A 10-year-old king penguin formerly named "Maggie" was renamed "Magnus" after zookeepers observed unexpected mating habits and sent feathers out for DNA testing, which revealed that she was male.

In the wild, king penguins usually begin to fledge—a bird’s first molt, when it loses its downy plumage—around 13 months after they hatch. Pesto, born in January of this year, is a little early.
