Storks
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 19 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ansch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Painted Stork
The painted stork (''Mycteria leucocephala'') is a large wading bird, wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink Flight feather#Tertials, tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not bird migration, migratory and only make short distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycteria
''Mycteria'' is a genus of large tropical storks with representatives in the Americas, east Africa and southern and southeastern Asia. Two species have " ibis" in their scientific or old common names, but they are not related to these birds and simply look more similar to an ibis than do other storks. The ''Mycteria'' storks are large birds, typically around 90–100 cm in length with a 150 cm wingspan. The body plumage is mainly white in all the species, with black in the flight feathers of the wings. The Old World species have a bright yellow bill, red or yellow bare facial skin and red legs, but these parts are much duller in the wood stork of tropical America. Juvenile birds are a duller version of the adult, generally browner, and with a paler bill. They are gregarious broad-winged soaring birds that fly with the neck outstretched and legs extended. They are resident breeders in lowland wetlands with trees in which they build large stick nests. Most specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciconia
__NOTOC__ ''Ciconia'' ( ; ) is a genus of birds in the stork family. Six of the seven living species occur in the Old World, but the maguari stork has a South American range. In addition, fossils suggest that ''Ciconia'' storks were somewhat more common in the tropical Americas in prehistoric times. The genus was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the white stork (''Ciconia ciconia'') as the type species. The genus name is the Latin word for "stork", and was originally recorded in the works of Horace and Ovid. The Abdim's stork is the smallest of the family, but other species in the genus are generally medium-sized storks, with long legs and a long thick bill. The members of this genus are more variable in plumage than other stork genera, but all species are black (at least to the wings) and white (at least underparts or neck). Juveniles are a duller, browner version of the adult. Depending on species, breeding can be in solitary pairs or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anastomus
The openbill storks or openbills are two species of stork (family '' Ciconiidae'') in the genus ''Anastomus''. They are large wading birds characterized by large bills, the mandibles of which do not meet except at the tip. This feature develops only in the adults. Both species feed predominantly on molluscs. The roof of the upper bill is fringed with plate-like structures ("lamellae") in the African openbill, but these are absent in the Asian openbill. The genus ''Anastomus'' was erected by the French naturalist Pierre Bonnaterre in 1791. The type species was subsequently designated as the Asian openbill (''Anastomus oscitans''). The name ''Anastomus'' is from the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic peri ... αναστομοω ''anastomoō'' meaning "to furnis ...

Jabiru
The jabiru ( or ; ''Jabiru mycteria'') is a large stork found in the Americas from Mexico to Argentina, except west of the Andes. It sometimes wanders into the United States, usually in Texas, but has been reported as far north as Mississippi. It is most common in the Pantanal region of Brazil and the Eastern Chaco region of Paraguay. It is the only member of the genus ''Jabiru''. The name comes from a Tupi–Guaraní language and means "swollen neck". Taxonomy Hinrich Lichtenstein described the jabiru in 1819. The name ''jabiru'' has also been used for two other birds of a distinct genus: black-necked stork (''Ephippiorhynchus asiaticus''), commonly called "jabiru" in Australia; and sometimes also for the saddle-billed stork (''Ephippiorhynchus senegalensis'') of Sub-Saharan Africa. In particular, Gardiner's Egyptian hieroglyph G29, believed to depict an ''E. senegalensis'', is sometimes labeled "jabiru" in hieroglyph lists. The ''Ephippiorhynchus'' are believed to be the ...

Leptoptilos
''Leptoptilos'' is a genus of very large tropical storks, also known as the adjutant bird. The name means thin (''lepto'') feather (''ptilos''). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa. These are huge birds, typically 110–150 cm tall with a 210–250 cm wingspan. The three species each have a black upper body and wings, and white belly and undertail. The head and neck are bare like those of a vulture. The huge bill is long and thick. Juveniles are a duller, browner version of the adult. ''Leptoptilos'' storks are gregarious colonial breeders in wetlands, building large stick nests in trees. They feed on frogs, insects, young birds, lizards and rodents. They are frequent scavengers, and the naked head and neck are adaptations to this, as are those of the vultures with which they often feed. A feathered head would become rapidly clotted with blood and other substances when a scavenging bird's head wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephippiorhynchus
'' Ephippiorhynchus'' is a small genus of storks. It contains two living species only, very large birds more than 140 cm tall with a 230–270 cm wingspan. Both are mainly black and white, with huge bills. The sexes of these species are similarly plumaged, but the eyes are dark brown in males and yellow in females. The members of this genus are sometimes called "jabirus", but this properly refers to a close relative from Latin America. These large wading birds breed in marshes and other wetlands, building a large, deep stick nest in a tree. Like most storks, they fly with the neck outstretched, not retracted like a heron; in flight, they present a strange shape, with the head and large bill somewhat drooping down. They are silent except for bill-clattering at the nest. '' Ephippiorhynchus'' storks, like most of their relatives, feeds mainly on fish, frogs and crabs, but also on young birds, and other land vertebrates. They move in a deliberate and stately manner as they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Early Oligocene
The Rupelian is, in the geologic timescale, the older of two ages or the lower of two stages of the Oligocene Epoch/Series. It spans the time between . It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian Stage. Name The stage is named after the small river Rupel in Belgium, a tributary to the Scheldt. The Belgian Rupel Group derives its name from the same source. The name Rupelian was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The separation between the group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphic and chronostratigraphic names. Stratigraphic definition The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the extinction of the foraminiferan genus ''Hantkenina''. An official GSSP for the base of the Rupelian has been assigned in 1992 (Massignano, Italy). The transi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
