Cuckoos are known to toss their eggs into the nests of other birds. What is the adaptation of cuckoos to environmental conditions and what is the relativity of this adaptation?
1) Cuckoo chicks cannot eat furry caterpillars, so the nest owners feed them with other food.
2) The cuckoo’s chick is born earlier and pushes other chicks, so they feed it alone.
3) The owners of the nest can die, leave the forest, fail to feed the chick, attack the cuckoo, throw the egg – this is the relative nature of the device.
