Hoopoe
Hoopoes () are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "crown" of feathers. Three living and one extinct species are recognized, though for many years all of the extant species were lumped as a single species—''Upupa epops''. In fact, some taxonomists still consider all three species conspecific. Some authorities also keep the African and Eurasian hoopoe together but split the Madagascar hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on The IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round. Taxonomy The genus ''Upupa'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The type species is the ...

Eurasian Hoopoe
The Eurasian hoopoe (''Upupa epops'') is the most widespread species of the genus '' Upupa''. It is a distinctive cinnamon coloured bird with black and white wings, a tall erectile crest, a broad white band across a black tail, and a long narrow downcurved bill. Its call is a soft "oop-oop-oop". It is native to Europe, Asia and the northern half of Africa. It is migratory in the northern part of its range. It spends most of the time on the ground probing for grubs and insects. The clutch of seven to eight eggs is laid in an existing cavity. The eggs are incubated by the female and hatch asynchronously. Some ornithologists treat the African and Madagascar hoopoes as subspecies of the Eurasian hoopoe. Taxonomy The Eurasian hoopoe was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He cited the earlier descriptions by the French naturalist Pierre Belon and by the Swiss naturalist Conrad Gessner, both of which ...

Upupa Africana
The African hoopoe (''Upupa africana'') is a species of hoopoe in the family Upupidae. Previously considered as a subspecies (''Upupa epops africana'') of the Eurasian hoopoe, it is a resident species of southern Africa. Taxonomy The African hoopoe was formally described in 1811 by the German naturalist Johann Matthäus Bechstein under the present binomial name ''Upupa africana''. It is now sometimes treated as a subspecies of the Eurasian hoopoe (''Upupa epops''). The species is monotypic: no subspecies are recognised. Description The African hoopoe has the average size of , with a wingspan between . The weight is between 38 and 67 g when fully grown. This is about the size of the average American robin. African hoopoes have a crest which is chestnut coloured with black on the tips. It is raised when the bird has been startled or disturbed, especially when eating. No eyerings or eye-stripes are present, but the bill is long, dark and narrow and slightly down curved. The ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bucerotiformes
Bucerotiformes is an order of birds that contains the hornbills, ground hornbills, hoopoes and wood hoopoes. These birds were previously classified as members of Coraciiformes. The clade is distributed in Africa, Asia, Europe and Melanesia. Systematics Recent genetic data show that ground hornbills and ''Bycanistes'' form a clade outside the rest of the hornbill lineage. They are thought to represent an early African lineage, while the rest of Bucerotiformes evolved in Asia. The hoopoe subspecies Saint Helena hoopoe and the Madagascar subspecies are sometimes elevated to a full species. The two wood hoopoe genera, ''Phoeniculus'' and ''Rhinopomastus'', appear to have diverged about 10 million years ago, so some systematists treat them as separate subfamilies or even separate families. Extinct Messelirrisoridae and Laurillardiidae families were both considered to be stem groups of a previously categorized Upupiformes order prior to it being subcategorized into Bucerotifo ...

Upupa Marginata
The Madagascar hoopoe (''Upupa marginata'') is a species of hoopoe in the family Upupidae. It was previously considered a subspecies (''Upupa epops marginata'') of the hoopoe, but was split due to its vocalisations and small differences in plumage. Some taxonomists still consider all three species conspecific. Some authorities also keep the African and Eurasian hoopoe together, but split the Madagascar hoopoe. It is endemic to Madagascar, where its natural habitat is subtropical or tropical dry forest. It is a common bird and the International Union for Conservation of Nature considers its conservation status to be of least concern. Description The adult Madagascar hoopoe is about long and weighs . It has a long, decurved bill, and cinnamon-coloured plumage, the wings being boldly barred in black and white. The tail is black and a long, cinnamon crest with black-tipped feathers can be raised when the bird is alarmed. The wings are broad and rounded; the characteristic flight co ...

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 swim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Hoopoe
The wood hoopoes or scimitarbills are a small African family, Phoeniculidae, of near passerine birds. They live south of the Sahara Desert and are not migratory. While the family is now restricted to Sub-Saharan Africa, fossil evidence shows that it once had a larger distribution. Fossils attributed to this family have been found in Miocene rocks in Germany. The wood hoopoes are related to the kingfishers, the rollers, and the hoopoe, forming a clade with this last according to Hackett ''et al.'' (2008). A close relationship between the hoopoe and the wood hoopoes is also supported by the shared and unique nature of their stapes. The wood hoopoes most resemble the true hoopoes with their long down-curved bills and short rounded wings. According to genetic studies, the two genera, ''Phoeniculus'' and ''Rhinopomastus'', appear to have diverged about ten million years ago, so some systematists treat them as separate subfamilies or even separate families.

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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Stapes
The ''stapes'' or stirrup is a bone in the middle ear of humans and other animals which is involved in the conduction of sound vibrations to the inner ear. This bone is connected to the oval window by its annular ligament, which allows the footplate to transmit sound energy through the oval window into the inner ear. The ''stapes'' is the smallest and lightest bone in the human body, and is so-called because of its resemblance to a stirrup ( la, Stapes). Structure The ''stapes'' is the third bone of the three ossicles in the middle ear and the smallest in the human body. It measures roughly , greater along the head-base span. It rests on the oval window, to which it is connected by an annular ligament and articulates with the '' incus'', or anvil through the incudostapedial joint. They are connected by anterior and posterior limbs ( la, crura). Development The ''stapes'' develops from the second pharyngeal arch during the sixth to eighth week of embryological life. T ...

Onomatopoetic
Onomatopoeia is the process of creating a word that phonetically imitates, resembles, or suggests the sound that it describes. Such a word itself is also called an onomatopoeia. Common onomatopoeias include animal noises such as ''oink'', ''meow'' (or ''miaow''), ''roar'', and ''chirp''. Onomatopoeia can differ between languages: it conforms to some extent to the broader linguistic system; hence the sound of a clock may be expressed as ''tick tock'' in English, in Spanish and Italian (shown in the picture), in Mandarin, in Japanese, or in Hindi. The English term comes from the Ancient Greek compound ''onomatopoeia'', 'name-making', composed of ''onomato''- 'name' and -''poeia'' 'making'. Thus, words that imitate sounds can be said to be onomatopoeic or onomatopoetic. Uses In the case of a frog croaking, the spelling may vary because different frog species around the world make different sounds: Ancient Greek (only in Aristophanes' comic play ''The Frogs'') probab ...
