Lizard Buzzard
The lizard buzzard (''Kaupifalco monogrammicus'') or lizard hawk, is a bird of prey in the family Accipitridae. It is native to Sub-Saharan Africa. Despite its name, it may be more closely related to the ''Accipiter'' hawks than the ''Buteo'' buzzards. Taxonomy Molecular phylogenetic studies have revealed that the lizard buzzard is not closely related to ''Buteo'' buzzards but rather to ''Accipiter'' hawks. This extends to morphological associations, e.g. the lizard buzzard has pointed and fairly short wings. Despite the lizard buzzard inhabiting Africa, phylogenetic evidence indicates that its closest relatives are the two ''Microspizias'' hawks of Central and South America.'''' Description The lizard buzzard is a smallish stocky raptor with a total body length of 35–37 cm and a wingspan of about 79 cm. Males weigh 246 g, females 304 g on average. The upperparts, head and breast are grey. There is a vertical black line on the white throat, which distinguishes this ...

Senegal
Senegal,; Wolof: ''Senegaal''; Pulaar: 𞤅𞤫𞤲𞤫𞤺𞤢𞥄𞤤𞤭 (Senegaali); Arabic: السنغال ''As-Sinighal'') officially the Republic of Senegal,; Wolof: ''Réewum Senegaal''; Pulaar : 𞤈𞤫𞤲𞤣𞤢𞥄𞤲𞤣𞤭 𞤅𞤫𞤲𞤫𞤺𞤢𞥄𞤤𞤭 (Renndaandi Senegaali); Arabic: جمهورية السنغال ''Jumhuriat As-Sinighal'') is a country in West Africa, on the Atlantic Ocean coastline. Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds the Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar. Senegal is notably the westernmost country in the mainland of the Old World, or Afro-Eurasia. It owes its name to the ...

Yellow-billed Kite
The yellow-billed kite (''Milvus aegyptius'') is the Afrotropic counterpart of the black kite (''Milvus migrans''), of which it is most often considered a subspecies. However, DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species. Taxonomy The yellow-billed kite was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He specified that the bird was found in Egypt, placed it with the eagles, falcons and relatives in the genus '' Falco'' and coined the binomial name ''Falco aegyptius''. Unusually Gmelin did not cite a source for his information. The yellow-billed kite is now one of three kites placed in the genus ''Milvus'' that was introduced in 1799 by the French naturalist Bernard Germain de Lacépède. There are two subspecies: ''M. a. parasitus'' ( Daudin, 1800) , ...

Lesser Kestrel
The lesser kestrel (''Falco naumanni'') is a small falcon. This species breeds from the Mediterranean across Afghanistan and Central Asia, to China and Mongolia. It is a summer bird migration, migrant, wintering in Africa and Pakistan and sometimes even to India and Iraq. It is rare north of its breeding range, and declining in its European range. The genus name derives from Late Latin ''falx'', ''falcis'', a sickle, referencing the claws of the bird, and the species name commemorates the German naturalist Johann Friedrich Naumann. Description It is a small bird of prey, in length with a wingspan. It looks very much like the larger common kestrel but has proportionally shorter wings and tail. It shares a brown back and barred grey underparts with the larger species. The male has a grey head and tail like male common kestrels, but lacks the dark spotting on the back, the black Cheek, malar stripe, and has grey patches in the wings. The female and young birds are slightly paler ...

Steppe Buzzard
The common buzzard (''Buteo buteo'') is a medium-to-large bird of prey which has a large range. A member of the genus ''Buteo'', it is a member of the family Accipitridae. The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (Tian Shan), far western Siberia and northwestern Mongolia.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt. Over much of its range, it is a year-round resident. However, buzzards from the colder parts of the Northern Hemisphere as well as those that breed in the eastern part of their range typically migrate south for the northern winter, many journeying as far as South Africa.Bildstein, K. L., & Zalles, J. I. (2005). ''Old World versus New World long-distance migration in accipiters, buteos, and falcons''. Birds of two worlds: the ecology and evolution of migration.

Hooded Vulture
The hooded vulture (''Necrosyrtes monachus'') is an Old World vulture in the order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus ''Necrosyrtes,'' which is sister to the larger ''Gyps'' genus, both of which are a part of the Aegypiinae subfamily of Old World vultures. It is native to sub-Saharan Africa, where it has a widespread distribution with populations in southern, East and West Africa. It is a scruffy-looking, small vulture with dark brown plumage, a long thin bill, bare crown, face and fore-neck, and a downy nape and hind-neck. Its face is usually a light red colour. It typically scavenges on carcasses of wildlife and domestic animals. Although it remains a common species with a stable population in the lower region of Casamance, some areas of The Gambia, and Guinea-Bissau, other regions such as Dakar, Senegal, show more than 85% losses in population over the last 50 years. Threats include poisoning, hunting, l ...

Black Kite
The black kite (''Milvus migrans'') is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. Current global population estimates run up to 6 million individuals. Unlike others of the group, black kites are opportunistic hunters and are more likely to scavenge. They spend much time soaring and gliding in thermals in search of food. Their angled wing and distinctive forked tail make them easy to identify. They are also vociferous with a shrill whinnying call. The black kite is widely distributed through the temperate and tropical parts of Eurasia and parts of Australasia and Oceania, with the temperate region populations tending to be migratory. Several subspecies are recognized and formerly had their own English names. The European populations are small, but the South Asian popula ...

Grasshopper Buzzard
The grasshopper buzzard (''Butastur rufipennis'') is a species of bird of prey in the family Accipitridae which is found in a narrow zone of sub-Saharan Africa north of the equator. Taxonomy The grasshopper buzzard forms a superspecies with the white-eyed buzzard (''Butastur teesa''), rufous-winged buzzard (''Butastur liventer''), and grey-faced buzzard (''Butastur indicus'') all of which occur in Asia. Description The adult grasshopper buzzard is grey brown above with a darker head and dark shaft streaks on all of its feathers. The feathers of the mantle and lesser coverts are narrowly with fringed rufous in fresh plumage, although this wears off. The grey tail has faint brown bars. The greater coverts and primary feathers are light rufous, the primaries are tipped with black, and form a conspicuous reddish patch in flight. The secondary feathers are rufous shading to dark brown towards the tip, which is white. The chin and throat are whitish, with three black streaks on e ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Biodiversity Loss
Biodiversity loss includes the worldwide extinction of different species, as well as the local reduction or loss of species in a certain habitat, resulting in a loss of biological diversity. The latter phenomenon can be temporary or permanent, depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration/ecological resilience or effectively permanent (e.g. through land loss). The current global extinction (frequently called the sixth mass extinction or Anthropocene extinction), has resulted in a biodiversity crisis being driven by human activities which push beyond the planetary boundaries and so far has proven irreversible. Even though permanent global species loss is a more dramatic and tragic phenomenon than regional changes in species composition, even minor changes from a healthy stable state can have dramatic influence on the food web and the food chain insofar as reductions in only one species can adversely affect th ...

Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined some ...

Saloum Delta National Park
Saloum Delta National Park or Parc National du Delta du Saloum in Senegal, is a national park. Established in 1976, it is situated within the Saloum Delta at the juncture of the Saloum River and the North Atlantic. The park, which forms part of a UNESCO World Heritage Site and a Ramsar Convention site, lies within a biosphere reserve. Water comprises of the park, intertidal mangroves and saltwater vegetation cover , and savannah and forest cover . It lies on the East Atlantic Flyway. The bird species that breed or winter in the area include royal tern, greater flamingo, Eurasian spoonbill, curlew sandpiper, ruddy turnstone, and little stint. This region represents an important synergy between nature with extensive biodiversity and the way of human development, which is still present, albeit fragile. Sustainable shellfish farming is highly developed here and is a very important source of food and export revenue for the local community and Senegal in general. The Saloum Delta ...
