Wildlife Wednesday: Nesting Adélie penguins

1 Comment

Unlike their cousins the emperor penguin, and despite what most people expect, Adélie penguins do not nest on the ice. In fact, they need ice-free areas of gravel to breed on over the summer months. This is largely because they build nests of small stones in which to lay their eggs. Stones are a valuable resource in a penguin colony and it’s not uncommon to see birds stealing stones from their neighbour’s nest when they think no one is looking. This stealing behaviour means that the nests are often very evenly-spaced, at a distance that is slightly beyond the reach of the neighbour.

Occasionally someone will branch out into alternative building materials. For some reason, this bird decided that the dessicated remains of dead penguin chicks are better than stones. Unfortunately, the ladies didn’t agree and he wasn’t successful in finding a mate.  Sometimes it doesn’t pay to be different!
