Extra-pair copulation

 Extra-pair copulation (EPC) is a mating behaviour in monogamous species. 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.


 

Extra-pair copulation is common in birds. For example, zebra finches, although socially monogamous, are not sexually monogamous and hence do engage in extra-pair courtship and attempts at copulation.
