Used mainly by aquatic invertebrates, especially plankton, but also by baleen whales. When there is an increase in rainfall, the lake levels rise which leads to a rise in conductivity. Some disjunct populations have been located in the coastal regions of Madagascar. Scientists arent 100% sure why the birds do this, but the most popular theory is that it conserves energy. Changes in food quantity also influences the movement of the lesser flamingos. Females raise their tails while males depress theirs. They move from one lake to another based on food availability.

One factor that can reduce this success rate is predation. Their diet also includes algae like Synechocystis minuscula, Monoraphidium minutum, Synechococcus pevalekii and Synechococcus elongatus. Waterbirds, 23/1: 52-63. Lesser flamingos construct their nests in shallow water with wet soupy mud. This is due to the numerous vigilant individuals that are scanning for threats. Greater, Chilean and American flamingos have shallow-keeled bills, which allow them to eat. Flamingos have few natural predators because they live in remote, inhospitable places. When the water source becomes limited, they line up in a single file line to drink. The species can weigh from 1.2 to 2.7kg (2.6 to 6.0lb).

This is known as head flagging. Vareschi (1978) found that flamingo movements are triggered by the concentration of algae. They search for lakes that contain the highest concentration of food such as cyanobacterium Arthrospira fusiformis which is one of their main sources of food. East Africa is home to 75 percent of the world's population of lesser flamingos . (Childress, et al., 2009; Simmons, 2000; Tuite, 2000). BirdLife International.

Flamingos get their pink color from pigments in bacteria, called spirulina. Since they like to feed when the shallow waters are calm, it usually happens after the sun goes down. Every year, rippling pink streamers descend from the sky and settle on Lake Natron in Tanzania, materializing into thousands of mating flamingo pairs. The size of the flock can vary from a few birds to tens of thousands of birds. 2015a) Cannot fly and forage in bad weather (Snyder and Snyder 2000) On the ground (Finkelstein et al. The young completely break off into smaller groups, capable of flying and feeding independently. Lesser flamingos are filter-feeders, feeding with their head inverted and their bill floating on the surface of the water. Raised mud nests help keep flamingo eggs cool and dry. Lesser flamingos Chilean, Andean, and puna flamingos are found in South America; greater and lesser flamingos live in Africa, with greaters also found in the Middle East; the American or Caribbean flamingo is native to Mexico, the Caribbean, and the northernmost tip of South America. This pose is mimicked in seconds by the other birds. These mounds usually sit on a flat, terrace-like remnant of the sediment from which they were constructed. In head and neck hooking movements, flamingos walk forward in an erect position with their bills lowered to their upper necks in hook-like postures. While the bird sucks in water, minute organisms are filtered out by a comb-like projection of the tongue. Lesser flamingos feast on blue-green algae, which only grows in alkaline lakes. Although blue-green in colour, the algae contain the photosynthetic pigments that give the birds their pink colour. Accessed living in sub-Saharan Africa (south of 30 degrees north) and Madagascar. Lesser flamingo on shallow water | Image by Bishnu Sarangi from Pixabay. Flamingo chicks are fed a liquid diet by their parents.
