A little penguin colony in Australia struggles during years with high penguin divorce rates, but the divorcees could have more offspring in the long run if they find better mates, a new study finds.

Little penguins on Phillip Island divorce partners after poor breeding seasons, impacting colony reproductive success.

Fertility troubles are a common stressor for couples, and it seems that penguins are no exception. A ten-year study found that although they do often ‘mate for life’, like humans, this doesn’t stop individuals from looking elsewhere.
