Soil erosion is the denudation of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes.
Amazon parrots are parrots in the genus Amazona. They are medium-sized, short-tailed parrots native to the Americas, with their range extending from South America to Mexico and the Caribbean. Amazona is one of the 92 genera of parrots that make up the order Psittaciformes and is in the family Psittacidae, one of three families of true parrots. It contains about thirty species. Most amazons are predominantly green, with accenting colors that depend on the species, and they can be quite vivid. They feed primarily on seeds, nuts, and fruits, supplemented by leafy matter.
Pica is the eating or craving of things that are not food. It can be a disorder in itself or a sign of other cultural or medical phenomena. The ingested or craved substance may be biological, natural or manmade. The term was drawn directly from the medieval Latin word for magpie, a bird subject to much folklore regarding its opportunistic feeding behaviors.
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 eating, preening, manipulating objects, killing prey, fighting, probing for food, 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, anuran tadpoles, monotremes, sirens, pufferfish, billfishes and cephalopods.
In zoology, a crepuscular animal is one that is active primarily during the twilight period, being matutinal, vespertine, or both. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daylight and of darkness, respectively. Some crepuscular animals may also be active by moonlight or during an overcast day. Matutinal animals are active only before sunrise, and vespertine only after sunset.
Clinical neuropsychology is a sub-field of psychology concerned with the applied science of brain-behaviour relationships. Clinical neuropsychologists use this knowledge in the assessment, diagnosis, treatment, and or rehabilitation of patients across the lifespan with neurological, medical, neurodevelopmental and psychiatric conditions, as well as other cognitive and learning disorders. The branch of neuropsychology associated with children and young people is pediatric neuropsychology.
The Cuban amazon also known as Cuban parrot or the rose-throated parrot, is a medium-sized mainly green parrot found in woodlands and dry forests of Cuba, the Bahamas and Cayman Islands in the Caribbean. Although they have been observed in the wild in Puerto Rico, they are probably the result of escaped pets, and no reproduction has been recorded.
The thick-billed parrots are stocky brilliant green Neotropical parrots with heavy black beaks of genus Rhynchopsitta of thick billed macaw-like parrots. The genus comprises two extant species, the thick-billed parrot and the maroon-fronted parrot, as well as an extinct species from the Late Pleistocene in Mexico. The two extant taxa were formerly considered conspecific; they have become rare and are restricted to a few small areas in northern Mexico. The range of the thick-billed parrot formerly extended into the southwestern United States; attempts at reintroduction have been unsuccessful so far.
The common poorwill is a nocturnal bird of the family Caprimulgidae, the nightjars. It is found from British Columbia and southeastern Alberta, through the western United States to northern Mexico. The bird's habitat is dry, open areas with grasses or shrubs, and even stony desert slopes with very little vegetation.
The white-crowned parrot, also known as the white-crowned pionus in aviculture, is a small parrot which is a resident breeding species from eastern Mexico to western Panama.
Finsch's pygmy parrot, also known as the emerald pygmy parrot and green pygmy parrot, is a member of parrot family Psittacidae inhabiting tropical rainforest regions of islands in Papua New Guinea, the Solomon Islands, and the Bismarck Archipelago.
A penis is the primary sexual organ that male animals use to inseminate females during copulation. Such organs occur in many animals, both vertebrate and invertebrate, but males do not bear a penis in every animal species, and in those species in which the male does bear a so-called penis, the penises in the various species are not necessarily homologous.
The New Zealand parrot family, Strigopidae, consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, and probably the fossil Heracles. The genus Nestor consists of the kea, kākā, Norfolk kākā and Chatham kākā, while the genus Strigops contains the iconic kākāpō. All extant species are endemic to New Zealand. The species of the genus Nelepsittacus were endemics of the main islands, while the two extinct species of the genus Nestor were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island.
Parrots, also known as psittacines, are birds of the roughly 398 species in 92 genera comprising the order Psittaciformes, found mostly in tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea, the Cacatuoidea (cockatoos), and the Strigopoidea. One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia.

He later was a founder of the company HBD International, Inc. which manufactures the product line Harrison's Bird Foods. Harrison also was a main contributor and editor of several of the field's earliest and most well-known texts including, Avian Medicine: Principles and Applications and Clinical Avian Medicine. and the Avian Veterinary Compendium.
This is a list of encyclopedias as well as encyclopedic and biographical dictionaries published on the subject of biology in any language.
The following is a glossary of common English language terms used in the description of birds—warm-blooded vertebrates of the class Aves and the only living dinosaurs, characterized by feathers, the ability to fly in all but the approximately 60 extant species of flightless birds, toothless, beakedjaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart and a strong yet lightweight skeleton.
Charles Street is a street in the West Village neighborhood of Manhattan in New York City. It runs east to west from Greenwich Avenue to West Street. The street was named after Charles Christopher Amos, who owned the parcel the street passed through. Amos is also the namesake of Christopher Street, two blocks to the south, and the former Amos Street, which is now West 10th Street. Charles Lane is a one-block alley located between Charles and Perry Streets and Washington and West Streets. From 1866 to 1936, the section of Charles Street between Bleecker Street and West 4th Street was called Van Ness Place after a farm, owned by the Van Ness family, which had occupied the square bounded by Bleecker, West 4th, Charles and Perry Streets until 1865.
Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check. Feathers contribute significantly to a bird's insulation, waterproofing and aerodynamic flight, and so are vital to its survival. Because of this, birds spend considerable time each day maintaining their feathers, primarily through preening. Several actions make up preening behaviour. Birds fluff up and shake their feathers, which helps to "rezip" feather barbules that have become unhooked. Using their beaks, they gather preen oil from a gland at the base of their tail and distribute this oil through their feathers. They draw each contour feather through their bill, nibbling it from base to tip.
