A mineral lick (also known as a salt lick) is a place where animals can go to lick essential mineral nutrients from a deposit of salts and other minerals. Mineral licks can be naturally occurring or artificial (such as blocks of salt that farmers place in pastures for livestock to lick). Natural licks are common, and they provide essential elements such as phosphorus and the biometals (sodium, calcium, iron, zinc, and trace elements) required for bone, muscle and other growth in herbivorous mammals such as deer, moose, elephants, hippos, rhinos, giraffes, zebras, wildebeests, tapirs, woodchucks, fox squirrels, mountain goats, porcupines, and frugivorous bats. [1] Such licks are especially important in ecosystems such as tropical rainforests and grasslands with poor general availability of nutrients. Harsh weather exposes salty mineral deposits that draw animals from miles away for a taste of needed nutrients. It is thought that certain fauna can detect calcium in salt licks. [2]
Many animals regularly visit mineral licks to consume clay, supplementing their diet with nutrients and minerals. In tropical bats, lick visitation is associated with a diet based on wild figs ( Ficus ), which have very low levels of sodium, [3] [4] and licks are mostly used by females that are pregnant or lactating. [5]
Some animals require the minerals at these sites not for nutrition, but to ward off the effects of secondary compounds that are included in the arsenal of plant defences against herbivory. [6] [ failed verification ] The minerals of these sites usually contain calcium, magnesium, sulfur, phosphorus, potassium, and sodium. [7] [8] [9] [10] Mineral lick sites play a critical role in the ecology and diversity of organisms that visit these sites, but little is still understood about the dietary benefits.
The paths animals made to natural mineral licks and watering holes became the hunting paths predators and early humans used for hunting. It is hypothesized that these salt and water paths became trails and later roads for early humans. [11]
Nonetheless, many studies have identified other uses and nutritional benefits from other micronutrients that exist at these sites, including selenium, cobalt and/or molybdenum. [12] [13] In addition to the utilization of mineral licks, many animals suffer from traffic collisions as they gather to lick salts accumulated on road surfaces. Animals also consume soil (geophagy) to obtain minerals, such as moose from Canada mining for minerals from the root wads of fallen trees. [14] [15]
Artificial salt licks are used in the husbandry of livestock and to attract or maintain wildlife, whether it be for viewing, photography, farming, or hunting purposes. [16] Maintaining artificial salt licks as a form of baiting is illegal in some states in the United States, but legal in others. [10] : 413 Inadvertent salt licks may lead to unintended wildlife-human interactions. [17]
The indigenous peoples of the Americas and the longhunter watched salt licks to hunt game. Many became well-known, including Bledsoe Lick in Sumner County, Tennessee; the Blue Lick in central Kentucky; 'Great Buffalo Lick' in Kanawha Salines, now present-day Malden, West Virginia; the French Lick in southern Indiana; and the Blackwater Lick in Blackwater, Lee County, Virginia.

In Norse mythology, before the creation of the world, the divine cow Auðumbla licked salty ice for three days and uncovered Búri, ancestor of the gods and grandfather of Odin. On the first day as Auðumbla licked, Buri's hair appeared from the ice, on the second day his head, and the third his body. [19]
Ash is the solid remnants of fires. Specifically, ash refers to all non-aqueous, non-gaseous residues that remain after something burns. In analytical chemistry, to analyse the mineral and metal content of chemical samples, ash is the non-gaseous, non-liquid residue after complete combustion.
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods.
Macaws are a group of New World parrots that are long-tailed and often colorful, in the tribe Arini. They are popular in aviculture or as companion parrots, although there are conservation concerns about several species in the wild.
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host.
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions in a solution. In soils, it is measured in a slurry of soil mixed with water, and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils and very strongly alkaline soils are rare.
In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. Minerals are one of the four groups of essential nutrients; the others are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. The remaining minerals are called "trace elements". The generally accepted trace elements are iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine, selenium, and bromine; there is some evidence that there may be more.
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite. This is in accordance with Justus von Liebig's law of the minimum. The total essential plant nutrients include seventeen different elements: carbon, oxygen and hydrogen which are absorbed from the air, whereas other nutrients including nitrogen are typically obtained from the soil.
The New World leaf-nosed bats (Phyllostomidae) are bats found from southern North America to South America, specifically from the Southwest United States to northern Argentina. They are ecologically the most varied and diverse family within the order Chiroptera. Most species are insectivorous, but the phyllostomid bats include within their number true predatory species and frugivores. For example, the spectral bat, the largest bat in the Americas, eats vertebrate prey, including small, dove-sized birds. Members of this family have evolved to use food groups such as fruit, nectar, pollen, insects, frogs, other bats, and small vertebrates, and in the case of the vampire bats, even blood.
Geophagia, also known as geophagy, is the intentional practice of consuming earth or soil-like substances such as clay, chalk, or termite mounds. It is a behavioural adaptation that occurs in many non-human animals and has been documented in more than 100 primate species. Geophagy in non-human primates is primarily used for protection from parasites, to provide mineral supplements and to help metabolize toxic compounds from leaves. Geophagy also occurs in humans and is most commonly reported among children and pregnant women.
Organic fertilizers are fertilizers that are naturally produced. Fertilizers are materials that can be added to soil or plants, in order to provide nutrients and sustain growth. Typical organic fertilizers include all animal waste including meat processing waste, manure, slurry, and guano; plus plant based fertilizers such as compost; and biosolids. Inorganic "organic fertilizers" include minerals and ash. Organic refers to the Principles of Organic Agriculture, which determines whether a fertilizer can be used for commercial organic agriculture, not whether the fertilizer consists of organic compounds.
The Jamaican, common, or Mexican fruit bat is a frugivorous bat species native to the Neotropics.
The pallid bat is a species of bat that ranges from western Canada to central Mexico. It is the sole species of its genus and is closely related to Van Gelder's bat, which is sometimes included in Antrozous. Although it has in the past been placed in its own subfamily (Antrozoinae) or even family (Antrozoidae), it is now considered part of the subfamily Vespertilioninae and the tribe Antrozoini.
The little yellow-shouldered bat is a bat species from South and Central America. It is a frugivore and an effective seed disperser.
Osteophagy is the practice in which animals, usually herbivores, consume bones. Most vegetation around the world lacks sufficient amounts of phosphate. Phosphorus is an essential mineral for all animals, as it plays a major role in the formation of the skeletal system, and is necessary for many biological processes including: energy metabolism, protein synthesis, cell signaling, and lactation. Phosphate deficiencies can cause physiological side effects, especially pertaining to the reproductive system, as well as side effects of delayed growth and failure to regenerate new bone. The importance of having sufficient amounts of phosphorus further resides in the physiological importance of maintaining a proper phosphorus to calcium ratio. Having a Ca:P ratio of 2:1 is important for the absorption of these minerals, as deviations from this optimal ratio can inhibit their absorption. Dietary calcium and phosphorus ratio, along with vitamin D, regulates bone mineralization and turnover by affecting calcium and phosphorus transport and absorption in the intestine.
The Manu parrotlet or Amazonian parrotlet is a species of parrotlet native to the western Amazon basin, from southern Peru to northwest Bolivia. It is found in lowland forests near bamboo and rivers.
The greater short-nosed fruit bat, or short-nosed Indian fruit bat, is a species of megabat in the family Pteropodidae found in South and Southeast Asia.
Specific appetite, also known as specific hunger, is a drive to eat foods with specific flavors or other characteristics.
Sodium ions are necessary in small amounts for some types of plants, but sodium as a nutrient is more generally needed in larger amounts by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance. In animals, sodium ions are necessary for the aforementioned functions and for heart activity and certain metabolic functions. The health effects of salt reflect what happens when the body has too much or too little sodium. Characteristic concentrations of sodium in model organisms are: 10 mM in E. coli, 30 mM in budding yeast, 10 mM in mammalian cell and 100 mM in blood plasma.
The Macaw Society is a long-term research project on the ecology and conservation of macaws and parrots under the direction of Donald Brightsmith and Gabriela Vigo of the Schubot Center for Avian Health at the Texas A&M University. The project has been working with wildlife and local communities since 1989. The long-term research and monitoring have provided many insights into various aspects of parrot and wildlife of south-eastern Peru. Macaws are among the most effective flagship species for ecosystem conservation in the Amazonian rainforest.
