Zambezian Halophytics Habitat
The Makgadikgadi spiny agama (Agama hispida makarikarika) is endemic to the Makgadikgadi Pans complex within the Botswana element of the Zambezian halophytics ecoregion. This agama typically inhabits the edges of the pans but it is difficult to spot, since it buries itself in the sand during the heat of the day.
One of the largest saltpans in the world, the Makgadikgadi Pan complex in Botswana stretches out over 12,000 square kilometres. The ecoregion is classified within the Flooded Grasslands and Savanna biome. Surrounded by the semi-arid Kalahari savannas, the pans experience a harsh climate, hot with little rain, and are normally a vast, glaring expanse of salt-saturated clay. These pans are sustained by freshwater from the Nata River, and more infrequently, from input from the Okavango Alluvial Fan by way of the Boteti River. Saline- and drought-tolerant plant species generally line the pan perimeters, with grasslands further removed from the pans.
For most of the year the pans are depauperate in bird numbers, except for ostriches and species such as the Chestnut-banded sand-plover and Kittlitz’s plover (Charadrius pallidus, C. pecuarius). The sole hospitable area to birds during these times is the Nata Delta, which has a permanent water source and a small resident population of waterbirds including grebes (Podiceps spp.), cormorants (Phalacrocorax spp.), ducks and plovers (Charadrius spp.) with a few flamingos (Phoenicopterus ruber, Phoeniconaias minor) and pelicans (Pelecanus spp.). The grasslands surrounding the pans support a moderate bird fauna with species such as ostriches, secretary birds (Sagittarius serpentarius), kori bustards (Ardeotis kori), korhaans (Eupodotis spp.), sandgrouse (Pterocles spp.) and francolin (Francolinus spp.) being common. The Hyphaene palms to the west of the pans are nesting sites for, among others, the greater kestrel (Falco rupicoloides) and the palm-nut vulture (Gypohierax angolensis). After good rains the pans are transformed into a vibrant paradise, attracting thousands of waterbirds, most of which come to breed on the pans. Wattled and southern crowned cranes (Grus carunculatus, Balearica regulorum), saddle-billed, marabou and open-billed storks (Ephippiorhynchus senegalensis, Leptoptilos crumeniferus, Anastomus lamelligerus), African fish eagles (Haliaeeetus vocifer), black-necked grebes (Podiceps nigricollis), Caspian terns (Hydroprogne caspia), eastern white and pink-backed pelicans (Pelecanus onocrotalus, P. rufescens), geese and waders such as avocets (Recurvirostra avosetta), black-winged stilts (Himantopus himantopus), plovers, sandpipers and teals (Anas spp.) congregate around the pans. The most spectacular arrival are the greater and lesser flamingos (Phoenicopterus ruber and Phoeniconaias minor) that flock to the pans in their thousands.
Most mammalian taxa within the ecoregion inhabit the grasslands surrounding the pans. These include Hartebeest (Alcelaphus buselaphus), Gemsbok (Oryx gazella), Springbok (Antidorcas marsupialis), Steenbok (Raphicerus campestris), Greater kudu (Tragelaphus strepsiceros), Giraffe (Giraffa camelopardus), Burchells zebra (Equus burchelli), Blue wildebeest (Connocheatus taurinus), black-backed jackal (Canis mesomelas), Brown hyaena (Hyaena brunnea), Spotted hyaena (Crocuta crocuta), Lion (Panthera leo), Cheetah (Acinonyx jubatus), Painted hunting dog (Lycaon pictus) and even African bush elephant (Loxodonta africana) along the Boteti River. The Nxai Pan has a sizeable Springbok population and is one of the few places where Springbok and Impala cohabit. These two antelope are normally separated by habitat preference, but the Acacia savanna surrounding Nxai Pan provides the impala with a suitable habitat while the grass covered pan mimics the desert conditions preferred by Springbok.

The saddle-billed stork (Ephippiorhynchus senegalensis) is a large wading bird in the stork family, Ciconiidae. It is a widespread species which is a resident breeder in sub-Saharan Africa from Sudan, Ethiopia and Kenya south to South Africa, and in The Gambia, Senegal, Côte d'Ivoire and Chad in west Africa.
This is a close relative of the widespread Asian black-necked stork, the only other member of the genus Ephippiorhynchus.
This is a huge bird that regularly attains a height of 150 cm (59 in), a length of 142 cm (56 in) and a 2.4–2.7 m (7.9–8.9 ft) wingspan. The male is larger and heavier than the female, with a range of 5.1–7.52 kg (11.2–16.6 lb), with a mean mass of 6.38 kg (14.1 lb). The female is usually between 5 and 6.84 kg (11.0 and 15.1 lb), wit a mean mass of 5.95 kg (13.1 lb). It is probably the tallest of the storks (though not the heaviest), due in no small part to it extremely long legs (tarsus length is up to 36.5 cm (14.4 in)). The long bill measures from 27.3 to 36 cm (10.7 to 14.2 in). The sexes can be readily distinguished by the golden yellow irises of the female and the brown irises and dangling yellow wattles of the male.
It is spectacularly plumaged, identical in male and female when perched but the female shows much more white in the primaries in flight. The head, neck, back, wings, and tail are iridescent black, with the rest of the body and the primary flight feathers being white. Juveniles are browner grey in plumage. The massive bill is red with a black band and a yellow frontal shield (the "saddle"). The legs and feet are black with pink hocks. On the chest is a bare red patch of skin, whose colour darkens during breeding season.
They are silent except for bill-clattering at the nest. Like most storks, these fly with the neck outstretched, not retracted like a heron; in flight, the large heavy bill is kept drooping somewhat below belly height, giving these birds a very unusual appearance to those who see them for the first time. To experienced birdwatchers on the other hand, this makes them easily recognizable even if seen from a distance. It has been suggested that due to the large size and unusual appearance in flight, this species is the basis for the "big bird" and kongamato cryptids.
The saddle-billed stork breeds in forested waterlands and other floodlands in tropical lowland. It builds a large, deep stick nest in a tree, laying one or two white eggs weighing about 146 g each. It does not form breeding colonies, and is usually found alone or in pairs. The incubation period is 30–35 days, with another 70 – 100 days before the chicks fledge.
Food and feeding
The saddle-billed stork, like most of its relatives, feeds mainly on fish, frogs and crabs, but also on small birds and reptiles. They move in a deliberate and stately manner as they hunt, in a similar way to the larger herons.
Relation to Ancient Egyptian culture
[dubious ] Its description is often erroneously given as "jabiru", which is actually this species' Latin American relative. The Third Dynasty pharaoh Khaba incorporated this hieroglyph in his name (Jiménez Serrano 2002).
