Yellow-faced Parrotlet
The yellow-faced parrotlet (''Forpus xanthops'') is a species of parrot in the family Psittacidae. Description Yellow-faced parrotlets are about long and weigh about . Their bodies are mostly dark or olive green with gray washes on the nape and mantle and yellow-green underparts, and foreheads, crown, cheeks, and throat are bright yellow. A gray-green stripe extends backwards from each eye. Eyes are dark brown and feet and lower mandibles are light peach. The upper mandible is light peach with a gray or darker brown base. Yellow-faced parrotlets are sexually dimorphic: males have bright blue lower backs, tail, secondary, and underwing coverts, and inner primary feathers. Females' blue feathers are lighter on their backs and rumps, with blue-tinged green coverts, secondaries, and primaries. Juveniles of the species look similar to adults, but are duller and have fewer yellow feathers and an entirely peach beak. Like all parrots, yellow-faced parrotlets exhibit zygodactyly, mean ...

Osbert Salvin
Osbert Salvin FRS (25 February 1835 – 1 June 1898) was an English naturalist, ornithologist, and herpetologist best known for co-authoring ''Biologia Centrali-Americana'' (1879–1915) with Frederick DuCane Godman. This was a 52 volume encyclopedia on the natural history of Central America. Biography Osbert Salvin was born in Finchley, north London, the second son of the architect Anthony Salvin, of Hawksfold, Sussex. He was educated at Westminster and Trinity Hall, Cambridge, taking his degree in 1857. Shortly afterwards he accompanied his second cousin by marriage, Henry Baker Tristram, in a natural history exploration of Tunisia and eastern Algeria. Their account of this trip was published in ''The Ibis'' in 1859 and 1860. In the autumn of 1857, he made the first of several visits to Guatemala, returning there with Frederick DuCane Godman in 1861. It was during this journey that the ''Biologia Centrali-Americana'' was planned. In 1871 Salvin became editor of ''The Ibis'' ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Breeding Program
A breeding program is the planned breeding of a group of animals or plants, usually involving at least several individuals and extending over several generations. There are a couple of breeding methods, such as artificial (which is man made) and natural (it occurs on its own). According to the Dutch State Secretary of Economic Affairs the delivery of young animals is important for the natural behavior of the mother, the herd and is desirable from a veterinary perspective. Breeding programs are commonly employed in several fields where humans wish to change the characteristics of their animals' offspring through careful selection of breeding partners: *Dog and cat fanciers may coordinate a breeding program to raise the probability of an animal's litter producing a championship-caliber animal. *Horse breeders try to produce fast racehorses through breeding programs. *Conservationists use breeding programs to try to help the recovery of endangered species by preserving the exis ...

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Clutch (eggs)
__NOTOC__ A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. The act of putting one's hand in a nest to remove eggs is known as "dipping the clutch". Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundan ...

Bird Vocalization
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations). Definition The distinction between songs and calls is based upon complexity, length, and context. Songs are longer and more complex and are associated with territory and courtship and mating, while calls tend to serve such functions as alarms or keeping members of a flock in contact. Other authorities such as Howell and Webb (1995) make the distinction based on function, so that short vocalizations, such as those of pigeons, and even non-vocal sounds, such as the drumming of woodpeckers and the "winnowing" of snipes' wings in display flight, are considered songs. Still others require song to have syllabic diversity and temporal regularity akin to the repetitive and transformative patte ...

Sociality
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies. Sociality is a survival response to evolutionary pressures. For example, when a mother wasp stays near her larvae in the nest, parasites are less likely to eat the larvae. Biologists suspect that pressures from parasites and other predators Natural selection, selected this behavior in wasps of the Family (biology), family Vespidae. This wasp behaviour evidences the most fundamental characteristic of animal sociality: parental investment. Parental investment is any expenditure of resources (time, energy, social capital) to benefit one's offspring. Parental investment detracts from a parent's capacity to invest in future reproduction and aid to Family, kin (including other offspring). An animal that cares for its young but shows no other sociality traits is said to be ''subsocial''. An animal that exhibits a high degree of social ...

Environmental Law
Environmental law is a collective term encompassing aspects of the law that provide protection to the environment. A related but distinct set of regulatory regimes, now strongly influenced by environmental legal principles, focus on the management of specific natural resources, such as forests, minerals, or fisheries. Other areas, such as environmental impact assessment, may not fit neatly into either category, but are nonetheless important components of environmental law. History Early examples of legal enactments designed to consciously preserve the environment, for its own sake or human enjoyment, are found throughout history. In the common law, the primary protection was found in the law of nuisance, but this only allowed for private actions for damages or injunctions if there was harm to land. Thus, smells emanating from pigsties, strict liability against dumping rubbish, or damage from exploding dams. Private enforcement, however, was limited and found to be woefully in ...

Wild Bird Conservation Act
The international trade in parrots is a lucrative enterprise, and forms an important part of the international wildlife trade. As parrots have become increasingly endangered, many countries have placed restrictions on the trade and/or prohibited the trade altogether. Despite the restriction on trade in many countries however, the market still operates both legally and illegally. Approximately 2,600 of the more than 9,600 bird species in existence are subject to trade, FAO. 2011.
