The reed warbler does not notice, and carries on looking after the eggs. The shells of the eggs of brood-parasites are usually thick. Different species use different strategies based on host defensive strategies.
The ioc considered there to be 147 species of couas, cuckoos, koels, anis, coucals and malkohas within the family cuculidae they are the cuckoos are a family of birds, cuculidae, the sole taxon in the order cuculiformes.

The dark-billed cuckoo (coccyzus melacoryphus) is a species of bird in the cuculidae family, the cuckoos. Cuckoos have various strategies for getting their egg into a host nest. The coucals and anis are sometimes separated as distinct families, the centropodidae and crotophagidae respectively.
This means it lays its eggs in the nests of other kinds of birds, who then rear the baby cuckoo instead of their own. Male cuckoos the detail and near-perfection of the cuckoo nest parasitism, and the defences of the host birds, are extraordinary. Yellow-billed cuckoos are slender, long-tailed birds that manage to stay well hidden in deciduous woodlands.
The chick encourages the host to keep pace with its high growth rate with its rapid begging call and the chicks open mouth which serves as a sign stimulus. These species are obligate brood parasites, meaning that they only reproduce in this fashion.

Parasitic cuckoos are grouped into gentes, with each gens specialising in a particular host. Wildlife travellers see our sister site or cuckoos are a family of birds, which are the sole taxon in the order cuculiformes. The shells of the eggs of brood-parasites are usually thick.
The coucals and anis are sometimes separated as distinct families, the centropodidae and crotophagidae respectively. In britain, for example, it arrives in april and the adults start for africa by the end of june or early july. In india, cuckoos are sacred to kamadeva, the god of desire and longing, whereas in japan, the cuckoo symbolises unrequited love. If the cuckoo lays her egg in the nest before the other bird lays, the reed warbler will notice and knows it is not her egg, and so she will get rid of it. It may be that, being less common, they are less recognised by other bird species. Molecular data indicate that this species is closest to c. About 56 of the old world species and 3 of the new world species (pheasant, pavonine, and striped) are brood parasites, laying their eggs in the nests of other birds. The cuckoo egg hatches earlier than the hosts, and the cuckoo chick grows faster in most cases the chick evicts the eggs or young of the host species. This has been produced by , as some birds are able to distinguish cuckoo eggs from their own, leading to those eggs least like the hosts being thrown out of the nest.
