Noisy miners are native Australian honeyeaters that form colonies and aggressively displace other woodland birds from areas they occupy. Habitat clearing, fragmentation, and degradation has created more suitable habitat for noisy miners. Their impacts are greatest on smaller-bodied woodland birds, including some Critically Endangered species. Lethal methods to control noisy miners have been trialled intermittently over the past three decades, but with varying success. We aimed to determine which methods or ecological conditions led to successful noisy miner removals, in terms of both reducing noisy miner density and increasing the diversity and abundance of small woodland birds.
