A courtship display is a set of display behaviors in which an animal, usually a male, attempts to attract a mate; the mate exercises choice, so sexual selection acts on the display. These behaviors often include ritualized movement (" dances "), vocalizations , mechanical sound production, or displays of beauty, strength, or agonistic ability .
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 ...
The courtship and mating behavior of males and females are regulated largely by hormones throughout a bird's lifetime. [76] Activational hormones occur during puberty and adulthood and serve to 'activate' certain behaviors when appropriate, such as territoriality during breeding season. [ 76 ]
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 ...
Males of certain species have evolved mating behaviors in which they forcefully attempt to mate with and inseminate females, often employing grasping techniques. These male grasping devices exist to increase the duration of copulation and restrict females from mating with other males. They are in some ways a form of mate guarding. While some ...
The black swan, Cygnus atratus is a large waterbird which breeds mainly in the southeast and southwest regions of Australia.An estimated one-quarter of all black swans pairings are homosexual and they steal nests, or form temporary threesomes with females to obtain eggs, driving away the female after she lays the eggs.
The male bat uses its penis more like an arm to move a protective membrane away from the female bat’s vulva, according to a study published Monday in the journal Current Biology.
Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
