“This incident might not have been worth mentioning, had it not been for the extraordinary agreement in point of size of the bird”—with his deductions from the bones. “Here are the bones which will satisfy you that such a bird has been in existence; and there is said to be the living bird, the supposed size of which, given by an independent witness, precisely agrees.” In spite, however, of several tales of this kind, it is almost certain that these birds are now quite extinct.

The leg-bones sent to London greatly exceeded in bulk those of the largest horse. The leg-bone of a tall man is about 1 ft. 4 in. in length, and the thigh of O’Brien, the Irish giant, whose skeleton, eight feet high, is mounted in the Museum of the Royal College of Surgeons, is not quite two feet. But some of the leg-bones (tibiæ) of Moa-birds measure as much as 39 inches.
In 1846 and 1847 Mr. Walter Mantell, eldest son of Dr. Mantell, who had resided several years in New Zealand, explored every known locality within his reach in the North Island. He also went into the interior of the country and lived among the natives for the purpose of collecting specimens, and of ascertaining whether any of these gigantic birds were still in existence; resolving, if there appeared to be the least chance of success, to penetrate into the unfrequented regions, and obtain a live Moa. The information gathered from the natives offered no encouragement to follow up the pursuit, but tended to confirm the idea that this race of colossal bipeds was extinct. He succeeded, however, in obtaining a most interesting collection of the bones of Moa-birds, belonging to birds of various species and genera, differing considerably in size. This collection was purchased by the trustees of the British Museum for £200. Another collection was made by Mr. Percy Earle from a submerged swamp, visible only at low water, situated on the south-eastern shore of the Middle Island. This collection also was purchased by the trustees for the sum of £130. Mr. Walter Mantell, who described this locality, near Waikouaiti, seventeen miles north of Otago, thinks it was originally a swamp or morass, in which the New Zealand flax once grew luxuriantly. The appearance and position of the bones are similar to those of the quadrupeds embedded in peat-bogs, as, for instance, the great Irish elk (see next chapter). They have acquired a rich umber colour, and their texture is firm and tough. They still contain a large proportion of animal matter. Unfortunately, even when Mr. Walter Mantell visited this spot, the bed containing the bones was rapidly diminishing from the inroads of the sea, and perhaps by this time is entirely washed away. Mr. W. Mantell, however, obtained fine specimens and feet of a large Moa-bird (Dinornis) in an upright position; and there seems to be little doubt that the unfortunate bird was mired in the swamp, and perished on the spot.
The bones which he obtained from the North Island presented a different appearance, being light and porous, and of a delicate fawn-colour. They were embedded in loose volcanic sand. Though perfect, they were as soft and plastic as putty, and required most careful handling. They were dug out with great care, and exposed to the air and sun to dry before they could be packed up and removed.
The natives were a great source of trouble to him, for as soon as they caught sight of his operations they came down in swarms—men, women, and children, trampling on the bones he had laid out to dry, and seizing on every morsel they could get. The reason of this was that their cupidity and avarice had been excited by the large rewards given by Europeans in search of these treasures. Mixed with the bones he found fragments of shells, and sometimes portions of the windpipe, or trachea.
One portion of an egg which he found was large enough to enable him to calculate the size of the egg when complete. “As a rough guess, I may say that a common hat would have served as an egg-cup for it: what a loss for the breakfast-table! And if many native traditions are worthy of credit, the ladies have cause to mourn the extinction of the Moa: the long feathers of its crest were by their remote ancestors prized above all other ornaments; those of the White Crane, which now bear the highest value, were mere pigeon’s feathers in comparison.”
The total number of species of Moa once inhabiting New Zealand was probably at least fifteen, and, judging from the enormous accumulations of their bones found in some districts, they must have been extremely common, and probably went about in flocks. “Birds of a feather flock together” (proverb).
It is justly concluded, both from the vast number of bones discovered, and from the fact of their great diversity in size and other features, that they must have had the country pretty much to themselves; or, in other words, they enjoyed immunity from the attacks of carnivorous quadrupeds. In whatever way the Moas originated in New Zealand, it is evident that the land was a favourable one, for they multiplied enormously, and spread from one end to the other. Not only was the number of individuals very large, but they belonged (according to Mr. F.W. Hutton) to no less than seven genera, containing twenty-five different species, a remarkable fact which is unparalleled in any other part of the world. The species described by Professor Owen in his great work,[75] vary in size from 3 ft. to 12 or even 14 ft. in height, and differ greatly in their forms, some being tall and slender, and probably swift-footed like the ostrich, whilst others were short and had stout limbs, such as Dinornis elephantopus ([Fig. 56]), which was undoubtedly a bird of great strength, but very heavy-footed. Dinornis crassus also had stout limbs. (See [Plate XXIII.])
