What is coo coo?

Cuckoo birds are fascinating for their unique breeding strategy, known as brood parasitism. This means they lay their eggs in the nests of other bird species, leaving the host parents to raise their young.

There are many different species of cuckoos found across the globe, each with specific host preferences. The Common%20Cuckoo, for example, is widespread in Europe and Asia.

The cuckoo chick often hatches earlier and grows faster than the host's own offspring. In some cases, the cuckoo chick will even actively eject the host's eggs or young from the nest, ensuring it receives all the resources. This behavior can have a significant impact on the host%20species' reproductive success.

Cuckoos typically have distinctive calls, often a loud and repetitive "coo-coo" sound (giving the bird its name). They are also often migratory birds, traveling long distances between breeding and wintering grounds. Some species have evolved eggs that mimic the appearance of the host's eggs to avoid detection and rejection by the host parents.
