The rich brown Pilot Bird rarely flies, but keeps low down in the dense tangles and undergrowths in country like that about Ferntree Gully. It must be patiently waited for, as it is very shy. It, apparently, values its services highly, for it often calls "A-guinea-a-week." The larger Scrub-Robin which lives only in the interior flies little, but, as shown in the figure, it has long legs, suitable for running. Its color is not the dark-brown suitable for dark scrubs, but is the light-brown which matches the dead mallee twigs lying so thickly on the ground under the scrub. We met the Scrub-Robin on Eyre Peninsula, but it was difficult to get a second look at it. Almost as rare are the closely-similar Chestnut-rumped and Red-rumped Ground-Wrens. Few will see these birds, as they live only in the drier parts. That interesting bird--the Coachwhip Bird--is far more often heard than seen. Along the densely-scrubbed creeks of Eastern Australia, the interesting whip-crack of this bird is very often heard. An exact representative lives in West Australian scrubs. I was surprised to hear, in several places lately, the Rufous-breasted Whistler (Thickhead) called the Coachwhip Bird. It has been found that both birds take part in the peculiar call which has a loud crack very like that of a whip. This bird dwells in the dense eastern scrubs, and uses its short wings but little for flight. It was seen, however, recently at Sandringham, a few miles from Melbourne. The Australian Babblers are of interest from all points of view. Their habits are peculiar; their calls are varied and usually pleasant, and their large domed stick nests are common objects along a country road. Usually seen in companies of from four to a dozen, these birds work energetically and systematically. They are entirely insectivorous, and so are of great value economically. They are tame, as I have watched a flock at work in the gardens in the middle of a town such as Dunolly. They occasionally visit orchards and attack the codlin moth pupae. They are said never to squabble, and so are called "Happy Family" or "Happy Jacks." Their names, however, are many. The commonest is, perhaps, "Catbird." There is a "Catbird," a Bower-Bird, in Queensland, so the use of that name should be discouraged. Babblers sometimes make six or seven nests, laying only in one. The others are said to be shelter nests, or possibly play nests. That pleasing songster--the White-browed Field-Wren--is uniformly streaked with black both above and below. It is fairly common, but is not often seen unless looked for. Dogs will follow the scent of this bird, as they do that of a quail; so it is sometimes called the Stink-Bird by sportsmen.
