Antbirds
The antbirds are a large passerine bird family (biology), family, Thamnophilidae, found across subtropical and tropical Central and South America, from Mexico to Argentina. There are List of antbirds, more than 230 species, known variously as antshrikes, antwrens, antvireos, fire-eyes, bare-eyes and bushbirds. They are related to the antthrushes and antpittas (family Formicariidae), the tapaculos, the gnateaters and the Ovenbird (family), ovenbirds. Despite some species' common names, this family is not closely related to the wrens, vireos or shrikes. Antbirds are generally small birds with rounded wings and strong legs. They have mostly sombre grey, white, brown and rufous plumage, which is sexual dimorphism, sexually dimorphic in pattern and colouring. Some species communicate warnings to rivals by exposing white feather patches on their backs or shoulders. Most have heavy beak, bills, which in many species are hooked at the tip. Most species live in forests, although a few ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicolored Antbird
The bicolored antbird (''Gymnopithys bicolor'') is a species of bird in the family Thamnophilidae. It is found in Honduras south to Panama, western Colombia and Ecuador. Its natural habitat is subtropical or tropical moist lowland forest. It is dark brown with a white belly and grey and black facial markings. Taxonomy The bicolored antbird was species description, described by the American amateur ornithologist George Newbold Lawrence in 1863 and given the binomial name ''Pithys bicolor''. There are five recognised subspecies: * ''G. b. olivascens'' (Robert Ridgway, Ridgway, 1891) – Honduras to west Panama * ''G. b. bicolor'' (Lawrence, 1863) – east Panama and northwest Colombia * ''G. b. daguae'' Carl Eduard Hellmayr, Hellmayr, 1906 – west Colombia * ''G. b. aequatorialis'' (Hellmayr, 1902) – southwest Colombia and west Ecuador * ''G. b. ruficeps'' Osbert Salvin, Salvin & Frederick DuCane Godman, Godman, 1892 – central Colombia The bicolored antbird was formerly cons ...

Formicariidae
Formicariidae is a family of smallish passerine birds of subtropical and tropical Central and South America known as formicariids. They are between in length, and are related to the antbirds, Thamnophilidae, and gnateaters, Conopophagidae. This family contains probably (see below) some 12 species in two fairly small genera. These are forest birds that tend to feed on insects at or near the ground. Most are drab in appearance with shades of (rusty) brown, black, and white being their dominant tones. Compared to other birds that specialize in following ants, this family is the most tied to the ground. The long, powerful legs (which lend the birds a distinctive upright posture) and an essentially vestigial tail aid this lifestyle. They lay two or three eggs in a nest in a tree, both sexes incubating. Systematics The antthrushes in the genera ''Formicarius'' and ''Chamaeza'' are similar in appearance to small rails. Their sexes are alike in plumage, and they walk like starlings. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Army Ant
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera ''Cheliomyrmex'', ''Neivamyrmex'', ''Nomamyrmex'', ''Labidus'', and ''Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is ''Eciton burchellii''; its common name "army ant" is considered to b ...

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] |
Ovenbird (family)
Ovenbirds or furnariids are a large family of small suboscine passerine birds found from Mexico and Central to southern South America. They form the family Furnariidae. This is a large family containing around 315 species and 70 genera. The ovenbird (''Seiurus aurocapilla''), which breeds in North America, is not a furnariid – rather it is a distantly related bird of the wood warbler family, Parulidae. The ovenbirds are a diverse group of insectivores which get their name from the elaborate, vaguely "oven-like" clay nests built by the horneros, although most other ovenbirds build stick nests or nest in tunnels or clefts in rock.Remsen, J. V., Jr. 2003. Family Furnariidae (ovenbirds). Pages 162–357 in J. del Hoyo, A. Elliott and D. A. Christie eds. Handbook of the birds of the world, Vol. 8, broadbills to tapaculos. Lynx Edicions, Barcelona. The Spanish word for "oven" ''(horno)'' gives the horneros their name. Furnariid nests are always constructed with a cover, and up to six ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped'), which includes more than half of all bird species. Sometimes known as perching birds, passerines are distinguished from other orders of birds by the arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al. (2015"A Paleogene origin for crown passerines and the diversification of the Oscines in the New World" ''Molecular Phylogenetics and Evolution'', 88:1–15. Passerines are divided into three clades: Acanthisitti (New Zealand wrens), Tyranni (suboscines), and Passeri (oscines or songbirds). The passeri ...

Shrike
Shrikes () are passerine birds of the family Laniidae. The family is composed of 34 species in four genera. The family name, and that of the largest genus, ''Lanius'', is derived from the Latin word for "butcher", and some shrikes are also known as butcherbirds because of their feeding habits. The common English name shrike is from Old English , alluding to the shrike's shriek-like call. Distribution, migration, and habitat Most shrike species have a Eurasian and African distribution, with just two breeding in North America (the loggerhead and northern shrikes). No members of this family occur in South America or Australia, although one species reaches New Guinea. The shrikes vary in the extent of their ranges, with some species, such as the great grey shrike, ranging across the Northern Hemisphere; to the Newton's fiscal, which is restricted to the island of São Tomé. They inhabit open habitats, especially steppe and savannah. A few species of shrikes are forest dwell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapaculo
The tapaculos or tapacolos are a family, Rhinocryptidae, of small suboscine passerine birds, found mainly in South America and with the highest diversity in the Andean regions. Three species ( Chocó, Tacarcuna, and the silvery-fronted) are found in southern Central America. Description Tapaculos are small to medium-sized birds, with a total length ranging from 10–24 cm (4–9½ in). These are terrestrial species that fly only poorly on their short wings. They have strong legs, well-suited to their habitat of grassland or forest undergrowth. The tail is cocked and pointed towards the head, and the name ''tapaculo'' probably derives from Spanish for loincloth (literally "cover your behind" --because it ought to). Another possible explanation is that it originates from the Chilean name for the white-throated tapaculo, simply ''tapaculo'', which is an onomatopoeic reference to its commonly heard song. While the majority of the family are small blackish or bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Sternum
The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word "sternum" originates from the Ancient Greek στέρνον (stérnon), meaning "chest". Structure The sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. Its top is also connected to the sternocleidomastoid muscle. The sternum consists of three main parts, listed from the top: * Manubrium * Body (gladiolus) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
