Monogamy in mammals is rather rare, only occurring in 3–9% of these species. [3] [4] [5] A larger percentage of avian species are known to have monogamous relationships (about 90%), [6] but most avian species practice social but not genetic monogamy in contrast to what was previously assumed by researchers.

Gorilla Great reed warbler. When two animals mate, they both share an interest in the success of the offspring, though often to different extremes. Unless the male and female are perfectly monogamous, meaning that they mate for life and take no other partners, even after the original mate's death, the amount of parental care will vary. [7]
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."
The song can be used to identify not only which species of gibbon is singing, but also the area from which it comes. [25] Gibbons often retain the same mate for life, although they do not always remain sexually monogamous. In addition to extra-pair copulations, pair-bonded gibbons occasionally "divorce".
Orians predicted that animals exhibiting resource defence polygyny, such as the fish Neolamprologus pulcher would fit to this model when living in successive habitats, where territory quality is very variable. Using the territory quality to decide whether to pursue a monogamous or polygynous mating relationship.
These birds are monogamous and mate for life. They may spend a few months out to sea apart, but they come back to the same place every year to breed and nest. ... The post The Unusual Galapagos ...
The following are some of the mating systems generally recognized in animals: Monogamy: One male and one female have an exclusive mating relationship. The term "pair bonding" often implies this. This is associated with one-male, one-female group compositions. There are two types of monogamy: type 1, which is facultative, and type 2, which is ...
“Monogamous people may have a similar bias because they might worry that an ambiamorous person will be interested in non-monogamy again at some point in their lives,” she explains.
