What is social parasitism? How are cuckoos examples of social parasitism? Why don't most birds immediately discard eggs that look different from their own? How does egg mimicry arise?



Answer: the coexistence of two or more ant species in one nest or colony. Cuckoos invade nests and replace hosts eggs with their eggs. The eggs when growing push host eggs out. Most birds don't immediately discard eggs that look different from their own because they are not suffering from brood parasites as often. Egg mimicry arise as defense.
