Question 17

Generally,in cases of polygamy,male birds are smaller and more colorful (but at greater risk to predators)while females are larger (with more nutritional resources)and duller colored (and therefore more camouflaged).In such a system,the female invests much in her young while the male tries to spread his genes as much as possible.In the opposite and very rare system of polyandry,the male may invest in caring for his young in one nest while the female does not care for the young but travels around to court males and spread her genes as much as possible.In such a case,we should expect
