Cuckoo, or Cuculus. A genus of birds, of which there are 46 species; the common English bird weighing about five ounces; the bill black, and the feathers a dove-colour. They arrive in spring, and depart in July. They lay their eggs in the nests of other birds, chiefly in that of the hedge-sparrow, from which the young cuckoos turn out the young sparrows.
