Urohidrosis
Urohidrosis (sometimes misspelled "urohydrosis") is the habit in some birds of defecating onto the scaly portions of the legs as a cooling mechanism, using evaporative cooling of the fluids. Birds' droppings consist of both feces and urine, which are excreted together through the cloaca. Etymology Hidrosis" is the medical term for sweating from Ancient Greek, and the word "urohidrosis" was coined by M. P. Kahl in 1963:...Because of its apparent functional similarity to true sweating, I suggest the term ''urohidrosis'' (Greek: ''ouron'' = urine; ''hidrōs'' = sweat) for this phenomenon.

New World Vulture
Cathartidae, known commonly as New World vultures or condors, are a family (biology), family of birds of prey consisting of seven extant species in five genus, genera. It includes five extant vultures and two extant condors found in the Americas. They are known as "New World" vultures to distinguish them from Old World vultures, with which the Cathartidae does not form a single clade despite the two being similar in appearance and behavior as a result of convergent evolution. Like other vultures, New World vultures are scavengers, having evolved to feed off of the wikt:carcass, carcasses of dead animals without any notable ill effects. Some species of New World vulture have a good sense of smell, whereas Old World vultures find carcasses exclusively by sight. Other adaptations shared by both Old and New World vultures include a bald head (anatomy), head, devoid of feathers which helps prevent rotting matter from accumulating while feeding, and an extremely disease-resistant digest ...

Ciconia Ciconia -Tsavo East National Park, Kenya-8
__NOTOC__ ''Ciconia'' ( ; ) is a genus of birds in the stork family. Six of the seven living species occur in the Old World, but the maguari stork has a South American range. In addition, fossils suggest that ''Ciconia'' storks were somewhat more common in the tropical Americas in prehistoric times. The genus was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the white stork (''Ciconia ciconia'') as the type species. The genus name is the Latin word for "stork", and was originally recorded in the works of Horace and Ovid. The Abdim's stork is the smallest of the family, but other species in the genus are generally medium-sized storks, with long legs and a long thick bill. The members of this genus are more variable in plumage than other stork genera, but all species are black (at least to the wings) and white (at least underparts or neck). Juveniles are a duller, browner version of the adult. Depending on species, breeding can be in solitary pairs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Defecation
Defecation (or defaecation) follows digestion and is the necessary biological process by which organisms eliminate a solid, semisolid, or liquid metabolic waste, waste material known as feces (or faeces) from the digestive tract via the anus or cloaca. The act has a variety of names, ranging from the technical (e.g. bowel movement), to the common (like pooping or crapping), to the obscene (''Shit, shitting''), to the euphemistic ("doing number two", "dropping a deuce" or "taking a dump"), to the juvenile ("going poo-poo" or "making doo-doo"). The topic, usually avoided in polite company, forms the basis of scatological humor. human feces, Humans expel feces with a frequency varying from a few times daily to a few times weekly. Waves of muscle, muscular contraction (known as ''peristalsis'') in the walls of the colon (anatomy), colon move fecal matter through the digestive tract towards the rectum. Flatus may also be expulsed. Undigested food may also be expelled within the fec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evaporative Cooling
An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling exploits the fact that water will absorb a relatively large amount of heat in order to evaporate (that is, it has a large enthalpy of vaporization). The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation). This can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants. The cooling potential for evaporative cooling is dependent on the wet-bulb depression, the difference between dry-bulb temperature and wet-bulb temperatur ...

Cloaca
A cloaca ( ), : cloacae ( or ), or vent, is the rear orifice that serves as the only opening for the digestive (rectum), reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles, birds, cartilaginous fish and a few mammals ( monotremes, afrosoricids, and marsupial moles, etc.) have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have separate orifices for evacuation and reproduction. Excretory openings with analogous purpose in some invertebrates are also sometimes called cloacae. Mating through the cloaca is called cloacal copulation and cloacal kissing. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca'', " sewer, drain" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweat
Perspiration, also known as sweat, is the fluid secreted by sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and Apocrine sweat gland, apocrine glands. The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by excessive body temperature. Apocrine sweat glands are restricted to the armpits and a few other areas of the body and produce an odorless, oily, opaque secretion which then gains its characteristic odor from bacterial decomposition. In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to per hour or per day, but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence, in Temperature, hot weather, or when the individual's muscles hea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek (, ; , ) is an Indo-European languages, Indo-European language, constituting an independent Hellenic languages, Hellenic branch within the Indo-European language family. It is native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the list of languages by first written accounts, longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts ...

Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 20 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ansch� ...

Ventana Wildlife Society
Ventana Wildlife Society (VWS) is a 501(c)(3) non-profit organization founded in 1977 by a group of private citizens to restore endangered species native to central California. VWS has three full-time staff biologists, together with seasonal interns, monitoring, tracking and researching endangered species, songbirds and butterflies. Educational science programs for school children bring youth in touch with nature in their own neighborhoods, or through summer science camps. Since 1997, they have released captive-bred condors into the wild. During the 2020 Dolan Fire, 12 Condors were killed and a research building was destroyed. Programs VWS has four primary areas of focus: * Species recovery: endangered species, including the California condor * Conservation ecology: research, assessment and monitoring of imperiled wildlife * Education and outreach: environmental education * Habitat restoration: rebuilding of lost habitats History In 1977, the Ventana Wildlife Society began by r ...

Bird Ringing
Bird ringing (UK) or bird banding (US) is the attachment of a small, individually numbered metal or plastic tag to the leg or wing of a wild bird to enable individual identification. This helps in keeping track of the movements of the bird and its life history. It is common to take bird measurement, measurements and examine the conditions of feather moult, subcutaneous fat, age indications and sex during capture for ringing. The subsequent recapture, recovery, or observation of the bird can provide information on bird migration, migration, longevity, mortality, population, territoriality, List of feeding behaviours, feeding behaviour, and other aspects that are studied by ornithology, ornithologists. Other methods of marking birds may also be used to allow for field based identification that does not require capture. History The earliest recorded attempts to mark birds were made by Roman army, Roman soldiers. For instance during the Punic Wars in 218 BC a crow was released b ...

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammals. They comprise the extant taxon, extant families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals), with 34 extant species and more than 50 extinct species described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic group (descended from one ancestor). Pinnipeds belong to the suborder Caniformia of the order Carnivora; their closest living relatives are musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal seal to the and southern elephant seal. Several species exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
