Lyall tells us that the holes he saw had two openings, and the trees above them were for some distance hollow. The Kakapo, he says, was not visible by day, except when driven from its retreat; and he was never able to find it but with the help of dogs. When these birds were more plentiful, the natives used to catch them at night by torch-light. There is a breed of half-wild dogs in the northern part of this island continually hunting the Kakapos, which, indeed, they have almost exterminated. It is said that the spread of these dogs is arrested by a river; but it is to be feared that so soon as they succeed in crossing that barrier, the total extinction of these birds will ensue; for although they use their beak and claws very energetically, and can make a powerful resistance, still, sooner or later, they must succumb to their four-footed enemy, and ultimately share the fate of the MOA, the DRONTE, and other species recently become extinct. "The Maoris assure me," says Haast, "that the Kakapo is brave, and often confronts the dogs with success; but this cannot be credited if their dogs are worth anything, for mine never had any serious battle with it. At first, the dog was attacked both with beak and claws, but it soon learnt to conquer its game by biting it through the back." An idea was formerly entertained that the Kakapos were nocturnal in their habits, but our observations lead us to believe that this is not exactly the case. We generally heard their voices about an hour after sunset, in places which were rendered dark and obscured by thick foliage, and they then began to sweep about, attracted by the light. We, however, twice saw these birds during the day feeding upon the ground, and strictly upon their guard against approaching danger. On the first occasion, about noon on a cloudy day, we were returning through an open wood from the western coast, and saw the Kakapo sitting upon an uprooted tree, not far from the Haast river; as we approached, it quickly disappeared, but was caught by the dogs. The second time, on a clear day, as we entered a deep ravine, we saw one of these birds perched ten feet high upon a fuchsia-tree, the berries of which it was eating. As soon as it saw us, it fell, as though shot, to the earth, and disappeared beneath the surrounding blocks of stone. The most astonishing thing was, that the bird made no use of its wings; indeed, did not even open them to break its fall. In order to ascertain whether it would either fly or flutter, we followed, and having with us a Kakapo that had been taken uninjured by the dogs, we set it free upon a large, open, gravelly spot, where there was plenty of room to run away, if it wished to do so, or to raise itself into the air, even should it require a large space for that purpose. We were much surprised to find that it only ran to the nearest thicket, and that much faster than we could have thought possible from the structure of its toes and the bulk of its body.
