Grallina picata (Magpie Lark).—A very common species throughout the district, anywhere in the vicinity of water. As a rule they breed here in great numbers, but for some unaccountable reason during the present year (1917) very few of them bred at all. I did not see half-a-dozen nests occupied. Most ol tli' nests contain eggs during the latter part oi September and October, but I have found Fresh eggs .!^ Lit'- ,i> December 1st. Four eggs constitute the usual number for a sitting, but they often lay five, and they place their nests at various heights, some are to be seen quite low down, near the surface of the water, while others are as much as seventy feet above. Gymnorhina tibicen (Black-backed Magpie). Although this species is far from common any- where in the district, scattered pairs and small flocks are to be met with in the more open forests, and ring-barked country. Once they take up their abode in any particular locality, they usually remain thereabouts for years, sometimes building a new nest in the same tree season after season, but they only rear one brood each year, and the young birds remain with their parents till the approach of the following breeding season. I have examined a great number of their nests, but have never seen one containing eggs earlier than August 22nd, and none later than October 24th. They mostly lay four eggs for a sitting. I have never found a larger clutch, and it is seldom that two clutches from different birds are found exactly alike in colour and markings.
