Both male and female resplendent quetzals have the bright body feathers, though the color on males is generally even brighter. During mating season, the males—like this one, photographed in Costa Rica—grow double tail feathers that usually measure longer than the bird’s body. In fact, some tail feathers can form a train up to three feet long. If you want to celebrate Draw a Bird Day today, maybe the resplendent quetzal will inspire you. Time to break out the crayons?
