New Study Ranks New Zealand’s Kea as Smarter than Cockatoos

A recent study has determined that New Zealand’s native bird, the kea, exhibits greater intelligence than cockatoos. Researchers at the University of Vienna focused on how these parrots respond to unexpected changes in their food rewards, specifically measuring their emotional reaction to being given less desirable items.

In the experiment, kea were presented with a peanut but received a piece of apple instead. This switch led to visible signs of surprise and disappointment in the kea, which actively searched for the expected peanut. In contrast, the cockatoos displayed little to no reaction to the altered food offering.

Insights from a Conservationist

Dr. Laura Young, a conservationist associated with the Kea Conservation Trust, expressed that the findings confirm her long-held belief in the kea’s intelligence. “I’m not surprised; kea are pretty clever. They seem to work together quite well,” Dr. Young explained. Her observations over the past 15 years have shown remarkable behaviors in kea, including their ability to solve problems and adapt to their environment.

One notable instance occurred on Milford Road near the Homer Tunnel, where traffic was halted due to road cones placed by construction crews. Dr. Young and her team discovered that kea were pulling these cones into the road, effectively stopping traffic and seemingly enjoying the chaos they created.

Conservation Efforts and Challenges

Despite their cleverness, the kea face significant threats. Dr. Young highlighted the issue of lead poisoning as a critical concern for the species. Keen observers of their environment, kea are attracted to sweet-tasting materials, including lead-based hut nails and flashings. They can also encounter lead ammunition when scavenging on the carcasses of animals shot by hunters.

In response to this threat, the Kea Conservation Trust has shifted its focus towards reducing lead exposure among kea. Dr. Young noted a successful campaign advocating for the replacement of lead ammunition in government culling programs and the removal of lead nails from village buildings where kea are known to frequent.

To support the kea population, Dr. Young encourages New Zealanders and tourists to report sightings to the conservation trust’s database. Moreover, she cautions against behaviors that could lead to problematic interactions with the birds. “Do not feed kea or leave your gear unattended, as it encourages them to engage in undesirable behaviors,” she advised.

By understanding and respecting the unique intelligence and needs of the kea, the public can play a vital role in ensuring the survival of this remarkable species.
