Kea Lore

Andrew located this Eric Hoffman story about New Zealand's famed parrot, the kea:
The birds belong to a species called the kea (Nestor notabilis), a maverick member of the parrot family, described as everything from a fun-loving prankster to a heartless mountain mobster that knows no bounds when it comes to procuring a meal. Indigenous to the high country of South Island, the bird is loved by many and hated by some, and its antics frequently solicit moralistic comparisons to human misbehavior.

...'Keas like to have fun, and they express play in many different ways. When it comes to behavior, there is no other bird like them. They are cunning, calculating, and highly intelligent,' says Wayne Schulenburg, animal-care manager for the bird collection at the San Diego Zoo. Schulenburg has firsthand knowledge of keas both in captive settings and in the alpine wilds of New Zealand.

In New Zealand, just when you've heard the most unbelievable kea story, there is always another one. Keas demolishing automobiles is a recurring topic. Hikers leaving cars in ski resorts or trailheads sometimes return to find their windshield wipers shredded and a couple of keas dragging the remains around the parking lot. Or a mischievous pair of keas may leave the windshield wipers alone and instead make a day of prying off chrome strips.

...Sometimes they display an almost humanlike ability to avoid culpability. Schulenburg likes to tell the story of Lucy, a particularly clever kea who lived for years at the San Diego Zoo. 'She figured out how to break open the lock to her cage. One night she got loose and entered the keeper's quarters and the kitchen. She ate everything edible, totally destroyed a down sleeping bag, and carried coffee mugs to the edge of the counter and dropped them to the floor, reducing the mugs to a pile of pottery shards. Another night she escaped and methodically opened 20 other cages containing dozens of other species of birds that were part of special breeding programs. In the morning, when we came to work, we couldn't believe our eyes. Most of the birds were gleefully zooming around in areas that had been taboo. Lucy played it innocent. She and her mate had gone back to their cage and shut the door behind them, but the telltale broken lock gave away who was behind the breakout.'

...Allison Archambault, a U.S. veterinarian specializing in parrot medicine, has had a few encounters with the opportunistic and predatory nature of keas while visiting her family in New Zealand. When a fierce storm from the Subantarctic overtook Archambault and her friends, they faced a grueling hike over a precipitous icy trail to reach safety. 'I fell several times, became disoriented, and actually feared I might not survive. When I glanced behind, I found it sobering to find five keas quietly walking along behind me only a few feet away. They recognized I was in trouble and saw me as a potential meal, just as they do sheep that wander into their highland haunts during the harsh winter months.' She lived to tell her tale and the keas were out a meal, but such brazenness and ability to size up a situation and capitalize on it have put the parrots in direct conflict with sheep farmers.

...The obvious question is, Why is this parrot species so smart? Olsen hazards a theory: 'The kea represents a link with the ancient evolutionary past and is an omnivorous parrot--not a specialized feeder as is the case with most parrots living today. Its brain is a distinguishing attribute that gives it the edge in a harsh world.'
