This bird occurs in considerable numbers throughout the whole of the southern portion of Australia during the months of summer; it is strictly migratory, arriving in the month of September, when insects are most plentiful, and having performed the task of reproduction departs again northwards in the months of January and February. It is a most animated, lively and spirited bird, constantly singing a loud and pretty song while actively engaged in pursuit of insects, which it either captures on the wing, among the branches or on the ground. It commences breeding soon after its arrival, constructing a shallow round nest of small pieces of bark, short dead twigs and grasses interwoven with fine vegetable fibres, cobwebs, white moss, &c., and sometimes a few grasses and fine fibrous roots by way of lining; it is usually placed in the fork of a horizontal dead branch of the apple- and gum-trees, and is not easily seen from below. During the early part of the breeding-season the male frequently chases the female from tree to tree, pouring forth his song all the while. The eggs, which are generally two, but sometimes three in number, differ very considerably in colour, some being of a light green blotched all over with wood-brown, while others have a lighter ground so largely blotched with chestnut-brown as nearly to cover the entire surface of the shell, and I have seen some of an almost uniform greyish green; their medium length is nine and a half lines and breadth seven and a half lines. The above is a detail of what I myself observed of the bird in New South Wales. In his Notes from Western Australia, Mr. Gilbert says, “This bird is a migratory summer visitant to this part of the country, where it arrives about the beginning of September, after which it is to be met with in considerable numbers among the mountains of the interior, but is very rarely seen in the lowland districts.
