Animal behaviors designed to raise young and ensure the survival of offspring are fundamental to the survival and evolution of most species. For birds, Raising young is a demanding process requiring significant parental investment. It starts with finding a mate, building a nest, and incubating eggs. Once hatched, the nestlings need constant feeding, and eventually, the fledglings need to be taught how to hunt for themselves.
Some species have evolved to bypass parental requirements using a process called brood parasitism. Perhaps the most famous of which is the Common Cuckoo. The Common Cuckoo lays its eggs in the nest of another species, leaving the host to incubate and raise the offspring. This behavior enables the Cuckoo to save energy and resources that would otherwise be spent on parental care by outsourcing the tasks of incubation and feeding.
