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.

In Europe, the habitat includes freshwater lakes, deltas, marshes, or swamps; that is, wherever sufficient amounts of reedbeds or grasses exist for nesting. In Africa, the habitat includes lowlands and alkaline or freshwater lakes. This pelican's fishing technique demands shallow, warm water.
Terrestrial Biomes: savanna or grassland
Aquatic Biomes: lakes and ponds; rivers and streams; coastal
Habitat and Ecology
Mainly larger fresh water bodies
Movements and dispersal
Primarily eats fish. In Europe, prefers carp; in Africa, prefers cichlids. Large fish make up 90% of the Great White Pelican diet. The other 10% includes abundant small fish, and, in SW Africa, eggs and chicks of the Cape Cormorant (Phalacrocorax capensis). Estimated daily food requirement of 900-1200 grams (or 2-4 large fish). Feeds in groups, often cooperatively--this is rare among birds. In cooperative feeding, 8-12 pelicans get in a horseshoe formation on the water; they surround and force fish into shallow water, flapping wings and plunging bills to catch the fish along the way. When it catches a fish, the pelican tilts its bill up and swallows the fish whole.
Life History and Behavior
Perception Channels: visual ; tactile ; acoustic ; chemical
Status: captivity: 51.0 years.
Lifespan, longevity, and ageing
Breeding occurs in spring in temperate zones of Europe; all year round in Africa. This pelican breeds as it lives, in a large colony near water. Male courting behavior includes a display of vivid colors on the gular pouch and a moulted crest. Pair formation, nest site selection, and nest building occurs rapidly (few hours to no more than a week). The nest is on the ground and consists of either a pile of sticks or little more than bare rock. This pelican averages two eggs; incubation of 29-36 days; fledging at 65-75 days. Breeding success rate of .64 chicks per attempt. Sexual maturity at 3-4 years.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous
Evolution and Systematics
V-formation flight of great white pelicans conserves energy by each bird taking advantage of the upwake field made by the wings of the bird in front of them.
"Our results provide empirical evidence that, compared with solo flight, formation flight confers a significant aerodynamic advantage which allows birds [great white pelicans, Pelecanus onocrotalus] to reduce their energy expenditure while flying at a similar speed. In birds flying in formation, each wing moves in an upwash field that is generated by the wings of the other birds in the formation. Modelling has shown that when birds are flying with optimal spacing, a maximal reduction in power can be achieved and total transport costs can be substantially reduced. However, field observations of V formations indicate that birds often shift from their optimal positioning, perhaps in an attempt to maximize the aerodynamic advantage of flight formation, thus reducing the energy saving— so geese, for example, may make an energy saving of only 2.4%.
"In our study, pelicans often had difficulty staying within the formation, particularly when flying at the rear. But even though these birds were regularly adjusting their position, they still achieved a significant energy saving. This saving may be only partly due to effects of the wakes of other birds on the power input that results from formation flight itself. When flying in formation, pelicans appear to beat their wings less frequently and to glide for longer periods. A rough calculation based on our estimates of the proportion of time spent flapping and gliding in formation, and assuming that the overall costs of the glide–flap sequence is the sum of the gliding and flapping components, reveals an actual saving of 1.7–3.4% as a result of wake effects on power input — this value is comparable to that estimated for geese.
"The main benefit of flight formation, which until now has not been recognized, could be that by flying in a vortex wake, pelicans are able to glide for a greater proportion of their total flight time, with the total energy savings of 11.4–14.0% being achieved primarily through this strategy."

Relevance to Humans and Ecosystems
May eat some commercially important fish, but generally this pelican eats non-commercial fish such as shoalfish and cichlids.
Pouch has been used for tobacco pouches and sheaths. Young pelicans are prized for fat; the oils derived from pelican fat are used for medicine in China and India (to fight rheumatism).
Pelican feathers and skin are used to make leather. Excrement makes for good, cheap fertilizer in third world countries.
Great white pelican
The great white pelican (Pelecanus onocrotalus) also known as the eastern white pelican, rosy pelican or white pelican is a bird in the pelican family. It breeds from southeastern Europe through Asia and in Africa in swamps and shallow lakes.
The great white pelican is a huge bird, with only the Dalmatian pelican averaging larger amongst the pelicans. The wingspan can range from 226 to 360 cm (7.41 to 11.81 ft), with the latter measurement the largest recorded among extant flying animals outside of the great albatrosses. The total length of the great white pelican can range from 140 to 180 cm (55 to 71 in), with the enormous bill comprising 28.9 to 47.1 cm (11.4 to 18.5 in) of that length. Adult males, weigh from 9 to 15 kg (20 to 33 lb), though large races from the Palaearctic are usually around 11 kg (24 lb) with few exceeding 13 kg (29 lb). Females are considerably less bulky and heavy, weighing from 5.4 to 9 kg (12 to 20 lb). Among standard measurements, the wing chord length is 60 to 73 cm (24 to 29 in), the tail is 16 to 21 cm (6.3 to 8.3 in) and the tarsus is 13 to 14.9 cm (5.1 to 5.9 in). The standard measurements from differing areas indicate that pelicans of the species from the Western Palaearctic are somewhat larger in size than ones that reside in Asia and in Africa.
Immature great white pelicans are grey and have dark flight feathers. In flight, it is an elegant soaring bird, with the head held close to and aligned with the body by a downward bend in the neck. In breeding condition the male has pinkish skin on its face and the female has orangey skin. It differs from the Dalmatian pelican by its pure white, rather than greyish-white, plumage, a bare pink facial patch around the eye and pinkish legs. Males are larger than females, and have a long beak that grows in a downwards arc, as opposed to the shorter, straighter beak of the female. The spot-billed pelican of Asia is slightly smaller than the great white, with clear brownish-grey plumage and a paler, duller-colored bill. Similarly, the pink-backed pelican is smaller with brownish-grey plumage, with a light pink to off-grey bill and a pinkish wash to the back.
The great white pelican is well adapted for aquatic life. The short strong legs and webbed feet propel it in water and aid the rather awkward takeoff from the water surface. Once aloft, the long-winged pelicans are powerful fliers, however, and often travel in spectacular V-formation groups.
Distribution and habitat
Great white pelicans are usually birds found in and around shallow, (seasonally or tropical) warm fresh water. Well scattered groups of breeding pelicans occur through Eurasia from the eastern Mediterranean to Vietnam. In Eurasia, fresh or brackish waters may be inhabited and the pelicans may be found in lakes, deltas, lagoons and marshes, usually with dense reed beds nearby for nesting purposes. Additionally, sedentary populations are found year-round in Africa, south of the Sahara Desert although these are patchy. In Africa, great white pelicans occur mainly around freshwater and alkaline lakes and may also be found in coastal, estuarine areas. Beyond reed beds, African pelicans have nested on inselbergs and flat inshore islands off of Banc d'Arguin National Park. Migratory populations are found from Eastern Europe to Kazakhstan during the breeding season. More than 50% of Eurasian great white pelicans breed in the Danube Delta in Romania. They like to stay also in the Lakes near Burgas, Bulgaria and in Srebarna Lake in Bulgaria. The pelicans arrive in the Danube in late March or early April and depart after breeding from September to late November. Wintering locations for European pelicans are not exactly known but wintering birds may occur in northeastern Africa through Iraq to north India, with a particularly large number of breeders from Asia wintering around Pakistan. These are birds that are found mostly in lowlands, though in East Africa and Nepal may be found living at elevations of up to 1,372 m (4,501 ft).
The diet of the great white pelican consists mainly of fish. The pelicans leave their roost to feed early in the mornings and may fly over 100 km (62 mi) in search of food, as has been observed in Chad and Mogode, Cameroon. Each pelican needs from 0.9 to 1.4 kg (2.0 to 3.1 lb) of fish every day. This corresponds to around 28,000,000 kg (62,000,000 lb) of fish consumed every year at the largest colony of great white pelicans, on Tanzania's Lake Rukwa, with almost 75,000 birds. Fish targeted are usually fairly large ones, in the 500–600 g (1.1–1.3 lb) weight range, and are taken based on regional abundance. Common carp are preferred in Europe, mullet are preferred in China and Aphanius dispar (a carp) are preferred in India. In Africa, often the commonest cichlids, including many species in the Haplochromis and Tilapia genera, seem to be preferred. The pelican's pouch serves simply as a scoop. As the pelican pushes its bill underwater, the lower bill bows out, creating a large pouch which fills with water and fish. As the bird lifts its head, the pouch contracts, forcing out the water but retaining the fish. A group of 6 to 8 great white pelicans will gather in a horseshoe formation in the water to feed together. They dip their bills in unison, creating a circle of open pouches, ready to trap every fish in the area. Most feeding is cooperative and done in groups, especially in shallow waters where fish schools can be corralled easily, though these pelicans may forage alone as well.
Pelicans are not restricted to fish, however, and are often opportunistic foragers. In some situations they eat chicks of other birds, such as the well documented case off the southwest coast of South Africa. Here, breeding Pelicans from the Dassen Island colony predate chicks weighing up to 2 kg (4.4 lb) from the Cape gannet colony on Malgas Island. Similarly, in Walvis Bay, Namibia the eggs and chicks of Cape cormorants are fed regularly to young pelicans. The local pelican population is so reliant on the cormorants, that when the cormorant species experienced a population decline, the numbers of pelicans appeared to decline as well. Great white pelicans also eat crustaceans, tadpoles and even turtles. They readily accept handouts from humans, and a number of unusual items have been recorded in their diet. During periods of starvation, pelicans also eat seagulls and ducklings. The gulls are held under water and drowned before being eaten headfirst. Pelicans will also rob other birds of their prey.
The breeding season commences in April or May in temperate zones, essentially all year around in Africa and begins in February through April in India. Large numbers of these pelicans breed together in colonies. The female can lay from 1 to 4 eggs in a clutch, with two being the average. Nest locations are variable. Some populations making stick nests in trees but a majority, including all those who breed in Africa, nest exclusively in scrapes on the ground lined with grass, sticks, feathers and other material. The young are cared for by both parents. The incubation stage lasts for 29 to 36 days. The chicks are naked when they hatch but quickly sprout blackish-brown down. The colony gathers in "pods" around 20 to 25 days after the eggs hatch. The young fledge at 65 to 75 days of age. Around 64% of young successful reach adulthood, with sexual maturity attained at 3 to 4 years of age. White pelicans are often protected from bird-eating raptors by virtue of their own great size, but eagles, especially sympatric Haliaeetus species, may predate their eggs, nestlings and fledgings. Occasionally, pelicans and their young are attacked at their colonies by mammalian carnivores from jackals to lions. As is common in pelicans, the close approach of a large predaceous or unknown mammal, including a human, at a colony will lead the pelican to abandon their nest in self-preservation. Additionally, crocodiles, especially Nile crocodiles in Africa, will readily kill and eat swimming pelicans.
Relationships with humans
Today, because of overfishing in certain areas, white pelicans are forced to fly long distances to find food. Great white pelicans are exploited for many reasons. Their pouch is used to make tobacco bags, Their skin is turned into leather, the guano is used as fertiliser, and the fat of young pelicans is converted into oils for traditional medicine in China and India. In Ethiopia, great white pelicans are shot for their meat. Human disturbance, loss of foraging habitat and breeding sites, and pollution are all contributing to the decline of the great white pelican. Declines have been particularly notable in the Palearctic.
The great white pelican is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The great white pelican is classified as Least Concern on the IUCN Red List and is listed on Appendices I and II of the Convention on Migratory Species. It is listed on Appendix II of the Berne Convention on the Conservation of European Wildlife and Natural Habitats and on Annex I of the EC Birds Directive. Overall, though, the great white pelican is still the most widely distributed species. Although some areas still hold quite large colonies, it ranks behind the brown pelican and possibly the Australian pelican in overall abundance. Europe now holds an estimated 7,345–10,000 breeding pairs, with over 4,000 pairs that are known to nest in Russia. During migration, more than 75,000 have been observed in Israel and, in winter, over 45,000 may stay in Pakistan. In all its colonies combined, 75,000 pairs are estimated to nest on the African continent.
This species is often kept in captivity, in zoos or in semi-wild colonies such as that in St. James's Park, London. The ancestors of this colony were originally given to Charles II by the Russian Ambassador in 1664 which initiated the tradition of ambassadors donating the birds.
