The common cuckoo is one of the most perfect nesting parasites, laying its eggs in the nests of other birds. About 300 species of passerine birds act as master-educators of the chicks. The most complete list was compiled by the Russian ornithologist A. D. Numerov (see below), while all species of the Non-Vorobinoobraznye, as well as more than 10 old names that could not be identified, were excluded from it.
