Male pigeons, Columba livia, employ intense mate guarding and frequent copulation apparently as strategies to ensure their paternity. The aim of this study was to investigate the benefits to females of mate guarding by males and frequent copulation. Field observations showed that females initiated the majority of copulations and females that solicited copulations more frequently were guarded more closely by their partner. Experimental removal of guarding male partners showed that: (1) unguarded, fertile females suffered increased harassment from extrapair males which reduced their foraging efficiency; and (2) unguarded, fertile females did not seek copulations with extrapair males. Various explanations for frequent pair copulation initiated by females are discussed and we conclude that female pigeons trade pair copulations for protection (mate guarding) against sexual harassment from other males.

雄性家鸽（Columba livia）会采取强烈的配偶守护行为和频繁交配的策略，显然是为了确保自己的父权。本研究的目的是调查雄性配偶守护行为和频繁交配给雌性带来的益处。野外观察表明，大多数交配由雌性发起，且更频繁主动求偶的雌性会受到伴侣更严密的守护。通过实验移除守护的雄性伴侣发现：（1）未受守护的可育雌性交配时遭受额外雄性骚扰的情况增多，这降低了它们的觅食效率；（2）未受守护的可育雌性不会寻求与额外雄性交配。文中讨论了雌性发起频繁配偶交配行为的各种解释，我们得出结论，雌性家鸽通过配偶交配来换取免受其他雄性性骚扰的保护（配偶守护）。版权所有1998年动物行为研究协会。
