One group of penguins in the Cape Royds penguin colony are closely observed in this enclosure. They can only exit through the gate seen here where they pass across a bridge that is actually a very sophisticated scale that measures their weight while a sensor reads the number of the tag that is on their shoulder. This way the weight of the penguins going in and out to feed is monitored and recorded by a computer that sits in a tent next to the enclosure. Since the penguins are tagged when they are chicks their whole development can be followed this way.
