The Tawny-shouldered Podargus may be distinguished by the greater breadth of its markings, by the decided admixture of tawny in its colouring, by the feathers of the head having a small round spot of white at the tip, and by the more boldly-marked tips of the coverts. It is plentifully dispersed over New South Wales, where it is not restricted to any peculiar character of country, but inhabits alike the thick brushes near the coast, the hilly districts, and the thinly-wooded plains of the interior. I found it breeding on the low swampy islands studding the mouth of the Hunter, and on the Apple-tree (_Angophora_) flats of Yarrundi, near the Liverpool Range. In their habits and mode of life the _Podargi_ differ very considerably from the true Nightjars, and also in many particulars from _Ægotheles_. Like the rest of the genus, the Tawny-shouldered Podargus is strictly nocturnal, sleeping throughout the day on the dead branch of a tree, in an upright position across, and never parallel to, the branch, and which it so nearly resembles as scarcely to be distinguishable from it. I have occasionally seen it beneath the thick foliage of the _Casuarinæ_, and I have been informed that it sometimes shelters itself in the hollow trunks of the _Eucalypti_, but I could never detect one in such a situation; I mostly found them in pairs, perched near each other on the branches of the gums, in situations not at all sheltered from the beams of the midday sun. So lethargic are its slumbers, that it is almost impossible to arouse it, and I have frequently shot one without disturbing its mate sitting close by; it may also be knocked off with sticks or stones, and sometimes is even taken with the hand: when aroused, it flies lazily off with heavy flapping wings to a neighbouring tree, and again resumes its slumbers until the approach of evening, when it becomes as animated and active as it had been previously dull and stupid. The food consists of insects of various kinds; but in what way they are obtained is uncertain, though the contents of the stomach of one I dissected induce me to believe that it does not usually capture its prey while on the wing, or subsist upon nocturnal insects alone, but that it is in the habit of creeping among the branches in search of such as are in a state of repose; and an examination of the tail will, I think, serve to strengthen this supposition, since it in some degree resembles the form and structure of that organ in many of the climbing birds. The power it possesses of shifting the position of the outer toe backwards, as circumstances may require, is a very singular feature, and may also tend to assist them in their progress among the branches. A bird I shot at Yarrundi, in the middle of the night, had the stomach filled with fresh-captured mantis and locusts (_Phasmidæ_ and _Cicadæ_), which never move at night, and the latter of which are generally resting against the upright boles of the trees. In other specimens I found the
