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).
A familiar example is the broken-wing display seen in nesting waders, plovers and doves such as the mourning dove. In this display, a bird walks away from its nest with one wing dragging on the ground. It seems to be an easy target, thus distracting the predator's attention away from the nest.
The traditional culture of the Southern United States has been called a "culture of honor", that is, a culture where people avoid intentionally offending others, and maintain a reputation for not accepting improper conduct by others.
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
Escape response in Antarctic krill.. Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation.It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator.
For example, yellow-eyed juncos spend more time scanning for predators when a potential predator, a Harris's hawk (Parabuteo unicinctus), is present compared to when the hawk is absent. [ 5 ] Another factor that influences vigilance is the benefit that is expected from foraging in the absence of predation. [ 4 ]
Hyperpredation has been recorded in an ecosystem involving a bird (native prey), a cat (alien predator), and a rabbit (alien prey). Hyperpredation, also known as hypopredation, is when a generalist predator increases its predation pressure as a result of the introduction of a substitute prey. [1]
An extensively studied example is the fiddler crab. When exposed to a predator, fiddler crabs move in ways that are consistent with the selfish herd theory. [5] Dispersed groups are more likely to form an aggregate when subjected to danger and crabs attempt to run toward the center of a forming group. [12] Selfish herd behavior is seen also in:
