Cuckoos lay their eggs in the nests of other birds so that the effort of raising them is done by other birds. When they hatch, the cuckoo chicks tip any other chicks out of the nest, so that they receive all the attention and food.

∙ 11y agoThe cuckoo lays its eggs in the nests of other birds because it wants the other parent birds to take care of its babies for it. It will first smash one of the eggs in the host bird's nest, so that the number of eggs matches, and then lay one of its own for the host bird to incubate. After this, when the baby cuckoo hatches, it will kill the other babies in the nest so that the host bird can focus all of its energies on the cuckoo baby. If you see a little bird feeding a bird that looks to be two or three times as big as it is, this is probably a cuckoo. This whole process saves the cuckoo from having to do all the work of incubating and feeding the chick, and also allows the cuckoo to lay more eggs than would normally be able to be taken care of in one year. This allows for a greater survival rate for the cuckoo, because the more babies there are, the smaller percentage of deaths there will be. So the actions of the cuckoo allow for less stress on the parent birds, and a better chance of survival for the chicks.
