Traill's Flycatcher
Traill's flycatcher was a supposed species of tyrant flycatcher in the genus '' Empidonax'', called ''Empidonax traillii''. It was named by John James Audubon John James Audubon (born Jean-Jacques Rabin; April 26, 1785 – January 27, 1851) was an American self-trained artist, naturalist, and ornithologist. His combined interests in art and ornithology turned into a plan to make a complete pictoria ... after his good British friend Thomas Stewart Traill. It is now considered to be two distinct but closely related species, which are outwardly very similar but prefer differing habitats and replace each other geographically without significant hybridization: *Alder flycatcher, '' Empidonax alnorum'' *Willow flycatcher, '' Empidonax traillii'' proper References {{Animal common name Empidonax Tyrannidae Birds by common name ...

Empidonax Traillii
The willow flycatcher (''Empidonax traillii'') is a small insect-eating, neotropical migrant bird of the tyrant flycatcher family. There are four subspecies of the willow flycatcher currently recognized, all of which breed in North America (including three subspecies that breed in California). ''Empidonax'' flycatchers are almost impossible to tell apart in the field so biologists use their songs to distinguish between them. The binomial commemorates the Scottish zoologist Thomas Stewart Traill. Description and ecology Adults have brown-olive upperparts, darker on the wings and tail, with whitish underparts; they have an indistinct white eye ring, white wing bars and a small bill. The breast is washed with olive-gray. The upper part of the bill is gray; the lower part is orangish. At one time, this bird and the alder flycatcher (''Empidonax alnorum'') were considered to be a single species, Traill's flycatcher. The willow and alder flycatchers were considered the same species u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrant Flycatcher
The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America. They are considered the largest family of birds known to exist in the world, with more than 400 species. They are the most diverse avian family in every country in the Americas, except for the United States and Canada. The members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers may superficially resemble the Old World flycatchers, which they are named after but are not closely related to. They are members of suborder Tyranni (suboscines), which do not have the sophisticated vocal capabilities of most other songbirds.del Hoyo, J. Elliott, A. & Christie, D. (editors). (2004) ''Handbook of the Birds of the World. Volume 9: Cotingas to Pipits and Wagtails''. Lynx Edicions. A number of species previously included in this family are now placed in the family Tityridae (''see Systematics''). Sibley and Alquist in their 1990 bird taxonomy had the ...

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 ...

Empidonax
The genus ''Empidonax'' is a group of small insect, insect-eating passerine birds in the tyrant flycatcher family, the Tyrannidae. The genus name ''Empidonax'' is from Ancient Greek ''empis'', "gnat", and ''anax'', "master". Most of these birds are very similar in Feather, plumage: olive on the upper parts with light underparts, eye rings and wing bars. In the nesting season they may be distinguished by range, habitat (ecology), habitat and call; in other situations, particularly on bird migration, migration and in winter, it may not be possible to be sure of specific identification. ''Empidonax'' flycatchers often flick their wings and tails rapidly. Euler's flycatcher, ''Lathrotriccus euleri'' and gray-breasted flycatcher, ''Lathrotriccus griseipectus'' were formerly placed in ''Empidonax'', but differ anatomically and biochemically and are now placed in the genus ''Lathrotriccus''.

John James Audubon
John James Audubon (born Jean-Jacques Rabin; April 26, 1785 – January 27, 1851) was an American self-trained artist, naturalist, and ornithologist. His combined interests in art and ornithology turned into a plan to make a complete pictorial record of all the bird species of North America. He was notable for his extensive studies documenting all types of American birds and for his detailed illustrations, which depicted the birds in their natural habitats. His major work, a color-plate book titled ''The Birds of America'' (1827–1839), is considered one of the finest ornithological works ever completed. Audubon is also known for identifying 25 new species. He is the eponym of the National Audubon Society, and his name adorns a large number of towns, neighborhoods, and streets across the United States. Dozens of scientific names first published by Audubon are still in use by the scientific community. Early life Audubon was born in Les Cayes in the French colony of Saint-Dom ...

Thomas Stewart Traill
Thomas Stewart Traill (29 October 1781 – 30 July 1862) was a British physician, chemist, meteorologist, zoologist and scholar of medical jurisprudence. He was the grandfather of the physicist, meteorologist and geologist Robert Traill Omond FRSE (1858-1914). Early life Traill was born at Kirkwall in Orkney, the son of the Rev Thomas Traill (died 1782), the minister in Kirkwall, and his wife Lucia. His father died the year after he was born. He studied medicine at the University of Edinburgh, gaining his doctorate (MD) in 1802. He was elected a Fellow of the Royal Society of Edinburgh in 1819. His proposers were Robert Jameson, John Murray, Lord Murray, and Thomas Charles Hope. He was Curator of the Society's museum from 1834 to 1856. He practised medicine for 30 years in Liverpool, and was a founder of the Royal Institution of Liverpool, the Liverpool Mechanics' Institution and the Literary and Philosophical Society of Liverpool. He became acquainted with the Arctic exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empidonax Alnorum
The alder flycatcher (''Empidonax alnorum'') is a small insect-eating bird of the tyrant flycatcher family. The genus name ''Empidonax'' is from Ancient Greek ''empis'', "gnat", and ''anax'', "master". The specific ''alnorum'' is Latin and means "of the alders". Description ''E. alnorum'' is one of the larger ''Empidonax'' species, attaining a length of , and a mass of . The wingspan ranges from . Upperparts of ''E. alnorum'' are dull greenish-olive. The crown is a slightly darker olive-green than the back. The throat is white, with a darker breast band. Thin white rings surround the eyes.
