Thrasher Brothers
Thrashers are a New World group of passerine birds related to mockingbirds and New World catbirds. Like these, they are in the family Mimidae. There are 15 species in one large and 4 monotypic genera. These do not form a clade but are a phenetic assemblage. It is rather likely than not — though by no means robustly supported — that the sage thrasher is a basal lineage among a group also consisting of mockingbirds and ''Toxostoma'' thrashers. The Caribbean thrashers occupy varying positions in an assemblage consisting of them, the tremblers, and the New World catbirds. Here, the white-breasted thrasher appears to be quite basal though it is impossible to place it anywhere with certainty, whereas the pearly-eyed thrasher is probably quite close to the tremblers. (Hunt ''et al.'' 2001, Barber ''et al.'' 2004) Their common name describes the behaviour of these birds when searching for food on the ground: they use their long bills to "thrash" through dirt or dead leaves.

Brown Thrasher
The brown thrasher (''Toxostoma rufum''), sometimes erroneously called the brown thrush or fox-coloured thrush, is a bird in the family Mimidae, which also includes the New World catbirds and mockingbirds. The brown thrasher is abundant throughout the eastern and central United States and southern and central Canada, and it is the only thrasher to live primarily east of the Rockies and central Texas. It is the state bird of Georgia. As a member of the genus ''Toxostoma'', the bird is relatively large-sized among the other thrashers. It has brown upper parts with a white under part with dark streaks. Because of this, it is often confused with the smaller wood thrush (''Hylocichla mustelina''), among other species. The brown thrasher is noted for having over 1000 song types, and the largest song repertoire of birds. However, each note is usually repeated in two or three phrases. The brown thrasher is an omnivore, with its diet ranging from insects to fruits and nuts. The usual ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Long-billed Thrasher
The long-billed thrasher (''Toxostoma longirostre'') is a medium-sized resident songbird of South Texas and eastern Mexico. It bears a strong resemblance to its close relative the brown thrasher in appearance, calls, and various other behaviors; however, the two species do not overlap in range except in the winter when the brown thrasher will temporarily reside in the northern range of the long-billed. The bird is a large sized mimid that is not especially wary, but it will take precautionary measures to prevent itself from being potential prey. Like other thrashers, it is named after its sweeping methods when searching for food, not for thrashing predators, although they are aggressive defenders of their territories. Taxonomy The specific name ''longirostre'' is derived from the Latin words ''longus'' long and ''rostrum'' bill. There are two subspecies of the long-billed thrasher. ''T. longirostre'' ssp. ''longirostre'' was first described in scientific literature by Frédà ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Thrasher In CP (02147)
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn. Etymology The term is from Old English , in origin for any dusky or dark shade of color. The first recorded use of ''brown'' as a color name in English was in 1000. The Common Germanic adjectives ''*brûnoz and *brûnâ'' meant b ...

Sage Thrasher
The sage thrasher (''Oreoscoptes montanus'') is a medium-sized passerine bird from the family Mimidae, which also includes mockingbirds, tremblers, and New World catbirds. It is the only member of the genus ''Oreoscoptes''. This seems less close to the Caribbean thrashers, but rather to the mockingbirds instead (Hunt ''et al.'' 2001, Barber ''et al.'' 2004). Description ''Oreoscoptes montanus'' are pale grey-brown on the upperparts and white with dark streaks on the underparts. They have a slim straight relatively short bill, yellow eyes and a long tail, although not as long as that of other thrashers. Measurements: * Length: 7.9-9.1 in (20-23 cm) * Weight: 1.4-1.8 oz (40-50 g) * Wingspan: 12.6 in (32 cm) Breeding As its name suggests, this bird breeds in western North America, from southern Canada to northern Arizona and New Mexico. Its breeding habitat is in areas with dense stands of sagebrush and rarely in other shrubby areas. The female lays 4 or 5 eggs in ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pearly-eyed Thrasher
The pearly-eyed thrasher (''Margarops fuscatus'') is a bird in the thrasher family Mimidae. It is found on many Caribbean islands, from the Bahamas in the north to the Grenadines in the south, with an isolated subspecies on Bonaire. Description The pearly-eyed thrasher is the largest species in the Mimidae, growing to 28 to 30 cm (11 to 11.8 inches) in length. Taxonomy Its genus, ''Margarops'', is currently considered monotypic; formerly the scaly-breasted thrasher was placed in the same genus. However, ''M. fusctaus'' is now known to be closer to the ''Cinclocerthia'' tremblers. While this is not a migratory bird, considerable gene flow between populations appears to have taken place at least until fairly recently in its evolutionary history. There are four subspecies, two of which can be distinguished genetically: ''M. f. fuscatus'' (the nominate subspecies, which is found between the Greater Antilles and Antigua and Barbuda), and ''M. f. densirostris'' (oc ...

White-breasted Thrasher
The white-breasted thrasher (''Ramphocinclus brachyurus''), also known as goj blan in Creole, is a species of bird in the family Mimidae. Semper and Sclater (1872) describe the white-breasted thrasher as an "inquisitive and noisy bird" that would often "keep up a constant warning chatter, and throw itself about in all sorts of contortions" when being disturbed. It is endemic to Martinique and Saint Lucia, found only on these two islands of the Lesser Antilles. This resident species is easy to find within its range; however, it is classified as endangered by the IUCN Red List of Threatened Species mainly due to its restricted habitat.BirdLife International. 2012. ''Ramphocinclus'' brachyurus. TheIUCN RedList of Threatened Species. International Union for Conservation of Nature. Retrieved 29 September 2015. Description The white-breasted thrasher is in average 23 to 25 cm long, and weight from 48 to 60 g depending on sex and subspecies.Benstead P, Isherwood I, Mahood S, Popl ...

Trembler
Tremblers are a New World group of passerine birds related to mockingbirds and New World catbirds. Like these, they are in the family Mimidae. There are 2-4 species in one genus, ''Cinclocerthia'', which is endemic to the Lesser Antilles: * Grey trembler (Martinique trembler), ''Cinclocerthia (gutturalis) gutturalis'' ** Saint Lucia trembler, ''Cinclocerthia (gutturalis) macrorhyncha'' * (Southern) brown trembler, ''Cinclocerthia (ruficauda) ruficauda'' ** Northern brown trembler, ''Cinclocerthia (ruficauda) tremula'' Among the living birds, they are apparently most closely related to the pearly-eyed thrasher.Hunt ''et al.'' (2001), Barber ''et al.'' (2004) Their common name comes from their peculiar behavior: if excited, they will show a much more exaggerated version of the wing-flicking also seen in other mimids such as the northern mockingbirds. The tremblers do not just flick their wings, but shake their entire bodies in a trembling motion. Footnotes References * Barb ...

Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...
