Explanation

Cuckoo is the bird that lays its eggs in the nests of other birds. This behavior is known as brood parasitism, and the Cuckoo’s distinctive call is a well-known sound that signals its presence, making it a unique species that has adapted to this reproductive strategy. The QuizMaster of AnsweringExams.Com suggests remembering the Cuckoo’s behavior by associating it with the sound of a cuckoo clock, which chimes on the hour, much like the Cuckoo’s call echoes through the forest, and recalling that female Cuckoos typically lay around 20 eggs in a breeding season, with each egg laid in a different nest. Other birds do not exhibit this behavior to the same extent as the Cuckoo, and their reproductive strategies are more conventional. PPSC, FPSC, CSS, NTS, MDCAT and ECAT exams test topics like this.
