To counter this, though, some females will dedicate hours to watch over their partners, scaring away any females that may come close. Similarly, they tend to mate frequently, both to weaken the male so that he cannot show interest in other females, and to increase the chances of fertility!
Often, males will leave their home territory after their primary female mate has laid her first eggs. Then, he will create a second territory, to attract new females to him. However, the male tends to often return to the first female to care for her and his children, abandoning his taudry affair with another woman. Cases have also been known where the male has been found to care for both females; ooh ladies, can you imagine the catfights?!
As you can see here, we have a strictly monogamous bird, a despicable player and finally, one species that enjoys a bit of a wild love life. There are many species that conform to these similar patterns; try observing a few and seeing if you can spot any similar patterns!
