Considered among the most beautiful birds in the world, the female is covered in brilliant blue, green, and red coloring; however, the breeding males, which are more vibrant, seem almost impossibly striking.

This means that when taking their turn to incubate the 2–3 eggs laid inside tree trunks, the males tend to fold their feathers over their backs to stay out of sight. Even so, sometimes their feathers are so long that they seem to stick out.

As might be expected, the feathers play an important role. As the male tries to impress his female counterpart during mating season, he flies down from tall trees to show his elongated feathers behind him. In addition to their beautiful display, males also sing to the females.

The bird’s tail feathers have been culturally significant. By capturing Resplendent Quetzals, plucking their tail feathers, and then setting them free, people created headdresses for the Aztec ruling class.

As for the Mayan people, the Quetzal also had quasi-divine status. Their inability to domesticate the bird and get it to reproduce in captivity made it a powerful symbol of freedom. The rare feathers that fell or were plucked came to be a valuable form of currency, which made “Quetzals” the perfect unit for Guatemala’s currency, introduced in 1925.
