Predator swamping is an example of a behavioral strategy where group members synchronize their flight responses to warn the other members of any nearby threats. This obligate filter feeder often feeds at night and early morning when the surface of the water is calm. Young lesser flamingos move out of their breeding areas and into the gathering areas, unaccompanied by any adults after about 90 days. Lesser flamingos have the largest flocks of any flamingo species. ("International single species action plan for the conservation of the lesser flamingo Phoenicopterus minor", 2007; Brown and Root, 1971; Burch and Gailband, 2000; McCulloch and Irvine, 2009; Robinson, 2015; Scott, et al., 2012; Simmons, 1996).

Families with two males and one female also happen as do partnerships of two males and two females. They perform a variety of displays such as their head-wagging, head-bobbing, broken-neck posture, and ritual bickering display. The pink avian species is primarily nocturnal, meaning theyre most active at night. Lesser flamingos survival is dependent on the health of the planets alkaline and saline lakes and currently, things arent looking too hot in that department. [15] The only breeding site in South Africa, situated at Kamfers Dam, is threatened by pollution and encroaching development.[16]. This pose is mimicked in seconds by the other birds. The lesser flamingo is the smallest species of flamingo, though it is a tall and large bird by most standards. the area in which the animal is naturally found, the region in which it is endemic. Their regular breeding sites are located on the soda mudflats of Lake Natron in Tanzania and the pink crystalline soda palates. Humans have long been the biggest predators of the Flamingo though.

This is a huge problem in Africa where there is an abundance of these large cats looking for enough food to survive. The mounds are typically refurbished by the flamingos, applying fresh mud to rebuild them and increase their height. This has drastically reduced the number of new Flamingos in many regions. Pomeroy, D., A. Byaruhanga, M. Wilson. Size is less helpful unless the species are together, since the sexes of each species also differ in height. Their deep bill is specialised for filtering tiny food items. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. They make continuous goose-like honking calls to attract nearby females. young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. Lesser flamingos are believed to be the most numerous and live in the largest flocks. Ostrich, 68/2-4: 72-76. Lesser flamingos which are also called African flamingos live in some of the worlds most extreme aquatic environments. Research on flamingo communication commonly stems from captive studies. As the natural habitats of these types of predators are destroyed by humans, they move where they can for survival. The surface water then pumps into their mouth and goes through a fine filter in their bill. The ability to observe these behaviors at close range allows researchers to observe and assess behaviors that normally could not be observed in the wild.

The lesser flamingo averages weight of between 1.5 and 2.0 kg. Sinclair, I., P. Hockey, W. Tarboton. Larger carnivorous birds instead force lesser flamingos to abandon their nests. Their feeding strategy, feeding in alkaline or saline bodies of water, does not affect other species. Other factors that reduce the lesser flamingos success rates include desertion of newly-hatched eggs, losses of young in the water and mud, and the formation of soda anklets on the legs of chicks. They are very responsive to changes in their environment such as any fluctuations in physical or chemical variables. Downloaded on 19 December 2018.
