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 black-winged stilt, common stilt, or pied stilt (Himantopus himantopus) is a widely distributed very long-legged wader in the avocet and stilt family (Recurvirostridae). Opinions differ as to whether the birds treated under the scientific name H. himantopus ought to be treated as a single species and if not, how many species to recognize. The scientific name Himantopus comes from the Greek meaning "strap foot" or "thong foot". Most sources today accept 2–4 species.
|This section does not cite any references or sources. (March 2013)|
Adults are 33–36 cm long. They have long pink legs, a long thin black bill and are blackish above and white below, with a white head and neck with a varying amount of black. Males have a black back, often with greenish gloss. Females' backs have a brown hue, contrasting with the black remiges. In the populations that have the top of the head normally white at least in winter, females tend to have less black on head and neck all year round, while males often have much black, particularly in summer. This difference is not clear-cut, however, and males usually get all-white heads in winter.
Immature birds are grey instead of black and have a markedly sandy hue on the wings, with light feather fringes appearing as a whitish line in flight.

Taxonomy and systematics
The taxonomy of this bird is still somewhat contentious. Some describe as many as five distinct species; others consider some or all of these to be subspecies. In addition, two dubious subspecies are also sometimes listed, but not as independent species. In the most extensive circumscription, with one species and 5–7 subspecies, this bird is often called common stilt. The name black-winged stilt on the other hand can specifically refer to the Old World nominate subspecies. The commonly accepted taxa are:
- Black-winged stilt proper (Himantopus himantopus himantopus or H. himantopus) (Linnaeus, 1758) – including proposed subspecies meridionalis (S Africa) and ceylonensis (Sri Lanka)
- W Europe and Mediterranean region to Central Asia, sub-Saharan Africa and Madagascar, South and Southeast Asia; localized breeder in East Asia (e.g. Taiwan) but more widespread during winter; has become a regular migrant to the Marianas and Saipan and sometimes is seen on other islands in western Micronesia (e.g. Koror, Ngeriungs Islet and Peleliu of Palau) since the late 20th-century. NW populations migrate south to Africa in winter.
- Head and neck vary from all-white to white with all-black cap and hindneck, usually with white band across upper back. Sometimes vestigial open black chest band.
- Black-necked stilt (Himantopus himantopus mexicanus, Himantopus mexicanus mexicanus or H. mexicanus) (P.L.S.Müller, 1776)
- Southern North America through Central America and Caribbean to N Peru and NE Brazil. Northernmost populations migrate south in winter. Intergrades with white-backed stilt in C Brazil.
- Head and neck always white with black cap down to the eyeline, white spot above eye, black hindneck. Usually no white band across upper back. Often vestigial open black chest band.
- White-backed stilt (Himantopus himantopus melanurus, Himantopus mexicanus melanurus or H. melanurus) (Vieillot, 1817)
- South America from C Peru and N Chile to SE Brazil and south to SC Argentina. Intergrades with black-necked stilt in C Brazil.
- Head and neck usually white with black hindneck and a black line from the nape to the eye. Usually has open black chest band and a white band across upper back.
- White-headed stilt, pied stilt, or (New Zealand) poaka (Himantopus himantopus leucocephalus or H. leucocephalus) (Gould, 1837)
- Java to New Guinea, Australia and New Zealand. Southern population winter in the Philippines region.
- Head usually all-white, neck white, black behind and with open black chest band. Usually a white band across upper back.
- Hawaiian stilt or āeʻo (Himantopus himantopus knudseni, Himantopus mexicanus knudseni or H. knudseni) (Stejneger, 1887)
- Hawaiian Islands, where it is the only breeding shorebird
- Generally similar to black-necked stilt, but black on head and neck more extensive, usually extending below the eye.
Ecology and status
The breeding habitat of all these stilts is marshes, shallow lakes and ponds. Some populations are migratory and move to the ocean coasts in winter; those in warmer regions are generally resident or short-range vagrants. In Europe, the Black-winged Stilt is a regular spring overshoot vagrant north of its normal range, occasionally remaining to breed in northern European countries, for example in Britain in 1987.
These birds pick up their food from sand or water. They mainly eat insects and crustaceans.
The nest site is a bare spot on the ground near water. These birds often nest in small groups, sometimes with avocets.
The Hawaiian population is endangered due to habitat loss and probably also introduced predators. The IUCN recognizes 3 species at present, merging the Hawaiian and South American birds with the Black-necked Stilt; consequently, none of the three is listed as a threatened species. The Black-winged Stilt is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds applies.
