Lesser Flamingo

 

Two Lesser Flamingos

Scientific name: Phoeniconaias minor
IUCN designation: Near Threatened

The Lesser Flamingo is the smallest of six flamingo species across the world and is the AMASS project’s focal species from Europe-Asia-Africa1,2.

The Lesser Flamingo is easily identifiable, being pink in color and having a height and wingspan of 1 m (3.3 ft)3. The saturation of its pink plumage depends on levels of beta-carotene that it consumes from its diet of cyanobacteria1. Its primary and secondary feathers are black and its wing coverts are red. The Lesser Flamingo has orange-yellow eyes which are surrounded by a maroon or a purple eye-ring1,3. It has a deep-keeled bill that curves downwards. Its bill is primarily dark red and has a black tip3. You can distinguish the Lesser Flamingo from the Andean and Puna Flamingos by its hallux (hind toe)3.

Juvenile Lesser Flamingos are grey in color4. As they age, their grey natal down gets replaced by a coarser brown down4.

There are five main breeding populations of Lesser Flamingo in the world. The main breeding population occurs in the Rift Valley Lakes of East Africa (Ethiopia, Kenya, and Tanzania). One Rift Valley lake, Lake Natron, hosts 75% of the world’s breeding population5. The other breeding populations occur in West Africa (Senegal and Mauritania), Southern Africa (South Africa, Botswana, and Namibia) and South Asia (India and Pakistan)5.

The Rift Valley Lesser Flamingo population is itinerant, migrating to different alkaline lakes in response to changes in environmental conditions of its wetland habitats6.

The partially nomadic Southern African and Asian populations frequently make movements between their inland breeding sites and coastal non-seasonal breeding areas5.

The survival of the Lesser Flamingo is entirely dependent on environmental conditions and the ecological integrity of these alkaline lakes thereby making the Lesser Flamingo extremely susceptible to industrial pollution and anthropogenic activities, such as the soda ash extraction industry5.
