The nest is a round open cup-shaped structure, and is usually formed of fine strips of bark,lined inside with dried grasses or wiry rootlets, the whole exterior and rim, which is thickrounded, being coated with green moss. Others I have seen constructed outwardly entirely oftea-tree bark and dead leaves, and the exposed portion of two nests decorated with pieces ofpale green and white lichen, like some nests of Eopsaltria austraUs, The nests, too, vary in size,. MOUNTAIN THRUSH. 236 for they are resorted and added to season after season. The materials forming the lowerportion of the original nests, owing to excreta, rains, and storms, become decomposed andconsist chiefly of mould and decayed vegetable matter. This is more apparent when attemptingto remove one of these long-resorted to structures from a thick forked branch. An average nestof the year measures externally seven inches and a half in diameter by four inches in depth; theinner cup three inches and a half in diameter by two inches and a quarter in depth; rim twoinches. The position of the nest varies with the localities in which it is found. The favouritesite near the coast is in a fork near the top of a tea-tree; and on the mountain ranges, wedgedbetween the thick forked trunk of a smooth barked gum-tree, or on a moss-covered horizontalbranch of any tree growing in a secluded gully.
