Penguins Stuck In Infinite Loop
mjd writes "All dressed up and nowhere to swim! ABC News reports that "the penguin pool at the San Francisco Zoo has been a daily frenzy of circle swimming by all of the 52 birds at once. The penguins start swimming in circles early in the day and rarely stop until they stagger out of the pool at dusk.""
Circle swimming happens every so often in the penguin exhibit at the Omaha Zoo. They have a very nice display, which happens to include a penguin webcam. I think for the most part the Omaha penguins are more laid back than their San Francisco inmates. Also, here is a map of the aquarium where the keep the penguins. Enjoy.

Except in the wild, they don't swim all day from dawn to dusk. It depends on the species, but most penguins spend most of the day sitting around on the ice, or meandering about lazily.
Swimming around in circles all day could be a sign of a problem.
This isn't the same species, but how about swimming for 18 days at a time, and diving to 500m. That doesn't sound terribly idle. (http://www.penguins.cl/king-penguins.htm)
For this species, they migrate from Tierra Del Fuego to Brazil. That's got to be a decent swim.

Or how about "The satellite data have already revealed that some penguins swim up to 300 miles from their nesting area to find food while their mates sit in the nests on their eggs. Such a foraging journey can take nearly three weeks, leaving the penguins' newborn chicks at risk of starving before the parent returns. This is particularly worrisome since the number of Magellanic penguin chicks surviving to adulthood has declined in recent years."
