Bluegill sunfish males use one of three strategies in trying to gain access to females and mate. Each male only carries out only one of the three strategies: territorial male, sneaker male or female mimic. While the territorial males have the highest reproductive success relative to the other males, some males are not large enough to successfully compete with other territorial males and adopt an alternative strategy, where they gain at least some reproductive success. This is an example of

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.
