There are several negative consequences to this change in behaviour.
- Conflict with local communities. Kea that don’t need to spend time foraging, spend more time investigating and damaging human property.
- Lead poisoning. Kea that are encouraged to hang around human settlements (such as Arthur’s Pass) are also ingesting and dying from lead from flashings and nail heads on old buildings.
- Kea that are attracted to and focussed on novel food items in areas where humans visit, are less likely to be cautious around baits and more likely to ingest a lethal amount of toxin.
- Ingestion of other toxic items mistaken for food such as chocolate (Gartrell & Reid 2007) and household rubbish.
- Car strike and accidents as a result of kea scrounging for food around car parks and roadways.
