Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases ...
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.
Not all socially monogamous species exhibit pair bonding, but all pair bonding animals practice social monogamy. These characteristics aid in identifying a species as being socially monogamous. At the biological level, social monogamy affects the neurobiology of the organism through hormone pathways such as vasopressin and oxytocin. [13]
In both of these species, males and females are monogamous, pair-bonded, and exhibit bi-parental care for their offspring. [25] [42] [24] The social group in both these species consists of female and male parents along with their offspring. [43] [24] Males in these species serve as the primary caregivers and play a major role in infant survival ...
The type of mating system may influence which sex provides care. In monogamous species that establish long-term pair-bonds, parents are likely to cooperate in caring for their offspring. In polyandrous mating systems, paternal or male-only care tends to evolve. Conversely, polygynous mating systems are associated with little or no male ...
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 ...
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 is the practice of having only one sexual partner at any one time, forming a long-term bond and combining efforts to raise offspring together; mating outside this pairing is extra-pair copulation. [1] Across the animal kingdom, extra-pair copulation is common in monogamous species, and only a very few pair-bonded species are thought to ...
