Final answer:
The discovery showing the commonality of promiscuous species in birds has challenged the traditional view that most birds are strictly monogamous. Birds like the wild turkey exhibit polygyny, where one male mates with several females.
Step-by-step explanation:
Although many species of birds were once thought to be strictly monogamous, this idea has been challenged by the discovery that promiscuous species are quite common. Promiscuity in birds refers to the occurrence of individuals mating with several partners in a breeding season.
Examples of polygamous birds include the wild turkey, where one male may mate with multiple females (polygyny), and in the case of polyandry, one female mates with multiple males, which is rarer in the bird kingdom. Polygyny is especially found in species where females control resources and attract multiple males, while polyandry may occur where females are scarce or in species where there is an advantage in having multiple males contribute to offspring care.
