Smells could lure predators away from native birds
Researchers have developed an unusual weapon in the battle to protect New Zealand's native birds from mammalian predators - smells. Over two nesting seasons, the researchers from Landcare Research and the University of Sydney used "odour cues" to lure predators away from nesting sites in Canterbury. And the results, they say, are highly encouraging. Landcare's Grant Norbury is the project's lead researcher, he spoke to Corin Dann.
