Monogamy as a mating system in animals has been thought to lower levels of some pre and post copulatory competition methods. [15] [17] [24] Because of this reduction in competition in some instances the regulation of certain morphological characteristics may be lowered. This would result in a vast variety of morphological and physiological ...
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances.
These species do, however, exhibit monogamous mating systems presumably due to high dispersal rates. Komers and Brotherton (1997) indicated that there is a significant correlation between mating systems and grouping patterns in these species. Furthermore, monogamous mating system and female dispersion are found to be closely related.
Close to ninety percent [3] of known avian species are monogamous, compared to five percent of known mammalian species.The majority of monogamous avians form long-term pair bonds which typically result in seasonal mating: these species breed with a single partner, raise their young, and then pair up with a new mate to repeat the cycle during the next season.
Ecologists have found that while barn owls are normally monogamous – mating with only one partner for life – about 25% of mating pairs “divorce”, and move on to new partners.
Sexual monogamy is also rare among animals. Many socially monogamous species engage in extra-pair copulations, making them sexually non-monogamous. For example, while over 90% of birds are socially monogamous, "on average, 30% or more of the baby birds in any nest [are] sired by someone other than the resident male."
Monogamy, or a monogamous mating system, is when one adult male and one adult female have a preferential partner for copulation. [1] There is a long-term temporal element to this category of mating system (longer than one year or one seasonal cycle) and offspring resulting from this mating system will belong to the pair. [ 8 ]
After mating, the birds build a nest on the ground. The female lays one egg and both parents incubate the egg. After the chick hatches, it goes to live in a nursery with other chicks.
