Indentifying nest-predator species in a southern Victorian woodland using remotely triggered cameras at artificial nests

I used remotely triggered cameras placed at artificial nests to identify nest-predator species in Langwarrin Flora and Fauna Reserve, a woodland remnant in Southern Victoria. A quail egg placed on top of a micro-switch inside a disused bird nest acted as the bait and trigger mechanism for a camera placed nearby. After 220 camera days at 22 different nest sites, 15 nest sites had been depredated by the Grey Shrike-thrush Colluricincia harmonica and five had been depredated by the Little Raven Corvus mellori. Nest sites were more likely to be revisited, and were revisited more quickly, by Little Ravens than by Grey Shrike-thrushes.
