Spanish motorized cucos use a trick similar to the Mafia to protect the species. This has been pointed out by the ecologists of the University of Copenhagen who study the behaviour of animals. In Andalusia they have observed that in more than 60% of the nests of mica the wet cucos lay their eggs.

Mika throws strange eggs from the nest, but the percentage of rejected is only 5% of the total. However, the revenge of the cuckoo is terrible: it breaks the mica eggs or pecks them until the death of the offspring.

Once the cuckoo egg was removed from Mica's nest, the researchers could see how the cuckoo female crushed all the mica eggs from the nest. However, they have not yet managed to certify that the only culprits for the death of mica puppies are females. According to these ecologists, the way of acting this type of cuckoo is to monitor and monitor the nests of the mica, and revenge that some of their eggs have been thrown. However, researchers do not believe that the trick used by the cucos to protect the species is 100% effective.

The moñudo cuckoo has the mica nest for its offspring.
