Lemon-spectacled Tanager
The lemon-spectacled tanager (''Chlorothraupis olivacea'') is a species of bird in the family Cardinalidae. It is found in Colombia, Ecuador, and Panama where its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest. Description The adult lemon-spectacled tanager is about in length. It is very similar in appearance to the olive tanager but the male is a rather darker shade of dull olive-green with the underparts have less yellow on the throat. The female is also similar to the female olive tanager, the underparts being yellowish-olive, and the only clear distinction between the two species is in the yellow eye-ring, possessed by both sexes of this species; the lemon-spectacled tanager also resembles the ochre-breasted tanager, but that bird has a pale eye and the underparts are more ochraceous. The three species do not share common ranges; the lemon-spectacled tanager is native to weste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithologist from Pennsylvania. He worked as curator and Vice President at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the Academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown, Pennsylvania. His great Uncle, John Cassin, was a commodore in the U.S. Navy and served in the War of 1812. He served in the Union Army during the American Civil War and was held prisoner in the infamous Confederate Libby Prison in Richmond, Virginia. Career Cassin moved to Philadelphia in 1834 and became the head of a lith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive Tanager
The olive tanager (''Chlorothraupis carmioli''), also known as Carmiol's tanager, is a species of bird traditionally placed in the family Thraupidae (tanagers), though molecular evidence indicates it should be placed in Cardinalidae (cardinals). This bird's natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest. Taxonomy Some authorities advocate splitting this species into two. Carmiol's tanager (''C. carmioli'', including subspecies ''magnirostris'' and ''lutescens'') is found in Nicaragua, Costa Rica, Panama and far north-western Colombia (near the Panama border). The name commemorates the German scientist Julian Carmiol who worked in Costa Rica. The other species would be the olive tanager (''C. frenata''), which is found locally in the Andes of Colombia, Ecuador, Peru and Bolivia. Description The adult olive tanager is about long and is an evenly coloured, robust bird. The upper parts are a dull olive green, and the underparts ...

Birds Described In 1860
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Chlorothraupis
''Chlorothraupis'' is a genus of bird in the family Cardinalidae. It was long considered to be a member of the tanager The tanagers (singular ) comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropica ... family (Thraupidae), as their common names suggest, but this is false. They are close relatives of the genus '' Habia'', the "ant-tanagers".

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochre-breasted Tanager
The ochre-breasted tanager (''Chlorothraupis stolzmanni'') is a species of bird in the family Cardinalidae. It is found in Colombia and Ecuador where its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. As a fairly common species with a stable population, the International Union for Conservation of Nature has rated this bird as being of "least concern". Description The ochre-breasted tanager grows to a length of about . The sexes are similar in appearance, the upper parts being drab olive-green. Birds in Colombia show a slight grey shading on the head. The iris of the eye is pale bluish-grey. The underparts are ochraceous buff, with some olive shading on the flanks and breast, the throat being the palest region. It is similar in appearance to the lemon-spectacled tanager and the olive tanager but the three species do not share common ranges; the lemon-spectacled tanager is native to western Colombia and northwes ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtropical Or Tropical Moist Lowland Forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...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] |
