I used remotely trigered 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 microswitch
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
Colluricincla
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.
