Lesser Flamingo
The lesser flamingo (''Phoeniconaias minor'') is a species of flamingo occurring in sub-Saharan Africa and western India. Birds are occasionally reported from further north, but these are generally considered Vagrancy (biology), vagrants. Characteristics The lesser flamingo is the smallest species of flamingo, though it is a tall and large bird by most standards. The species can weigh from . The standing height is around . The total length (from beak to tail) and wingspan are in the same range of measurements, from . Most of the plumage is pinkish white. The clearest difference between this species and the greater flamingo, the only other Old World species of flamingo, is the much more extensive black on the bill. Size is less helpful unless the species are together, since the sexes of each species also differ in height. The extinct species ''Phoeniconaias proeses'' in the same genus, from the Pliocene of Australia, is thought to have been even smaller. The lesser flamingo may ...

Lake Nakuru
Lake Nakuru is one of the Rift Valley lakes at an elevation of above sea level. It lies to the south of Nakuru, in the rift valley of Kenya and is protected by Lake Nakuru National Park. The lake's abundance of algae used to attract a vast quantity of flamingos that famously lined the shore. Other birds also flourish in the area, as do warthogs, baboons and other large mammals. Eastern black rhinos and southern white rhinos have also been introduced. The lake's level dropped dramatically in the early 1990s but has since largely recovered. In 2013, the lake received an alarming increase in the water levels that led to the migration of flamingos to Lake Bogoria in search for food supply. Between 2010-2020 Lake Nakuru increased in surface area from 40 to 68 square kilometres. 677 households, parts of Nakuru town and National Park areas had been flooded. Nakuru means "Dust or Dusty Place" in the Maasai language. Lake Nakuru National Park, close to Nakuru town, was established in ...

Alkali Soils
Alkali, or Alkaline, soils are clay soils with high pH (greater than 8.5), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swellManaging irrigation water quality, Oregon State University, USA

Lake Natron
Lake Natron is a salt or alkaline lake located in north Ngorongoro District of Arusha Region in Tanzania. It is in the Gregory Rift, which is the eastern branch of the East African Rift. The lake is within the Lake Natron Basin, a Ramsar Site wetland of international significance. The lake is fed principally by the Southern Ewaso Ng'iro River, which rises in central Kenya, and by mineral-rich hot springs. It is quite shallow, less than deep, and varies in width depending on its water level. The lake is a maximum of long and wide. The surrounding area receives irregular seasonal rainfall, mainly between December and May totalling per year. Temperatures at the lake are frequently above . High levels of evaporation have left behind natron (sodium carbonate decahydrate) and trona (sodium sesquicarbonate dihydrate). The alkalinity of the lake can reach a pH of greater than 12. The surrounding bedrock is composed of alkaline, sodium-dominated trachyte lavas that were laid down ...

Corrosive Substance
A corrosive substance is one that will damage or destroy other substances with which it comes into contact by means of a chemical reaction. Etymology The word ''corrosive'' is derived from the Latin verb ''corrodere'', which means ''to gnaw'', indicating how these substances seem to "gnaw" their way through flesh or other materials. Chemical terms The word ''corrosive'' refers to any chemical that will dissolve the structure of an object. They can be acids, oxidizers, or bases. When they come in contact with a surface, the surface deteriorates. The deterioration can happen in minutes, e.g. concentrated hydrochloric acid spilled on skin; or slowly over days or years, e.g. the rusting of iron in a bridge. Sometimes the word ''caustic'' is used as a synonym for ''corrosive'' when referring to the effect on living tissues. At low concentrations, a corrosive substance is called an ''irritant'', and its effect on living tissue is called irritation. At high concentrations, a corro ...

Big Cat
The term "big cat" is typically used to refer to any of the five living members of the genus '' Panthera'', namely the tiger, lion, jaguar, leopard, and snow leopard. Despite enormous differences in size, various cat species are quite similar in both structure and behaviour, with the exception of the cheetah, which significantly stands out from the other big and small cats. All cats are carnivores and some are efficient apex predators. Their native ranges include the Americas, Africa, and Asia; the leopard's range also extends into Europe, specifically in Russia.

Martial Eagle
The martial eagle (''Polemaetus bellicosus'') is a large eagle native to sub-Saharan Africa.Ferguson-Lees & Christie, ''Raptors of the World''. Houghton Mifflin Company (2001), . It is the only member of the genus ''Polemaetus''. A species of the booted eagle subfamily (Aquilinae), it has feathering over its tarsus. One of the largest and most powerful species of booted eagle, it is a fairly opportunistic predator that varies its prey selection between mammals, birds and reptiles. It is one of few eagle species known to hunt primarily from a high soar, by stooping on its quarry.Steyn, P. (1983). ''Birds of prey of southern Africa: Their identification and life histories''. Croom Helm, Beckenham (UK). 1983. An inhabitant of wooded belts of otherwise open savanna, this species has shown a precipitous decline in the last few centuries due to a variety of factors. The martial eagle is one of the most persecuted bird species in the world. Due to its habit of taking livestock and re ...

Hyena
Hyenas, or hyaenas (from Ancient Greek , ), are feliform carnivoran mammals of the family Hyaenidae . With only four extant species (each in its own genus), it is the fifth-smallest family in the Carnivora and one of the smallest in the class Mammalia. Despite their low diversity, hyenas are unique and vital components of most African ecosystems. Although phylogenetically closer to felines and viverrids, as part of suborder Feliformia, hyenas are behaviourally and morphologically similar to canids in several elements due to convergent evolution; both hyenas and canines are non-arboreal, cursorial hunters that catch prey with their teeth rather than claws. Both eat food quickly and may store it, and their calloused feet with large, blunt, nonretractable claws are adapted for running and making sharp turns. However, hyenas' grooming, scent marking, defecation habits, mating and parental behavior are consistent with the behavior of other feliforms. Hyenas feature prominently ...

Jackal
Jackals are medium-sized canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (''Lupulella mesomelas'') and side-striped jackal (''Lupulella adusta'') of sub-Saharan-Africa, and the golden jackal (''Canis aureus'') of south-central Europe and Asia. The African golden wolf (''Canis lupaster'') was also formerly considered as a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. Their ...

African Fish Eagle
The African fish eagle (''Haliaeetus vocifer'') or the African sea eagle, is a large species of eagle found throughout sub-Saharan Africa wherever large bodies of open water with an abundant food supply occur. It is the national bird of Malawi, Namibia, Zambia, and Zimbabwe. As a result of its large range, it is known in many languages. Examples of names include: Vis Arend in Afrikaans, ''nkwazi'' in Chewa, ''aigle pêcheur'' in French, ''hungwe'' in Shona, ''inkwazi'' in isiZulu, and ''ntšhu'' (pronounced "ntjhu") in Northern Sotho. This species may resemble the bald eagle in appearance; though related, the two species occurs on different continents, with the bald eagle being resident in North America. Taxonomy The African fish eagle is a species placed in the genus ''Haliaeetus'' (sea eagles). Its closest relative appears to be the critically endangered Madagascar fish eagle (''H. vociferoides''). Like all sea eagle species pairs, this one consists of a white-headed species (t ...

Baboon
Baboons are primates comprising the genus ''Papio'', one of the 23 genera of Old World monkeys. There are six species of baboon: the hamadryas baboon, the Guinea baboon, the olive baboon, the yellow baboon, the Kinda baboon and the chacma baboon. Each species is native to one of six areas of Africa and the hamadryas baboon is also native to part of the Arabian Peninsula. Baboons are among the largest non-hominoid primates and have existed for at least two million years. Baboons vary in size and weight depending on the species. The smallest, the Kinda baboon, is in length and weighs only , while the largest, the chacma baboon, is up to in length and weighs . All baboons have long, dog-like muzzles, heavy, powerful jaws with sharp canine teeth, close-set eyes, thick fur except on their muzzles, short tails, and nerveless, hairless pads of skin on their protruding buttocks called ischial callosities that provide for sitting comfort. Male hamadryas baboons have large white man ...
