Ring Doves
The Barbary dove, ringed turtle dove, ringneck dove, ring-necked turtle dove, or ring dove (''Streptopelia risoria'') is a domestic member of the dove and pigeon family (Columbidae). Taxonomy and domestication The Barbary dove was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the doves and pigeons in the genus ''Columba'' and coined the binomial name ''Columba risoria''. Linnaeus specified the type locality as India. The specific epithet ''risoria'' is Latin meaning "laughing". The Barbary dove was formerly believed to be a domesticated form of the Eurasian collared dove (''Streptopelia decaocto''), but genetic evidence has shown that it is a domesticated form of the African collared dove (''Streptopelia roseogrisea''). There is a disagreement as to whether ''risoria'' should replace ''roseogrisea'' as the epithet for the African collared dove. In 2008 the International Commission on ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Gill (ornithologist)
Frank Bennington Gill (born October 2, 1941 in New York City) is an American ornithologist with worldwide research interests and birding experience. He is perhaps best known as the author of the textbook ''Ornithology'' (4th edition, 2019), the leading textbook in the field. Gill was raised in Teaneck, New Jersey. He reported that he became interested in birds at the age of seven, when his grandfather, Frank Rockingham Downing, showed him a song sparrow at a birdbath. This was the first time he had seen a bird through binoculars, "and I was hooked." After Gill received his PhD in zoology from the University of Michigan in 1969 (where he had also completed his undergraduate degree), he joined the ornithology department at the Academy of Natural Sciences in Philadelphia. From 1969 to 1995, Gill was a full-time staff member of the academy, where he held various positions throughout his tenure, including that of chairman for the Department of Ornithology and vice president fo ...

Rattlesnake
Rattlesnakes are venomous snakes that form the genus, genera ''Crotalus'' and ''Sistrurus'' of the subfamily Crotalinae (the pit vipers). All rattlesnakes are vipers. Rattlesnakes are predators that live in a wide array of habitats, hunting small animals such as birds and rodents. Rattlesnakes receive their name from the #Rattle, rattle located at the end of their tails, which makes a loud rattling noise when tail vibration, vibrated that deters predators. Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened; if treated promptly, the bites are seldom fatal. The 36 known List of rattlesnake species and subspecies, species of rattlesnakes have between 65 and 70 subspecies, all native to the Americas, ranging from central Argentina to southern Canada. The largest rattlesnake, the Eastern diamondback rattlesnake, eastern diamondback, can measure up to in length. Rattlesnakes are preyed upon by hawks, wease ...

Vertebrate
Vertebrates () are animals with a vertebral column (backbone or spine), and a cranium, or skull. The vertebral column surrounds and protects the spinal cord, while the cranium protects the brain. The vertebrates make up the subphylum Vertebrata with some 65,000 species, by far the largest ranked grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata. The jawed fish include both the Chondrichthyes, cartilaginous fish and the Osteichthyes, bony fish. Bony fish include the Sarcopterygii, lobe-finned fish, which gave rise to the tetrapods, the animals with four limbs. Despite their success, vertebrates still only make up less than five percent of all described animal species. The first vertebrates appeared in the Cambrian explosion some 518 million years ago. Jawed vertebrates evolved in the Ordovician, followed by bony fishes in the Devonian. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lung
The lungs are the primary Organ (biology), organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the Vertebral column, backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the atmosphere and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their musculoskeletal systems to support and foster breathing. In early tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the primary muscle that drives breathing is the Thoracic diaphragm, diaphragm. The lungs also provide airflow that makes Animal communication#Auditory, vocalisation including speech possible. Humans have two lungs, a ri ...

Muscle
Muscle is a soft tissue, one of the four basic types of animal tissue. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Muscle tissue gives skeletal muscles the ability to muscle contraction, contract. Muscle tissue contains special Muscle contraction, contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins, present are two regulatory proteins, troponin and tropomyosin. Muscle is formed during embryonic development, in a process known as myogenesis. Skeletal muscle tissue is striated consisting of elongated, multinucleate muscle cells called muscle fibers, and is responsible for movements of the body. Other tissues in skeletal muscle include tendons and perimysium. Smooth and cardiac muscle contract involuntarily, without conscious intervention. These muscle types may be activated both through the interaction of the central nervous system as well as by innervation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homing Pigeon
The homing pigeon is a variety of domestic pigeon (''Columba livia domestica''), selectively bred for its ability to find its way home over extremely long distances. Because of this skill, homing pigeons were used to carry messages, a practice referred to as " pigeon post". Until the introduction of telephones, they were used commercially to deliver communication; when used during wars, they were called "war pigeons". The homing pigeon is also called a mail pigeon or messenger, and colloquially a homer. Perhaps most commonly, the homing pigeon is called a carrier pigeon; this nomenclature can be confusing, though, since it is distinct from the English carrier, an ancient breed of fancy pigeon. Modern-day homing pigeons do have English carrier blood in them because they are in part descendants of the old-style carriers. The domestic pigeon is derived from the wild rock dove (''Columba livia'' sspp.); the rock dove has an innate homing ability, meaning that it will generally re ...

Release Dove
A release dove is usually a small white Domestic pigeon, domestic rock dove used for events such as public ceremonies, weddings and funerals. They typically have a symbolic meaning for the event. Subspecies and types Typically one or more white doves are released. Sometimes doves are called pigeons, there is no distinction. Usually Domestic pigeon, domestic rock doves (''Domestic pigeon, Columba livia domestica'') bred for small size and white coloration are released due to their homing ability. Barbary doves (''Streptopelia risoria''), also known as ringneck doves, carry a mutation that makes them completely white. These white Barbary doves are most commonly used in stage magic acts. White Barbary doves are sometimes released in large public ceremonies as a peace symbol, and at weddings and funerals. However, releases usually use Homing pigeon, homing pigeons, as Barbary doves lack the homing instinct and will die if released into the wild. Albinism or other Genetics, ge ...
