Magnificent Frigatebird

When you first view the Magnificent Frigatebird's vivid crimson neck, it's simple to think that it is lovely but not very unusual in comparison to other bird species. But if you saw it during mating season, you would reconsider your stance. The reason for this is that the males of this subtropical bird species have the ability to inflate the pouch around their neck until it resembles a huge red balloon. And oddly enough, it appears that this feature is only there as a mate-attraction strategy. Females of the species don't even have the pouch itself.

These birds can't swim, even though they can be found in both the Atlantic and Pacific. Fortunately, these unusual birds can fly much farther than other types of birds due to their large wingspan, which in males can measure up to eight feet. The males of this species are known to have the world's largest bird wingspans.
