text: In general, evidence suggests the range and population of the Australian Magpie has increased with land-clearing, although local declines in Queensland due to a 1902 drought, and in Tasmania in the 1930s have been noted; the cause for the latter is unclear but rabbit baiting, pine tree removal, and spread of the Masked Lapwing (Vanellus miles) have been implicated.
