Control predators not on islands for songbirds Bird Conservation

A controlled before-and-after study in November-December 1999 in a 240 ha eucalypt forest in New South Wales, Australia (Fulton & Ford 2001), found that 104 artificial nests survived for significantly longer following the removal of pied currawongs Strepera graculina from an experimental grid (average survival of 1.9 days before cull vs. 3.0 days afterwards). There was no change in a nearby control grid, without currawong removal (3.1 days before vs. 3.6 afterwards). Before the cull, survival was significantly higher on the control grid, but there was no difference following the cull. Three pairs of currawongs were culled, with three more nests having either fledged or failed by the time of the cull in early December 1999.
