Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host ) and parasitoidism (which always does, eventually).
The term predation rate refers to the frequency with which an organism captures and consumes its prey in an ecosystem. Coupled with the kill rate, the predation rate drives the population dynamics of predation. [1]. This statistic is related to Predator–prey dynamics and may be influenced by several factors.
For example, exploitative interactions between a predator and prey can result in the extinction of the victim (the prey, in this case), as the predator, by definition, kills the prey, and thus reduces its population. [2] Another effect of these interactions is in the coevolutionary "hot" and "cold spots" put forth by geographic mosaic theory ...
Prey that require more handling time than they are worth in terms of nutritional value leads to hyperpredation. In severe circumstances, predators that fed on such prey went extinct. [ 3 ] [ 4 ] Introduced Eastern cottontails cause an apparent competition with the European hare , as a result this along with the red fox being their main predator ...
The term raptor is derived from the Latin word rapio, meaning "to seize or take by force". [8] The common names for various birds of prey are based on structure, but many of the traditional names do not reflect the evolutionary relationships between the groups.

Mobbing is the harassing of a predator by many prey animals. Mobbing is usually done to protect the young in social colonies. For example, red colobus monkeys exhibit mobbing when threatened by chimpanzees, a common predator. The male red colobus monkeys group together and place themselves between predators and the group's females and juveniles.
The definition of preference will therefore impact the understanding of switching. The most common definition of preference is the relationship between the ratio of prey in the environment and the ratio of prey in a predator's diet. It has been independently proposed a number of times and is described by the equation:
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
