Flamingos have a reputation for being delicate and pink, but this iconic bird is actually well-adapted to the harsh environments in which it lives. This remarkable species thrives in specific wetland habitats around the world, including salt lakes and lagoons. Their long legs and specialized food-filtering systems have evolved to allow them to live in habitats that would be deadly for most other animals.
Flamingos eat a variety of microorganisms found in muddy or silty waters, including algae and small crustaceans. Their beaks are specially adapted to filter the microscopic organisms out of watery, saline environments, making them one of the most successful avian species for living in these harsh conditions. Their unique beak shape and color allow them to see the watery food sources that would otherwise be invisible to the naked eye.
The flamingos’ long legs and necks are also important adaptations for foraging in shallow water environments. Their long legs are adapted to wade through water, and they use them to stir up microorganisms from the bottom of the shallow pools in which they search for food. The flamingos’ beaks have evolved to filter the water and retain the food items, which they then consume. Their tongues can pump up to six times per second, separating the tiny food particles from the silty waters. Their feet are adapted for standing on mud or sediment, allowing them to create a vortex in the water with each stamp they make.
Another interesting adaptation is the flamingos’ ability to rely on their long necks to detect vibrations from potential predators and other members of the flock. This is how they can maintain a protective synchronized display during courtship, mating, and egg laying. The flamingos’ long necks are also crucial for vocalization, which helps parents recognize their chicks and communicate with them during feeding time.
Like other birds, flamingos can regulate their body temperature through heat loss and retention by maintaining a countercurrent system of blood flow through their legs. This allows them to efficiently use the energy they’ve stored during a period of rest. They can also adjust their metabolism to maintain a steady rate in warm or cold conditions.
Flamingos are often seen resting on only one leg, which is a common posture for flamingos during their daily activities. This posture not only provides them with a more compact position to conserve body heat, it also reduces the surface area of their bodies exposed to the environment. This reduction in exposure to the environment allows flamingos to better control their body temperatures and prevent them from losing too much heat.
A crooked flamingo named Floyd recently came to the Zoo, and our wildlife care specialists helped him straighten his legs. They were able to do this by using an innovative technique called passive physiotherapy, which involves letting the flamingo stand in a tank of clean water while keeping the water flowing between his legs. The gentle movement of the water allows the flamingo to keep his legs warm and stimulates circulation, which promotes healing. This is just one of the many ways that we work with our animal partners to ensure they have healthy, comfortable lives.
