Using five-minute bird counts to study magpie (Gymnorhina tibicen) impacts on other birds in New Zealand

Investigates whether introduced Australian magpies (Gymnorhina tibicen) influence the abundance of other birds in rural New Zealand, using the five-minute bird count (5MBC) method. Discusses behavioural interactions between magpies and other birds, strengths and weaknesses of the 5MBC method, and circumstances in which such index counts are (and are not) appropriate.
