about eight or ten being seen on a single tree, crowding against one another on the same dead branch, but never in such numbers as to deserve the appellation of flocks. Each bird appeared to act independently of the other, each, as the desire for food prompted it, sallying forth from the branch to capture a passing insect, or to soar around the tree and return again to the same spot. On alighting it repeatedly throws one wing out at a time, and spreads its tail obliquely, previous to settling. At other times a few were seen perched on the fence surrounding the paddock, on which they frequently descended like Starlings, in search of coleoptera and other insects. It is not, however, in this state of comparative quiescence that this graceful bird is seen to best advantage, neither is it at that state of existence for which its form is especially adapted; for though its structure is more equally suited for terrestrial, arboreal, and aërial habits than any other species I have examined, yet the form of the wings point out the air as its peculiar province. Here it is that when engaged in pursuit of the insects which the warm weather has enticed from their lurking-places among the foliage to sport in higher regions, this beautiful species in its aërial flights displays its greatest beauty, whilst soaring above in a variety of easy positions, with its white-tipped tail outspread." The voice of these birds resembles the call-note of the Swallow, but is somewhat harsher and more monotonous. Some are stationary, while others wander from one place to another as soon as the period of incubation is over. The Wood Swallow makes its appearance in Van Dieman's Land in October, at the commencement of the Australian summer; and after rearing two broods returns again to more northern latitudes. The nests are built in a great variety of situations. Gould found one in a thickly-foliaged bush close to the ground, another placed in the fork of a bare branch, and others under the loose bark of a large tree; they are also frequently placed under the roofs of the settlers' houses; and one species in particular prefers to avoid all labour by taking possession of the deserted nests of other birds. Their own nests are usually neatly formed of delicate twigs, woven together, and lined with fine fibrous roots. The four eggs that constitute a brood are generally of a dirty white, spotted and streaked with reddish brown. Bernstein tells us that the species inhabiting Java build amid the parasitic plants that cover their favourite palms, or upon the leaves of the tree itself, forming their little abodes of grass, moss, fibres, and small leaves, carelessly arranged, but strongly lined with soft and elastic materials. The Indian species, according to Jerdon, makes a bed of feathers inside its nest. Many of the members of this family remain in company even during the breeding season, and build in close proximity to each other. It is still
