In recent decades across eastern Australia, noisy miner populations have expanded in fragmented agricultural landscapes. A communal, nonmigratory, bird of considerable size (approximately 70g), they have aggressively outcompeted many other smaller species of native woodland birds. So concerning is this decline that in 2014, aggressive exclusion of woodland birds from potential habitat by noisy miners was listed as a Key Threatening Process under the EPBC Act. This project will determine if culling is an effective method to manage the impacts of noisy miners on threatened woodland birds.
