Flamingos are very common at lakes in the NCA, all of which are saline. Flamingos are filter feeders and feed on plankton. Plankton is a collective name for microscopic plants and animals that occur in the mud and on the surface of shallow, saline lakes.
The mixture of forest, canyons, grassland plains, Lakes and marshes provide habitats for a wide range of bird life. The wet months see the arrival of the Eurasian migrants at the pools. White storks, yellow wagtails and swallows mingle with the local inhabitants: stilts, saddle-bill storks, ibis, ruff and various species of duck. Lesser flamingos fly in to feed from their breeding grounds at Lake Natron. Distinctive grassland birds - ostrich, kori bustards and crowned cranes-abound. The rest of the NCA also has areas which will reward the keen ornithologist.
