Cozumel Thrasher
The Cozumel thrasher (''Toxostoma guttatum'') is a bird from the mockingbird family ( Mimidae), which is endemic to the island of Cozumel off the Yucatán Peninsula, Mexico. It is believed to be the most critically endangered species of bird in Mexico – if it indeed still exists, which is probable but not certain.ENS (2004) This bird is closely related to the long-billed and brown thrashers. It has been generally described as shy, but there have been descriptions to the contrary. It was once abundant throughout Cozumel before two hurricanes greatly affected its numbers. Invasive species are also thought to have impacted the population of the thrasher. Taxonomy The Cozumel thrasher was first described as ''Harporhynchus guttatus'' by Robert Ridgway in 1885. It has been described as a subspecies to its relative the long-billed thrasher (''Toxostoma longirostre''), but was considered a separate species when it was determined in a 1998 study that it differed genetically more tha ...

Robert Ridgway
Robert Ridgway (July 2, 1850 – March 25, 1929) was an American ornithologist specializing in systematics. He was appointed in 1880 by Spencer Fullerton Baird, secretary of the Smithsonian Institution, to be the first full-time curator of birds at the United States National Museum, a title he held until his death. In 1883, he helped found the American Ornithologists' Union, where he served as officer and journal editor. Ridgway was an outstanding descriptive taxonomist, capping his life work with ''The Birds of North and Middle America'' (eight volumes, 1901–1919). In his lifetime, he was unmatched in the number of North American bird species that he species description, described for science. As technical illustrator, Ridgway used his own paintings and outline drawings to complement his writing. He also published two books that systematized color names for describing birds, ''A Nomenclature of Colors for Naturalists'' (1886) and ''Color Standards and Color Nomenclature'' ...

Lore (anatomy)
The lore (adj. loreal) is the region between the eyes and nostrils of birds, reptiles, and amphibians. Ornithology In ornithology, the lore is the region between the eye and bill on the side of a bird's head. This region is sometimes featherless, and the skin may be tinted, as in many species of the cormorant family. This area, which is directly in front of the eye, features a "loral stripe" in many bird species including the red-capped plover. Herpetology In amphibians and reptiles, lore pertains to the regions immediately adjacent to the eyes and between the eyes and nostrils. These are analogous to the lore on birds which corresponds to the region between the eye and the beak. In snakes and reptiles, a loreal scale also refers to the scales which lie between the eye and the nostril. In crotaline snakes (pit vipers), loreal pits are present on either side of the head.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing ...

Hurricane Emily (2005)
Hurricane Emily was the first July Atlantic hurricane to reach List of Category 5 Atlantic hurricanes, Category 5 status on the Saffir-Simpson scale. It remained the only to have done so until Hurricane Beryl, Beryl of 2024 Atlantic hurricane season, 2024. The fifth named storm, third hurricane, and second major hurricane of the record-breaking 2005 Atlantic hurricane season, Emily formed on 11 July from a tropical wave east of the Lesser Antilles. Three days later, it made landfall (meteorology), landfall on Grenada as a minimal hurricane, just ten months after Hurricane Ivan devastated the region. Emily attained maximum sustained winds of 260 km/h (160 mph) on 16 July while passing southwest of Jamaica, which at the time made it the strongest Atlantic hurricane before the month of August. Slight weakening occurred before Emily made landfall along Mexico's Yucatán Peninsula on 18 July as a Category 4 hurricane. Quickly crossing the peninsula, Emily ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Hurricane Roxanne
Hurricane Roxanne was a rare and erratic tropical cyclone that caused extensive flooding in Mexico due to its unusual movement. The seventeenth storm, tenth hurricane, and the fifth and final major hurricane of the very active 1995 Atlantic hurricane season, Roxanne developed in the southwestern Caribbean Sea from an area of low pressure on October 7. The depression curved northward, causing it to avoid landfall in Central America. By October 9, the depression intensified enough to be upgraded to Tropical Storm Roxanne. On the following day, Roxanne turned west-northward, where it promptly intensified into a hurricane. As Roxanne headed generally westward, it began to rapidly deepen and reached Category 3 intensity less than 24 hours after becoming a hurricane. Shortly thereafter, Roxanne made landfall near Cozumel, Mexico at its peak intensity, which caused severe damage. Roxanne rapidly weakened while traversing the Yucatan Peninsula, and when it emerged into the Bay of Campeche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Gilbert
Hurricane Gilbert was the second most intense tropical cyclone on record in the Atlantic basin in terms of barometric pressure, only behind Hurricane Wilma in 2005. An extremely powerful tropical cyclone that formed during the 1988 Atlantic hurricane season, Gilbert peaked as a Category 5 hurricane that brought widespread destruction to the Caribbean and the Gulf of Mexico, and is tied with 1969's Hurricane Camille as the second-most intense tropical cyclone to make landfall in the Atlantic Ocean. Gilbert was also one of the largest tropical cyclones ever observed in the Atlantic basin. At one point, its tropical storm-force winds measured in diameter. In addition, Gilbert was the most intense tropical cyclone in recorded history to strike Mexico. The seventh List of named tropical cyclones, named storm, third hurricane and first major hurricane of the 1988 Atlantic hurricane season, Gilbert developed from a tropical wave on September 8 while located east of Barbados.

James Bond (ornithologist)
James Bond (January 4, 1900 – February 14, 1989) was an American ornithologist and expert on the birds of the Caribbean, having written the definitive book on the subject: '' Birds of the West Indies'', first published in 1936. He served as a curator of the Academy of Natural Sciences of Philadelphia. His name was appropriated by writer Ian Fleming for his fictional British spy of the same name; the real Bond enjoyed knowing his name was being used this way, and references to him permeate the resulting media franchise. Life and career Bond was born on January 4, 1900, in Philadelphia, Pennsylvania, the son of Margaret Reeves ( Tyson) and Francis Edward Bond. His interest in natural history was spurred by an expedition his father undertook in 1911 to the Orinoco Delta. Bond was educated at the Delancey School followed by St. Paul's School in Concord, New Hampshire, but after the death of his mother he moved with his father to the United Kingdom in 1914. There, he studied at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raymond A
Raymond is a male given name of Germanic origin. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' ( Gothic) and ''regin'' ( Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded ...

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 Griscom, 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 (lieutenant governor), 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 joine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Thrush
The wood thrush (''Hylocichla mustelina'') is a North American passerine bird in the family Turdidae and is the only species placed in the genus ''Hylocichla''. It is closely related to other thrushes such as the American robin and is widely distributed across North America, wintering in Central America and southern Mexico. The wood thrush is the official bird of the District of Columbia. The wood thrush is a medium-sized Thrush (bird), thrush, with brown upper parts with mottled brown and white underparts. The male and female are similar in appearance. The Bird call, song of the male is often cited as being the most beautiful in North America. The wood thrush is an omnivore, and feeds preferentially on soil invertebrates and larvae, but will also eat fruits. In the summer, it feeds on insects continuously in order to meet daily metabolic needs. It is solitary, but sometimes forms mixed-species flocks. The wood thrush defends a Territory (animal), territory that ranges in size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
