Before and after social pairing and mating occurs, bird song is mainly dedicated to territorial defense. This behavior is a sexually selected trait because it ensures defense of the female who is rearing her offspring. [9] There is also some evidence that vocal amplitude effects male-male competition in such species as the great tit. Most ...
Lekking behaviour in the Clusiid fly Paraclusia tigrina. The main benefit for both sexes is mating success. For males, the costs stem from females' preferences. The traits that are selected for may be energetically costly to maintain and may cause increased predation.
Both partners perform the mutual behaviour at the same time in order to improve partner recognition, organised nesting sites and roles, and to strengthen the pair bond of the two species. [92] Bowing is the final observed courtship behaviour observed in most penguin species. This behaviour is characterized when the male and female bow towards ...

They are renowned for their unique courtship behaviour, where males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate.

There is experimental evidence that implies the female may also release pheromones that attract the male; this is an instance of chemical display behaviour that plays a large role in animal communication. [5] Auditory courtship behavior is seen in fruit flies like A. suspensa when they perform calling and pre-copulatory songs before mating ...
