African Scops-owl
The African scops owl (''Otus senegalensis'') is a small owl which is widespread in sub-Saharan Africa. Taxonomy William John Swainson first described the species in 1837 from a specimen collected in Senegal, and initially assigned it to the now defunct genus ''Scops''. Today the species is assigned to the genus ''Otus''. There are three subspecies currently recognised: *''Otus senegalensis senegalensis'': Widespread in sub-Saharan Africa *''Otus senegalensis nivosus'': Found in south-eastern Kenya from the lower Tana River to the Lali Hills *''Otus senegalensis feae'': Endemic to Annobón island in the Gulf of Guinea (regarded by Birdlife International as a separate species, the Annobón scops owl) The African scops owl was formerly regarded as the African subspecies of the scops owl. It was grouped with the Arabian scops owl, Socotra scops owl, and the Annobón scops owl into ''Otus senegalensis''; however, these species are now considered to be separate. Descriptio ...

Lake Baringo
Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of and an elevation of . The lake is fed by several rivers: the Molo, Perkerra and Ol Arabel. It has no obvious outlet; the waters are assumed to seep through lake sediments into the faulted volcanic bedrock. It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha. See "Kenya designates freshwater lake in Great Rift Valley," aRamsar 2009 - 2002 The lake is in a remote hot and dusty area with over 470 species of birds, occasionally including migrating flamingos. A Goliath heronry is located on a rocky islet in the lake known as Gibraltar. Description The lake is part of the East African Rift system. The Tugen Hills, an uplifted fault block of volcanic and metamorphic rocks, lies west of the lake. The Laikipia Escarpment lies to the east. Water flows into the lake from the Mau Hills and Tugen Hills. It is a critical habitat a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socotra Scops Owl
The Socotra scops owl (''Otus socotranus'') is a small owl endemic to the island of Socotra, Yemen. Taxonomy The Socotra scops owl was previously lumped with the African scops owl (''Otus senegalensis''), but differences in plumage and vocalisations have led to it being split to a separate species. Recent genetic research suggests that its closest relatives are the Oriental scops owl and the Seychelles scops owl (''Otus insularis''). An interesting theory this research has led to is that the oriental scops owl is a taxon that evolved from a colonisation of the continent from island ancestors, an event which had previously been thought unlikely because island taxa were thought to be less competitive than related continental taxa. Description A very small scops owl which is heavily streaked and barred on its pale sandy-grey upperparts, paler underparts with darker shaft streaks and fine, dark barring. The plain facial disc has vague margins and the shoulder stripe is not as conspi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owls Of Sub-Saharan Africa
Owls are birds from the order Strigiformes (), which includes over 200 species of mostly solitary and nocturnal birds of prey typified by an upright stance, a large, broad head, binocular vision, binaural hearing, sharp talons, and feathers adapted for silent flight. Exceptions include the diurnal northern hawk-owl and the gregarious burrowing owl. Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands. Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn-owl family, Tytonidae. A group of owls is called a "parliament". Anatomy Owls possess large, forward-facing eyes and ear-holes, a hawk-like beak, a flat face, and usually a conspicuous circle of feathers, a facial disc, around each eye. The feathers making up this disc can be adjusted to sharply focus sounds from varying distances onto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Africa
This is a list of the bird species recorded in Africa. The area covered by this list is the Africa region defined by the American Birding Association's listing rules.

Otus (bird)
Scops owls are typical owls in family Strigidae belonging to the genus ''Otus'' and are restricted to the Old World. ''Otus'' is the largest genus of owls with 59 species. Scops owls are colored in various brownish hues, sometimes with a lighter underside and/or face, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a greyish- and a reddish-brown morph. They are small and agile, with both sexes being compact in size and shape. Female scops owls are usually larger than males. For most of the 20th century, this genus included the American screech owls, which are now again separated in ''Megascops'' based on a range of behavioral, biogeographical, morphological and DNA sequence data. Taxonomy The genus ''Otus'' was introduced in 1769 by the Welsh naturalist Thomas Pennant for the Indian scops owl (''O. bakkamoena''). The name is derived from the Latin word ' and the Greek word ''ōtos'' meaning horned or eared owl (cf. οὖς, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his s ...

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995. The Lepidoptera: Form, function and diversity. Oxford, UK: Oxford University Press; 404 p. Although the rules for distinguishing moths from butterflies are not well establishe ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under ...
