For the first time, researchers are exploring ways to improve welfare in captive birds of prey through olfactory enrichment- or using scent cues to alleviate boredom and encourage species-appropriate behavior. A new study appearing in Zoo Biology found that birds of prey, which had learned to associate the presence of food with the scent of peppermint oil, interacted more with peppermint-scented “sham” packages (i.e. without food) than unscented “sham” packages.
