Australian Raven
The Australian raven (''Corvus coronoides'') is a passerine Corvidae, corvid bird native to Australia. Measuring in length, it has an all-black plumage, beak and mouth, as well as strong, greyish-black legs and feet. The upperparts of its body are glossy, with a purple-blue, greenish sheen; its black feathers have grey bases. The Australian raven is distinguished from the Australian crow, and other related corvids, by its long chest feathers, or Hackles, throat hackles, which are prominent in mature birds. Older individuals and Juvenile (organism), subadults have white Iris (anatomy), irises, while the younger birds' eyes display blue inner rims; Hatchling, hatchlings and young birds have brown, dark irises until about fifteen months of age, at which point their irises become hazel-coloured, with an inner blue rim around each pupil, this lasting until they are roughly 2.5 to 3 years of age. Nicholas Aylward Vigors and Thomas Horsfield described the Australian raven in 1827, its s ...

Carrion Crow
The carrion crow (''Corvus corone'') is a passerine bird of the family Corvidae, native to western Europe and the eastern Palearctic. Taxonomy and systematics The carrion crow was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', and it still bears its original name of ''Corvus corone''. The binomial name is derived from the Latin , "raven", and Greek , "crow". The hooded crow (''Corvus cornix''), formerly regarded as a subspecies, has been split off as a separate species, and there is some discussion whether the eastern carrion crow (''C. c. orientalis'') is distinct enough to warrant specific status; the two taxa are well separated, and it has been proposed they could have evolved independently in the wetter, maritime regions at the opposite ends of the Eurasian landmass.Madge, Steve & Burn, Hilary (1994): ''Crows and jays: a guide to the crows, jays and magpies of the world''.

Placental Expulsion
Placental expulsion (also called afterbirth) occurs when the placenta comes out of the birth canal after childbirth. The time between the expulsion of the baby and the expulsion of the placenta is called the third stage of labor. The third stage of labor can be managed actively with several standard procedures, or it can be managed expectantly, with physiological management or passive management. The latter allows for the placenta to be expelled without medical assistance. Although uncommon, in some countries, such as the United States, Germany, France, Australia, and the United Kingdom, the placenta is kept and consumed by the mother over the weeks following the birth. This practice is termed human placentophagy and can be harmful. Physiology Hormone induction of placental separation As the fetal hypothalamus matures, the activation of the hypothalamic–pituitary–adrenal (HPA) axis initiates labor through two hormonal mechanisms. The end pathway of both mechanisms lead ...

Sheep Farming
Sheep farming or sheep husbandry is the raising and breeding of domestic sheep. It is a branch of animal husbandry. Sheep are raised principally for their meat (lamb and mutton), milk (sheep's milk), and fiber (wool). They also yield sheepskin and parchment. Sheep can be raised in a range of temperate climates, including arid zones near the equator and other torrid zones. Farmers build fences, housing, shearing sheds, and other facilities on their property, such as for water, feed, transport, and pest control. Most farms are managed so sheep can graze pastures, sometimes under the control of a shepherd or sheep dog. Farmers can select from various breeds suitable for their region and market conditions. When the farmer sees that a ewe (female adult) is showing signs of heat or estrus, they can organise for mating with males. Newborn lambs are typically subjected to lamb marking, which involves tail docking, mulesing, earmarking, and males may be castrated. Sheep producti ...

Food Waste
The causes of food going uneaten are numerous and occur throughout the food system, during food production, production, food processing, processing, Food distribution, distribution, Grocery store, retail and food service sales, and Social class differences in food consumption, consumption. Overall, about one-third of the world's food is thrown away. A similar amount is lost on top of that by feeding human-edible food to farm animals (the net effect wastes an estimated 1144 kcal/person/day). A 2021 meta-analysis, that did not include food lost during production, by the United Nations Environment Programme found that food waste was a challenge in all countries at all levels of economic development. The analysis estimated that global food waste was 931 million tonnes of food waste (about 121 kg per capita) across three sectors: 61 percent from Household waste, households, 26 percent from Foodservice, food service and 13 percent from Food retailer, retail. Food loss and waste ...

Opportunism
300px, ''Opportunity Seized, Opportunity Missed'', engraving by Theodoor Galle, 1605 Opportunism is the practice of taking advantage of circumstances — with little regard for principles or with what the consequences are for others. Opportunist actions are expedient actions guided primarily by self-interested motives. The term can be applied to individual humans and living organisms, groups, organizations, styles, behaviors and trends. Opportunism or "opportunistic behaviour" is an important concept in such fields of study as biology, transaction cost economics, game theory, ethics, psychology, sociology and politics. Etymology In the early 19th century, the term "opportunist" as a noun or adjective was already known and used in several European languages, but initially, it rarely referred to political processes or to a political tendency. The English term "opportunism" is possibly borrowed originally from the Italian expression ''opportunismo''. In 19th-century Itali ...

Omnivorous
An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms ( Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. ...
