinguish its own; and the food necessary for such large birds (consisting entirely of fallen fruits) can only be obtained by roaming over an extensive district, so that if the numbers of birds which come down to this single beach in the breeding season, amounting to many hundreds, were obliged to remain in the vicinity, many would perish of hunger.
In the structure of the feet of this bird, we may detect a cause for its departing from the habits of its nearest allies, the Megapodii and Talegalli, which heap up earth, leaves, stones, and sticks into a huge mound, in which they bury their eggs. The feet of the Maleo are not nearly so large or strong in proportion as in these birds, while its claws are short and straight instead of being long and much curved. The toes are, however, strongly webbed at the base, forming a broad powerful foot, which, with the rather long leg, is well adapted to scratch away the loose sand (which flies up in a perfect shower when the birds are at work), but which could not without much labour accumulate the heaps of miscellaneous rubbish, which the large grasping feet of the Megapodius bring together with ease.
