Frigatebirds - Courtship!

Male frigatebirds have one of the most dramatic courtship displays in the animal kingdom. During mating season, the males gather in groups and inflate enormous bright red throat pouches that look like giant balloons. They sit in trees for hours, sometimes even days, trying to attract females flying overhead. While showing off, the males vibrate their wings, shake their heads, and make rattling sounds with their bills to stand out from the crowd. The bigger and brighter the red pouch looks, the more attention they usually get from females. The display may look funny to humans, but it is actually a serious competition. Female frigatebirds carefully inspect the males before choosing a mate, while unsuccessful males can spend an entire breeding season without attracting anyone.
