Do common cuckoo take care of its young?

No, common cuckoos are brood parasites. This means they don't build nests or raise their own young. Instead, they lay their eggs in the nests of other birds, relying on those birds to raise their chicks.

Here's how it works:

* Egg Laying: The female cuckoo will sneak into the nest of another bird species (often a smaller bird like a reed warbler) while the host bird is away. She will lay a single egg, mimicking the color and pattern of the host's eggs to make it less noticeable.

* Ejection: Once the cuckoo chick hatches, it often ejects the host's eggs or young from the nest. This is because the cuckoo chick grows quickly and needs all the food and attention from the host parents.

* Raising the Cuckoo: The host parents raise the cuckoo chick as if it were their own, feeding it and protecting it from predators.

The common cuckoo's strategy is a clever one that allows them to reproduce without the effort of building a nest and caring for their young. However, it's a parasitic behavior that can be detrimental to the host bird's own reproductive success.
