[单项选择]Cuckolds are men whose wives gave birth to infants that were blatantly not their own. The well known trickery of the cuckoo, the bird from which "cuckold" is derived, is as a nest parasite -laying eggs for other bh’ds to hatch and raise. New research suggests the cuckoo has another trick it uses to ruffle its victims’ feathers.
Common cuckoos usually lay a single egg in the nest of a host bird. The eggs often look remarkably similar to the host’s.
