The Lesser Flamingo (Phoenicopterus minor) is a species in the flamingo family of birds which occurs in Africa (principally in the Great Rift Valley), across to Pakistan and northwest India. It is the smallest and most numerous flamingo, probably numbering up to two million individual birds. In Africa, where they are most numerous, the Lesser Flamingos breeds principally on the highly caustic Lake Natron in Northern Tanzania. Like all flamingos, they lay a single chalky white egg on mounds they build of mud. Most of the plumage is pinkish white.
