Action: Use mirrors to deter nest predators
Key messagesRead our guidance on Key messages before continuing
- We found no evidence for the effects of mirrors on nest predation rates.
'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.
Anecdotal evidence suggests that fixing mirrors to nest boxes may reduce predation rates by species such as great spotted woodpeckers Dendrocopos major.
