Myadestinae
Myadestinae (the turdid solitaires) are a subfamily of passerine birds in the family Thrush (bird), Turdidae. Members of this group have been noted by ornithologists to be rather unusual in that they lack the typical diagnostic traits seen in the "true" thrushes of the sister subfamily Turdinae. Examples of including the lack Syrinx (bird anatomy), syringeal morphology seen in turdines and the feeding ecology of myadestines being similar to those of Old World flycatchers. A 2005 molecular study from Klicka et al. found support in a basal clade consisting of the genera ''Bluebird, Sialia'', ''Neocossyphus'', ''Stizorhina'', and ''Myadestes'' to be sister to the rest of the thrushes. The divergence between myadestines and turdines occurred 11 million years ago in the Serravallian. References Turdidae, * Thrushes, Bird subfamilies {{Turdidae-stub ...

Thrushes
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists reclassified the former subfamily Saxicolinae, which includes the chats and European robins, as Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family. Characteristics Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas, and often feeding on the ground. The smallest thrush may be the forest rock thrush, at and . However, the shortwings, which have ambiguous alliances with both thrushes and Old World flycatchers, can be even smaller. The lesser shortwing averages . The largest thrush is the Great thrush at and , though the commonly recognized Blue whistling-thrush is an Old world flycatcher. The Amami thrush might, howe ...

Turdinae
Turdinae (the turdine thrushes) are a subfamily of passerine birds in the family Turdidae. They are the sister clade to the subfamily Myadestinae. The divergence between myadestines and turdines occurred 11 million years ago in the Serravallian. Within the turdines they can split into three subgroups: '' Zoothera'' occupying a basal position, the second consisting of forest thrush genera ('' Ixoreus'', '' Ridgwayia'', ''Cichlopsis'', ''Entomodestes'', '' Hylocichla'', and ''Catharus'') and the remaining group closer to ''Turdus'' ('' Chlamydochaera'', ''Cochoa'', ''Geokichla The ''Geokichla'' thrushes are medium-sized mostly insectivorous or omnivorous birds in the thrush family, Turdidae.

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 ...

Old World Flycatcher
The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World (Europe, Africa and Asia), with the exception of several vagrants and two species, Bluethroat (''Luscinia svecica)'' and Northern Wheatear (''Oenanthe oenanthe''), found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family includes 344 species and is divided into 51 genera. Taxonomy The name Muscicapa for the family was introduced by the Scottish naturalist John Fleming in 1822. The word had earlier been used for the genus ''Muscicapa'' by the French zoologist Mathurin Jacques Brisson in 1760. Muscicapa comes from the Latin ''musca'' meaning a fly and '' capere'' to catch. In 1910 the German ornithologist Ernst Hartert found it impossible to define boundaries between the three families Muscicapidae, Sylviidae (Old World warblers) and Turdidae (thrushes). He therefore treat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syrinx (bird Anatomy)
The syrinx (from the Greek word "σύριγξ" for ''pan pipes'') is the vocal organ of birds. Located at the base of a bird's trachea, it produces sounds without the vocal folds of mammals. The sound is produced by vibrations of some or all of the ''membrana tympaniformis'' (the walls of the syrinx) and the ''pessulus'', caused by air flowing through the syrinx. This sets up a self-oscillating system that modulates the airflow creating the sound. The muscles modulate the sound shape by changing the tension of the membranes and the bronchial openings. The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs. Thus, lateralization is possible, with muscles on the left and right branch modulating vibrations independently so that some songbirds can produce more than one sound at a time. Some species of birds, such as New World vultures, lack a syrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serravallian
The Serravallian is, in the geologic timescale, an List of time periods, age or a stage (stratigraphy), stage in the middle Miocene epoch (geology), Epoch/series (stratigraphy), Series, which spans the time between 13.82 annum, Ma and 11.63 Ma (million years ago). The Serravallian follows the Langhian and is followed by the Tortonian. It overlaps with the middle of the Astaracian European Land Mammal Mega Zone, the upper Barstovian and lower Clarendonian North American Land Mammal Ages and the Laventan and lower Mayoan South American Land Mammal Ages. It is also coeval with the Sarmatian and upper Badenian Stages of the Paratethys time scale of Central and eastern Europe. Definition The Serravallian Stage was introduced in stratigraphy by the Italy, Italian geologist Lorenzo Pareto in 1865. It was named after the town of Serravalle Scrivia in northern Italy. The base of the Serravallian is at the first occurrence of fossils of the Plankton#Size groups, nanoplankton species ''Sph ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.
