The Inca Tern (Larosterna inca) mustache you a question—have you ever seen a more debonair bird?
It might be spotted along the Pacific coast of South America, where it lives in large colonies that can number up to several thousand individuals.
This sea bird prefers to hang out around the cool Humboldt Current, which provides it with plenty of anchovies to munch on. Both males and females of this species don striking white mustaches.
