The resplendent quetzal is a very rare and elusive bird. It took me a long time to find this one nesting in a hollow tree in the cloud forest near San Gerardo de Dota in the Savegre river valley of Costa Rica. This is a male, he has an iridescent green head, wings, back and chest with a vibrant red belly. During the mating season male quetzals grow twin tail feathers that form an amazing train up to three feet (one metre) in length. You can see his beautiful long green tail poking out of the hole, above his head, as he could not fit his entire tail in the nest! I watched as the male and female took it in turns to find food for their chicks, while the other bird stayed to guard the nest. Although reputed to be the most beautiful bird that exists in the American continents and much loved in Costa Rica, the resplendent quetzal is now an endangered species and listed as ‘Near Threatened’.
