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 ...
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.
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.
Most of us learned about nature and animals in school. ... Ecologists have found that while barn owls are normally monogamous – mating with only one partner for life – about 25% of mating ...
A monogamous mating system is one in which individuals form long-lasting pairs and cooperate in raising offspring. These pairs may last for a lifetime, such as in pigeons, [6] or it may occasionally change from one mating season to another, such as in emperor penguins. [7]
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.
Therefore, mating before each oviposition is not necessary. There is no significant overall benefit for females in multiple matings; large females are at an advantage due to their ability to resist unnecessary matings. [21] As a result of multiple male mating, multiple paternities were observed in species as a result of convenience polyandry. [4]
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.
