African penguins celebrate Valentine's Day
A few penguins got a chance to celebrate with their valentine's in California.
At the California Academy of Sciences, a group of African penguins were given heart-shaped tokens during their daily feedings.
Most male birds would come up and grab the felt valentines, then go offer them up to female penguins.
If a penguin didn't have a valentine, they would place their heart-shaped tokens in nests, encouraging breeding.
Experts say the hearts help the penguins continue to bond with their mates.
