Bee-eater
The bee-eaters are a group of birds in the family (biology), family Meropidae, containing three genera and thirty-one species. Most species are found in Africa and Asia, with a few in southern Europe, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All have long down-turned Beak, bills and medium to long wings, which may be pointed or round. Male and female plumages are usually similar. As their name suggests, bee-eaters predominantly eat flying insects, especially bees and wasps, which are caught on the wing from an open perch. The insect's stinger is removed by repeatedly hitting and rubbing the insect on a hard surface. During this process, pressure is applied to the insect's body, thereby discharging most of the venom. Most bee-eaters are Social animal, gregarious. They form Bird colony, colonies, nesting in burrows tunnelled into vertical sandy banks, often at the side of a river or i ...

European Bee-eater
The European bee-eater (''Merops apiaster'') is a near passerine bird in the bee-eater family, Meropidae. It breeds in southern and central Europe, northern and southern Africa, and western Asia. Except for the resident southern African population, the species is strongly migratory, wintering in tropical Africa. This species occurs as a spring overshoot north of its usual range, with occasional breeding in northern Europe. Taxonomy and systematics The European bee-eater was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Merops apiaster''. The genus name '' Merops'' is Ancient Greek for "bee-eater", and ''apiaster'' is Latin, also meaning "bee-eater", from ''apis'', "bee". Description This species, like other bee-eaters, is a richly coloured, slender bird. It has brown and yellow upper parts, whilst the wings are green and the beak is black. It can reach a length of , incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merops (genus)
''Merops'' is a large genus of bee-eaters, a group of birds in the family (biology), family Meropidae, native to Africa, Asia, Australia and Europe. The members of this family are characterised by richly coloured plumage, slender bodies and usually elongated central tail feathers. They predominantly eat insects, especially bees, wasps and hornets, which are caught in the air. All bee-eaters are in the genus ''Merops'' and subfamily Meropinae except for three Asiatic bearded bee-eaters in the subfamily Nyctyornithinae (in genera ''Nyctyornis'' and ''Meropogon''). The genus ''Merops'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae''. The Type species#Use in zoology, type species is the European bee-eater. The genus name is Ancient Greek for "bee-eater". Taxonomy and systematics Twenty-eight species are recognized: Former species Formerly, some authorities also considered the following ...

Nyctyornis
''Nyctyornis'' is a genus of the bee-eaters, near passerine birds in the family Meropidae. There are just two members of this group, which occur in tropical south and southeastern Asia. The genus ''Nyctyornis'' was introduced by the naturalists William Jardine and Prideaux John Selby in 1830. The name comes from the Ancient Greek ''nukt'' meaning nocturnal or night and ''ornis'' meaning bird. A molecular phylogenetic study published in 2007 showed that the genus is basal and forms a sister group to the remaining members of the bee-eater family. Like other bee-eaters, ''Nyctyornis'' species are colourful birds with long tails, long downturned bills and pointed wings. They are large bee-eaters (blue-bearded is the largest of all bee-eaters), predominantly green, with a face colour as indicated by the species' name. This colour extends on to the slightly hanging throat feathers to form the "beard". The two ''Nyctyornis'' species are the only bee-eaters that lack an eye-stripe ...

Purple-bearded Bee-eater
The purple-bearded bee-eater or Celebes bee-eater (''Meropogon forsteni'') is a near passerine bird in the bee-eater family Meropidae. It is an endemic resident on the island of Sulawesi, Indonesia. This species is often seen in clearings inside dense forest. The purple-bearded bee-eater is the only member of the genus ''Meropogon''. Its scientific name commemorates Eltio Alegondas Forsten (1811–1843) who collected in the East Indies between 1838 and 1842. Description The purple-bearded bee-eater is a colourful long bird with a long tail, long slender decurved beak and rather rounded wings. It is long, excluding of tail streamers. The adult male has a purple head, face, “beard” (long hanging throat feathers), breast and upper belly. The upperparts, wings and tail are green, apart from a reddish-brown nape, and the central tail feathers are elongated as streamers. The lower belly is reddish-brown and the underside of the tail is chestnut. The adult female is similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingfisher
Kingfishers are a family, the Alcedinidae, of small to medium-sized, brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species living in the tropical regions of Africa, Asia, and Oceania, but also can be found in Europe and the Americas. They can be found in deep forests near calm ponds and small rivers. The family contains 118 species and is divided into three subfamilies and 19 genera. All kingfishers have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with only small differences between the sexes. Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey, usually caught by swooping down from a perch. While kingfishers are usually thought to live near rivers and eat fish, many species live away from water and eat small invertebrates. Like other members of their order, they nest in cavit ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently. Females typically have an oviposit ...

Coraciidae
Coraciidae () is a family of Old World birds, which are known as rollers because of the aerial acrobatics some of these birds perform during courtship or territorial flights. The family contains 13 species and is divided into two genera. Rollers resemble crows in size and build, and share the colourful appearance of kingfishers and bee-eaters, blues and pinkish or cinnamon browns predominating. The two inner front toes are connected, but not the outer one. They are mainly insect eaters, with ''Eurystomus'' species taking their prey on the wing, and those of the genus ''Coracias'' diving from a perch to catch food items from on the ground, like giant shrikes. Although living rollers are birds of warm climates in the Old World, fossil records show that rollers were present in North America during the Eocene. They are monogamous and nest in an unlined hole in a tree or in masonry, and lay 2–4 eggs in the tropics, 3–6 at higher latitudes. The eggs, which are white, hatch after 17 ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
