The _Eöpsaltria griseogularis_ is abundant in every part of the colony of Swan River, inhabiting thickets and all spots clothed with vegetation of a brush-like character. “In its actions,” says Mr. Gilbert, “this bird is very like the Robins, being much on the ground, and when feeding constantly flying up and perching on a small upright twig. It does not appear to be capable of great or continued exertion on the wing, as it is rarely seen to do more than flit from bush to bush. Its most common note much resembles the very lengthened and plaintive song of the _Estrelda bella_, but differs from it in being a double note often repeated; it also utters a great variety of single notes, and during the breeding-season pours forth a short but agreeable song. “The nest is very difficult to detect, the situations chosen for it being the thickly wooded gum-forests of the mountain districts and the mahogany forests of the lowlands; from the forks of the younger of these trees a great portion of the bark generally hangs down in strips; and in the fork the bird generally makes its nest of narrow strips of the bark bound together with cobwebs, while around the outside a quantity of dangling pieces are suspended, giving it the exact appearance of other forks of the tree; the inside of the nest has no other lining than a few pieces of bark laid across each other, or a single dried leaf, large enough to cover the bottom. It breeds in September and October, and lays two eggs, which are more lengthened in form than those of _Eöpsaltria Australis_, and are of a wood-brown obscurely freckled with yellowish red, ten lines long by seven lines and a half broad. “Its stomach is muscular, and its food consists of insects of various kinds.” The sexes are precisely similar in outward appearance. It is stationary in Western Australia, but the extent of its range over the continent is not yet known. Crown of the head, ear-coverts, sides and back of the neck, and back grey; throat and chest greyish white; abdomen, rump, upper and under tail-coverts rich yellow; wings and tail greyish brown, the extreme tips of the latter edged with white; bill dark horn-colour; irides very dark reddish brown; legs and feet dark olive-brown. The figures are male and female, of the natural size. [Illustration: EÖPSALTRIA LEUCOGASTER: _Gould_. _J. Gould and H. C.
