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, h ...

Great Thrush
The great thrush (''Turdus fuscater'') is a species of bird in the family Turdidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. It is considered as the largest thrush in South America. The great thrush's size distinguishes it from the several other uniform slaty-colored thrushes in its range. It inhabits subtropical or tropical moist montane forests and high-altitude shrubland, but can also make use of degraded forest and urban areas. Subspecies Seven subspecies are recognized: * ''T. f. fuscater'' (d´Orbigny, Lafresnaye, 1837). The nominate subspecies can be found in west Bolivia. * ''T. f. cacozelus'' (Bangs, 1898). It can be found in the Santa Marta mountain range in Colombia. * ''T. f. clarus'' (Phelps, Phelps, 1953). Inhabits the frontier between Venezuela and Colombia, in the Sierra del Perijá. * ''T. f. quindio'' (Chapman, 1925). This subspecies is found in south Colombia and the north of Ecuador. * ''T. f. gigas'' (Fraser, 1841). It is native to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Whistling Thrush
The blue whistling thrush (''Myophonus caeruleus'') is a whistling thrush that is found in the mountains of Central Asia, South Asia, China and Southeast Asia. It is known for its loud human-like whistling song at dawn and dusk. The widely distributed populations show variations in size and plumage with several of them considered as subspecies. Like others in the genus, they feed on the ground, often along streams and in damp places foraging for snails, crabs, fruits and insects. Description This whistling thrush is dark violet blue with shiny spangling on the tips of the body feathers other than on the lores, abdomen and under the tail. The wing coverts are a slightly different shade of blue and the median coverts have white spots at their tips. The bill is yellow and stands in contrast. The inner webs of the flight and tail feathers is black. The sexes are similar in plumage. It measures in length. Weight across the subspecies can range from . For comparison, the blue whistl ...

Groundscraper Thrush
The groundscraper thrush (''Turdus litsitsirupa'') is a passerine bird of southern and eastern Africa belonging to the thrush (bird), thrush family, Turdidae. It was previously considered the Monotypic taxon, only member of the genus ''Psophocichla'', but phylogenetic analysis supports it belonging in the genus ''True thrush, Turdus'', of which it is the most Basal (phylogenetics), basal species. It is long with an erect posture, short tail, heavy beak, bill and fairly long legs. The upperparts are plain grey-brown with a chestnut wing-panel. The underparts are white with black spots and the face is white with bold black markings. The underwing has a black and white pattern which is visible during the undulating flight. The bird has a slow whistled bird song, song and a clicking call. There are four subspecies: ''T. l. litsitsirupa'' is the most southerly form, occurring from Namibia, Botswana, Zimbabwe and Mozambique south to northern and eastern parts of South Africa.

Myadestinae
Myadestinae (the turdid solitaires) are a subfamily of passerine birds in the family 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 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 ''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 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 (m .... ...

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.

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 tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluebird
The bluebirds are a North American group of medium-sized, mostly insectivorous or omnivorous birds in the order of Passerines in the genus ''Sialia'' of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. Bluebirds have blue, or blue and rose beige, plumage. Female birds are less brightly colored than males, although color patterns are similar and there is no noticeable difference in size. Taxonomy and species The genus ''Sialia'' was introduced by the English naturalist William John Swainson in 1827 with the eastern bluebird (''Sialia sialis'') as the type species. A molecular phylogenetic study using mitochondrial sequences published in 2005 found that ''Sialia'', '' Myadestes'' (solitaires) and '' Neocossyphus'' (African ant-thrushes) formed a basal clade in the family Turdidae. Within ''Sialia'' the mountain bluebird was sister to the eastern bluebird. The genus contains three species: Behavior Bluebirds are territorial and ...

Dispersal Vector
A dispersal vector is an agent of biological dispersal that moves a dispersal unit, or organism, away from its birth population to another location or population in which the individual will reproduce. These dispersal units can range from pollen to seeds to fungi to entire organisms. There are two types of dispersal vector, those that are active and those that are passive. Active dispersal involves organisms that are capable of movement under their own energy. In passive dispersal, the organisms have evolved dispersal units, or propagules, that use the kinetic energy of the environment for movement. In plants, some dispersal units have tissue that assists with dispersal and are called diaspores. Some dispersal is self-driven (autochory), such as using gravity (barochory), and does not rely on external vectors. Other types of dispersal are due to external vectors, which can be biotic vectors, such as animals (zoochory), or abiotic vectors, such as the wind (anemochory) or water (hy ...

Abiotic
In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole. They affect a plethora of species, in all forms of environmental conditions, such as marine or land animals. Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms. Component degradation of a substance occurs by chemical or physical processes, e.g. hydrolysi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biotic Component
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. In ...
