16. Magnificent and Great Frigate Bird

Meet the not-so-passive-aggressive, but rather downright competitive, Frigate Birds with a hunting strategy that earns them the title of ‘pirate birds.’ In a rather unconventional approach, these birds forgo solo hunting expeditions and instead target other avian species, such as the Blue-Footed Booby. They deftly seize the tail feathers of their unsuspecting counterparts, vigorously shaking them until the freshly caught meal is relinquished. This unique behavior cements their reputation as the swashbucklers of the avian world.

The reason behind their unconventional hunting technique lies in their own vulnerability. These magnificent creatures lack waterproof feathers, rendering them waterlogged after just a minute in the ocean. Fascinatingly, young Frigate Birds practice their piracy skills using small sticks, holding them in their beaks while engaging in a sibling-driven pursuit. The chase culminates with a daring dive to catch the dropped stick, honing their aerial acumen. Distinguishing between males and females is a breeze; males exhibit a bright red pouch on their necks and are notably smaller than their female counterparts.
