The TUFTED HONEY-EATERS (_Ptilotis_) are remarkable for the unusual development of the feathers in the region of the ear. Their body is elongate, their wings short, and tail long. The strong, slightly-curved beak is short, and the foot of moderate size.
The YELLOW-THROATED TUFTED HONEY-EATER (_Ptilotis flavigula_) is yellowish green on the back, wings, and tail. The dark grey under side glistens with a silver sheen; the belly and sides are pale olive, the top of the head dark grey, and the throat bright yellow. The feathers that compose the ear-tufts are tipped with yellow, and the outer web of the quills is deep brown. The eye is brown, the beak black, and the foot lead-grey; the gullet and tongue are of a brilliant orange-red. The length of this bird is eight inches; the wing measures four inches and a half, and the tail four inches and a quarter.
"This fine and conspicuous species," says Gould, "is abundant in all the ravines around Hobart Town, and is very generally spread over the whole of Van Dieman's Land, to which island I believe it to be exclusively confined. It is very animated and sprightly, extremely quick in its actions, elegant in its form, and graceful in all its movements; but as its colouring assimilates in a remarkable degree with that of the foliage it frequents, it is somewhat difficult of detection. When engaged in searching for food, it frequently expands its wings and tail, creeps and climbs among the branches in a variety of beautiful attitudes, and often suspends itself to the extreme ends of the outermost twigs. It occasionally perches on the branches of trees, but is mostly to be met with in dense thickets. It flies in an undulating manner, like a Woodpecker, but this power is rarely exercised. Its note is a full, loud, powerful, and melodious call. The stomach is muscular, but of very small size, and the food consists of bees, wasps, and other hymenoptera, also of coleoptera of various kinds, and the pollen of flowers. It is a very early breeder, as is proved by my finding a nest containing two young birds covered with down, and about two days old, on the 27th of September. The nest, which is generally placed in a low bush, differs considerably from those of all other Honey-eaters with which I am acquainted, particularly in the character of the material forming the lining. It is the largest and warmest of all, and is usually formed of ribbons of stringy bark, mixed with grass, and the cocoons of spiders; towards the cavity it is more neatly built, and is lined internally with opossum's or kangaroo's fur. In some instances the hair-like material from the base of the large leaf-stalks of the tree-fern is employed for the lining, and in others there is merely a flooring of wiry grasses or fine twigs. The eggs, which are either two or three in number, are of the most delicate fleshy buff, rather strongly but sparsely spotted with small prominent roundish dots of chestnut-red, intermingled with which are a few indistinct spots of purplish grey. The average length of the egg is eleven lines, and the breadth eight lines."
