The central part of the definition of a species is the members’ ability to produce viable offspring. Hence, attempting to mate with members of a different species is not an advantageous behavioural trait in the context of reproductive success.

Β 

Courtship behaviours also allow organisms to approach one another without aggression or invasion of their personal space.

Β 

Sometimes the outcome of courtship behaviour is the formation of a pair bond. This bond results in a better reproductive success, due to the increased survival probability of the offspring. In some species this is the case, while in others it isn’t. This is tightly related to a specific organism’s physiology. Fish are able to lay a huge number of eggs, while pigeons only lay one or two. Therefore, it is more likely that pigeons would…
