CONCERN has been expressed at the possibility of the extinction of the lyre-bird in Victoria, but F. Lewis, chief inspector of fisheries and game, points to the improvement which has taken place in public opinion, the more rigorous protection by law, and the fact that a great deal of the land inhabited by lyrebirds is rough and inaccessible (Victoria Naturalist, 53, 12; May 1936). He is of opinion that the future of the lyre-bird is assured, granted that public opinion in favour of protection continues to be educated in country districts as well as in the cities, and that a stop should be put to the clearing of lyre-bird gullies and the destruction wrought by bush-fires and the activities of egg-collectors. In another paper in the same journal (p. 3), R. T. Littlejohns- states that no other Australian bird adheres so strongly to a definite area. In this case, the territory is two or three acres in extent, and for week after week, especially during the singing season, the place of any particular individual may be known exactly. It is seldom indeed that a bird is to be found outside its own area.
