In a second communication, made to the same society, by Dr. Bennett, in 1863, he speaks of another living specimen of this rare bird brought to Sidney by Mr. Williams. "It was," he says, "at first rather shy and wild, but afterwards became more tame, and manifested but little fear; this feeling was, however, occasionally exhibited by the utterance of rapid 'coos,' and by fluttering its wings. It is a stupid-looking bird, and has no particular attraction except in the anomalous and extraordinary form of the beak, which cannot fail to attract the attention of the most ordinary observers. The only sound it utters is a quick 'coo-coo-coo,' the beak being always open when the sounds are emitted. The bird was captured about five miles from Apia, in the Island of Upola; it is evident, therefore, that a few still remain there. It is, however, agreed by every one with whom I have conversed who has resided at the Navigators' Islands, that it is nearly extinct, both from being eaten by the natives, as well as owing to the attacks of cats, rats, and other vermin. Its food consisted at first of boiled yams, but it will eat bananas, apples, bread, and boiled potatoes." In a third paper, read by Dr. Bennett in 1864 at a meeting of the Zoological Society, he says:--"In the contour of the bill, the form and position of the nostrils, and several other characters, the Didunculus differs from any other living species yet known. Although a smaller bird, it approximates in all its characters to the extinct Dodo, and, like it, combines the characters of a rapacious bird with those of the harmless Pigeon. Although the mandibles are powerful, yet the beak is never used as an offensive weapon, for when the hand is placed in the cage, or the bird is seized for removal from one cage to another, it never attempts to bite, but, on the contrary, is so timid that, after fluttering about or running into a dark corner, it soon becomes subdued and is easily taken." Of a living pair purchased by Dr. Bennett, he says: "They would nibble into minute bits the seeds of loquats, almonds, and hempseed, with the same action as a Parrot when feeding. When I first had them, boiled potatoes and bread formed their diet; the former, being soft, were torn and swallowed in large pieces, but the latter they placed under their feet and tore with their hooked beak into small bits. It was supposed that these birds never drink water; this I soon found to be incorrect. They invariably feed in the light, but will not take food if any one be present. They run with great rapidity, elongating the body and depressing the head, and in the action of running resemble Grouse."
