Laguna Colorada is considered by most to be the crown jewel of Reserva Nacional de Fauna Andina Aduardo Avaroa. The bustling flamingo colonies here are the primary reason some 40,000 travelers each year venture deep into this Andean wilderness on rugged backroads, and this destination is unlikely to disappoint any time of year. Bring your binoculars and join the flock.
Flamboyances of Flamingos
Up to 60,000 flamingos from three different species mingle in the warm, geothermal waters here. From viewpoints on shore, flamingos can be found plying the lagoon’s waters for microscopic algae and shrimp, using their scoop-like beaks to filter tiny creatures into an easy meal. These mercurial birds play an underrated role in the history of evolution. They are one of just three bird species (the others being penguins and doves) that produce milk for their young. Both male and female flamingos possess this trait, which scientists believe may be an evolutionary holdover from 30 million years ago.
While the largest, brightest flamingos here may draw your eye first, pay special attention the smaller, paler James’s flamingos. This species was thought to be extinct until the 1950s, when the colony here was discovered.
Flamingo populations are healthy in the area, but scientists say climate change will impact Laguna Colorada. Increased rainfall in the Andes produced by rising temperatures can alter the pH balance of the salty lagoon, shifting its color from red to teal. Stronger storms can even flood flamingo nests and destroy colonies.
