Northern House Wren
The northern house wren (''Troglodytes aedon'') is a very small passerine in the wren family Troglodytidae. It found in southern Canada, the USA and Mexico. It occurs in most suburban areas in its range. It formerly included many subspecies resident in South America and in the Caribbean that are now considered as separate species. The name ''troglodytes'' means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. Taxonomy The northern house wren was formally described in 1809 by the French ornithologist Louis Pierre Vieillot under the current binomial name ''Troglodytes aedon''. The specific epithet is from the Ancient Greek ''aēdōn'' meaning "nightingale". The type locality was designated as New York City by Harry Oberholser in 1934. An earlier specific name, ''domestica'' in the combination ''Sylvia domestica'', was introduced in 1808 by the American ornithologist Alexander Wilson. This was rarely ...

Bandelier National Monument
Bandelier National Monument is a United States National Monument near Los Alamos in Sandoval and Los Alamos counties, New Mexico. The monument preserves the homes and territory of the Ancestral Puebloans of a later era in the Southwest. Most of the pueblo structures date to two eras, dating between 1150 and 1600 AD. The monument is of the Pajarito Plateau, on the slopes of the Jemez volcanic field in the Jemez Mountains. Over 70% of the monument is wilderness, with over one mile of elevation change, from about along the Rio Grande to over at the peak of Cerro Grande on the rim of the Valles Caldera, providing for a wide range of life zones and wildlife habitats. of road and more than of hiking trails are built. The monument protects Ancestral Pueblo archeological sites, a diverse and scenic landscape, and the country's largest National Park Service Civilian Conservation Corps National Landmark District.

William Brewster (ornithologist)
William Brewster (July 5, 1851 – July 11, 1919) was an American ornithologist. He co-founded the American Ornithologists' Union (AOU) and was an early naturalist and conservationist. Early life and education Childhood William Brewster was born on July 5, 1851, in South Reading (now Wakefield), Massachusetts, the youngest of four children born to John Brewster, a successful Boston banker, and Rebecca Parker (Noyes). The couple settled in Cambridge, Massachusetts in 1845. Brewster's sister and older brothers died in early childhood, inspiring Longfellow, a close neighbor, to write the poem ''The Open Window''. Brewster attended Cambridge public schools, Washington Grammar School and Cambridge High School, taking a preparatory course to enter Harvard. He suffered eyesight problems as a youth and into adulthood. He was often unable to read or study, sometimes for extended periods. During his last year of high school, he was unable to read so his mother read his lessons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Chord (biology)
Wing chord is an anatomical measurement of a bird's wing. The measurement is taken with the wing bent at a 90-degree angle, from the most prominent point of the wrist joint to the most prominent point of the longest primary feather. It is often taken as a standard measurement of the proportions of a bird and used to differentiate between species and subspecies. See also * Bird measurement Bird measurement or bird biometrics are approaches to quantify the size of birds in scientific studies. The measurements of the lengths of specific parts and the weights of birds varies between species, populations within species, between the sex ... References {{Bird-stub Bird anatomy ...

Cobb's Wren
Cobb's wren (''Troglodytes cobbi'') is a fairly small (12-13.5 cm) wren which is endemic to the Falkland Islands. It was formerly classified as a subspecies of the house wren (''Troglodytes aedon'') but is now commonly considered to be a separate species due to differences in plumage, voice, ecology and morphology. The scientific and common names commemorate Arthur Cobb, an author from the Falkland Islands. Description The plumage is brown, greyer on the head and breast and more rufous on the tail. There are dark bars on the flight feathers and tail. The bill is long, blackish and slightly curved. The main confusion species is the sedge wren which is smaller with a shorter bill, buff eyestripe and dark streaks on the back and head. Cobb's wrens have a number of buzzing calls and their song is a series of jumbled trills and whistles. The song can be heard from August to February and varies between individuals with different males having different song patterns. Behaviour Th ...

Grenada Wren
The Grenada wren (''Troglodytes grenadensis'') is a very small passerine bird in the wren family Troglodytidae that is found on the Caribbean island of Grenada. The name ''troglodytes'' means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the house wren, now renamed the northern house wren (''Troglodytes aedon''). Taxonomy The Grenada wren was formally described in 1878 by the American ornithologist George Newbold Lawrence based on specimens collected by the naturalist Frederick A. Ober on the island of Grenada. Lawrence coined the binomial name ''Thryothorus grenadensis''. The Grenada wren was formerly considered to be a subspecies of the house wren, now renamed the northern house wren (''Troglodytes aedon''). It is now recognised as a separate species based on differences in morphology and genetics. The species is monotypic In biology, a mon ...

Kalinago Wren
The Kalinago wren (''Troglodytes martinicensis'') is a very small passerine bird in the wren family Troglodytidae that is found on the Caribbean island of Dominica. It was formerly also found on the islands of Martinique and Guadeloupe. The name ''troglodytes'' means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the house wren, now renamed the northern house wren (''Troglodytes aedon''). Taxonomy The Kalinago wren was formally described in 1866 by the English zoologist Philip Sclater based on a specimen collected on the island of Martinique. He coined the binomial name ''Thryothorus martinicensis''. The Kalinago wren was formerly considered as conspecific with the house wren (now the northern house wren).

Cozumel Wren
The house wren (''Troglodytes aedon'') is a very small bird of the wren family, Troglodytidae. It occurs from Canada to southernmost South America, and is thus the most widely distributed native bird in the Americas. It occurs in most suburban areas in its range and it is the single most common wren. Its taxonomy is highly complex and some subspecies groups are often considered separate species. The name ''troglodytes'' means "hole dweller", and is a reference to bird's tendency to disappear into crevices when hunting insects or to seek shelter. Taxonomy The house wren was formally described in 1809 by the French ornithologist Louis Jean Pierre Vieillot under the current binomial name ''Troglodytes aedon''. The specific epithet is from the Ancient Greek ''aēdōn'' meaning "nightingale". The type locality was designated as New York City by Harry Oberholser in 1934. There are 32 recognised subspecies. These are sometimes divided into three distinct groups and one or several dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern House Wren
The southern house wren (''Troglodytes musculus'') is a very small passerine bird in the wren family Troglodytidae. It is found from southern Mexico to southern Chile and southern Argentina. The name ''troglodytes'' means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the northern house wren (''Troglodytes aedon''). Taxonomy The southern house wren was formally described in 1823 by the German naturalist Johann Andreas Naumann under the binomial name ''Troglodytes musculus''. He specified the type locality as the state of Bahia in eastern Brazil. The specific epithet is Latin meaning "little mouse". The southern house wren was formerly considered to be part of the house wren complex that also included the northern house wren and six insular forms.

Genetic Divergence
Genetic divergence is the process in which two or more populations of an ancestral species accumulate independent genetic changes (mutations) through time, often leading to reproductive isolation and continued mutation even after the populations have become reproductively isolated for some period of time, as there isn’t genetic exchange anymore. In some cases, subpopulations living in ecologically distinct peripheral environments can exhibit genetic divergence from the remainder of a population, especially where the range of a population is very large (see parapatric speciation). The genetic differences among divergent populations can involve silent mutations (that have no effect on the phenotype) or give rise to significant morphological and/or physiological changes. Genetic divergence will always accompany reproductive isolation, either due to novel adaptations via selection and/or due to genetic drift, and is the principal mechanism underlying speciation. On a molecular gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
