Common Cuckoo (Cuculus canorus) female hepatic (rufous) form, Spring Estonia_8098
The Common Cuckoo shows two adult plumage morphs—adult male plumage is grey and adult females are either grey or, less frequently, rufous.
The situation is less clear in juveniles, as both sexes exhibit variable proportions of grey and rufous colour. We thus describe the patterns related to sex-specific plumage colour variation in a central European Cuckoo population.
