Of the second group, _C. uniappendiculatus_ (Fig. 10), of Salawatti and the adjoining parts of New Guinea, has the head, throat, and nape blue, the lower portion of the neck and the median pear-shaped caruncle yellow, the casque dusky olive, and a longitudinal naked space towards the sides of the neck flesh-coloured with a yellow margin. _C. occipitalis_ of Jobi Island is distinguished from the last-named by a large occipital spot of yellow and a paler helmet; while the remaining three forms have no wattle at all. Of these, _C. papuanus_, of North-East New Guinea, has a dusky black casque, blue head, throat, and fore-neck, grey-green occiput and auricular region, and orange hind-neck changing into rosy flesh-colour towards the sides. _C. picticollis_ of South-East New Guinea has a black helmet, grey-blue occiput, violet-blue nape, pale blue hind-neck, red throat and longitudinal space on the sides of the lower neck; _C. bennetti_ of New Britain differing in having the head and neck of an almost uniform blue. Nestling Cassowaries are clothed in rusty brown, relieved by darker stripes; at a later period they become more tawny, and the black plumage begins to appear; but a few hair-like feathers remain on the head for some time, while the helmet is very gradually developed from a flat Coot-like shield, though the gaudy colours of the neck and wattles are assumed much earlier.[22] All the species of this family inhabit wooded country, commonly of the densest description, though often found in more open scrub and in the neighbourhood of creeks and watercourses. Naturally shy but inquisitive, they have been rendered doubly wary by man's persecution since their haunts have been invaded by colonists. They dislike the sun, and emerge from cover only in the morning and evening, seeking their favourite spots, where they feed chiefly on fallen fruit, varying this diet with insects and crustaceans. Berries, leaf-buds, and bulbs are, however, also eaten, with grit and pebbles for digestive purposes, and in captivity they are almost omnivorous. {35}[Illustration: FIG. 10.–One-wattled Cassowary. _Casuarius uniappendiculatus._ × 1/14.
