These two adelie penguins were putting the run on all of these emperor penguins as they marched past ice bergs on their way back to their colony on the Ross Sea, Antarctica. Once they were done picking on the emperor penguins, they decided to come over and challenge me. All penguin species have different personality traits and adelie’s definitely seem to be the most fearless.
