Belted Flycatcher
The belted flycatcher (''Xenotriccus callizonus'') is a species of bird in the family Tyrannidae. It is found in southern Mexico, Guatemala and El Salvador. It is threatened by habitat loss. Description This bird is relatively dull in appearance, though it does sport a flashy crest. The upperparts are a light brown, the underparts a dull yellow. Other features include a pale eye-ring and cocoa wing-bars and chest band, the latter giving it its name. Similar species include the pileated flycatcher and tufted flycatcher. The bird is usually relatively reclusive, opting to remain concealed in thickets, leaving to hawk or glean insects. It is usually relatively solitary and most likely socially monogamous. Ecology Its natural habitat is subtropical or tropical dry scrub forest, especially that dominated by oaks and pines A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family (biology), family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoidea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonathan Dwight
Jonathan Dwight V (1858–1929) was an American ornithologist. Life Jonathan Dwight was born December 8, 1858 in New York City. His father was civil engineer Jonathan Dwight (1831–1910), grandfather Jonathan Dwight (1799–1856), great grandfather Jonathan Dwight (1772–1840), and great-great grandfather also named Jonathan Dwight (1743–1831), all part of the large New England Dwight family. His mother was Julia Lawrence Hasbrouck. In 1861 the family moved to Madison, New Jersey. His family had a summer home in Tadoussac, Quebec, and his first paper was published in 1879 on the birds observed there. He graduated from Harvard University in 1880, and joined his father in railroad design. He enlisted in the New York National Guard in 1889. After serving in the ambulance corps, he developed an interest in medicine. In 1893 he entered the Columbia University College of Physicians and Surgeons. He worked for a while in a hospital and private practice, but over time devoted more ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrub Forest
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high and subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1927
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Quercus
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably '' Lithocarpus'' (stone oaks), as well as in those of unrelated species such as ''Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. ...

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] |
Ludlow Griscom
Ludlow Griscom (June 17, 1890 – May 28, 1959) was an American ornithologist known as a pioneer in field ornithology. His emphasis on the identification of free-flying birds by field marks became widely adopted by professionals and amateurs. Many called him "Dean of the Birdwatchers." Early life and family Griscom was born in New York City, the son of Clement Acton Griscom Jr. and Genevieve Sprigg Ludlow. Ludlow's grandfather Clement Acton Griscom Sr. was a prominent merchant and shipping executive. His maternal grandfather, William Ludlow, distinguished himself through military service. Griscom's family traces its ancestry back to Thomas Lloyd, a 17th-century physician in Pennsylvania. The oldest of three children, Ludlow Griscom had a sister, Joyce, who died in childhood, and a brother, Acton. As a boy, Ludlow's interest in birds showed itself as early as 1898. In 1907, he found fellow nature enthusiasts when he joined the Linnaean Society of New York. Griscom recei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tufted Flycatcher
The northern tufted flycatcher or simply tufted flycatcher (''Mitrephanes phaeocercus'') is a small passerine bird in the tyrant flycatcher family. It breeds in highlands from northwestern Mexico to northwestern Ecuador. The olive flycatcher (''Mitrephanes olivaceus'') of Peru and Bolivia is now considered a separate species. It is a common inhabitant of mature mountain forest and tall second growth, especially at edges and clearings with trees. It breeds from 700–3000 m altitude, but is most abundant from 1200–2150 m. The female builds a saucer nest of moss, liverworts and lichens 4–27 m high on a branch or vine, usually concealed among ferns, bromeliads and other epiphytes. The female incubates the two brown-blotched white eggs for 15–16 days to hatching, The northern tufted flycatcher is 12 cm long and weighs 8.5 g. The upperparts are olive-green, including the pointed crest. The tail and wings are blackish, and the latter have two buf ...
