thumb|right|A brooding white tern (Gygis alba). Broodiness is the action or behavioral tendency to sit on a clutch of eggs to incubate them, often requiring the non-expression of many other behaviors including feeding and drinking. Being broody has been defined as "Being in a state of readiness to brood eggs that is characterized by cessation of laying and by marked changes in behavior and physiology". Broodiness is usually associated with female birds, although males of some bird species become broody and some non-avian animals also show broodiness.

A graminivore is a herbivorous animal that feeds primarily on grass, specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing. These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose, which is abundant in fibrous plant matter and more difficult to break down for many other animals. As such, they have specialized enzymes to aid in digestion and in some cases symbiotic bacteria that live in their digestive track and "assist" with the digestive process through fermentation as the matter trav

It occurs among both carnivorous and herbiviorous animals. Among carnivores, it is an ecological niche where a species can extract more nutrition from the same food resources than competitors can, by being able to crack apart and digest bones. These adaptions may be dental, as in spotted hyenas and wolverines, or physiological and behavioral, as in bearded vultures. Among non-carnivores, the word refers to a behavior where individuals of a species cons

A gummivore is an omnivorous animal whose diet consists primarily of the gums and saps of trees (about 90%) and insects for protein. Notable gummivores include arboreal, terrestrial primates like certain marmosets and lemurs. These animals that live off of the injuries of trees live from about 8m off of the ground up to the canopies. The feeding habit of gummivores is gummivory.

thumb|upright=1.35|A buffalo wallowing Wallowing in animals is comfort behaviour during which an animal rolls about or lies in mud, water or snow. Some definitions include rolling about in dust, however, in ethology this is usually referred to as dust bathing. Wallowing is often combined with other behaviours to fulfil its purpose; for example, elephants will often blow dirt over themselves after wallowing to create a thicker "coating", or pigs will allow the mud to dry before rubbing themselves on a tree or rock to remove ectoparasites stuck in the mud.

Tripedalism (from the Latin tri = three + ped = foot) is locomotion by the use of three limbs. Real-world tripedalism is rare, in contrast to the common bipedalism of two-legged animals and quadrupedalism of four-legged animals. Bilateral symmetry seems to have become entrenched very early in evolution, appearing even before appendages like legs, fins or flippers had evolved.

A pugmark is a footprint left by a wild animal. The distinctive pugmark of an individual species is useful for identification. "Pug" means foot in Hindi (Sanskrit पद् "pad"; Greek πούς "poús"). thumb|right|300px|An image of a thylacine pugmark Pugmark tracking is a technique used by wildlife conservationists to identify the distribution of species. For some species, such as tigers, pugmark tracking is now considered to be an unreliable method of determining an area's total animal population, leading to the rise in the use of alternative techniques to count populations, such as photographic ca
