Colombian Mountain Grackle
The Colombian mountain grackle (''Macroagelaius subalaris''), is a species of bird in the family Icteridae. Distribution and habitat It is endemic to Colombia where its natural habitat is subtropical or tropical moist montane forests. Conservation It is threatened by habitat loss and declining in numbers. It was uplisted from Near Threatened to Critically Endangered status in 2000, due to fears of a collapse of the presumably tiny population. As the species, while still severely declining, has turned out to be more widespread than believed, it was downlisted to Endangered in the 2007 IUCN Red List The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biol ....See BirdLife International (2007a,b).

Golden-tufted Mountain Grackle
The golden-tufted mountain grackle (''Macroagelaius imthurni''), also known as the golden-tufted grackle, is a species of bird in the family Icteridae. It is found in Brazil, Guyana, and Venezuela where its natural habitat is subtropical or tropical moist 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 crucia ...s.

Icteridae
Icterids () or New World blackbirds make up a family, the Icteridae (), of small to medium-sized, often colorful, New World passerine birds. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the Ancient Greek ''ikteros'' via the Latin ''ictericus''. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques. Despite the similar names, the first groups are only distantly related to the Old World common blackbird (a thrush) or the Old World orioles. The Icteridae are not to be confused with the Icteriidae, a family created in 2017 and consisting of one species — the yellow-breasted chat (''Icteria virens''). Characteristics Most icterid species live in the tropics, although ... [...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.

Bird
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 swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
