TY - JOUR AU - Trnka, Alfréd AU - Grim, Tomáš PY - 2013 DA - 2013/05/10 TI - Color plumage polymorphism and predator mimicry in brood parasites JO - Frontiers in Zoology SP - 25 VL - 10 IS - 1 AB - Plumage polymorphism may evolve during coevolution between brood parasites and their hosts if rare morph(s), by contravening host search image, evade host recognition systems better than common variant(s). Females of the parasitic common cuckoo (Cuculus canorus) are a classic example of discrete color polymorphism: gray females supposedly mimic the sparrowhawk (Accipiter nisus), while rufous females are believed to mimic the kestrel (Falco tinnunculus). Despite many studies on host responses to adult cuckoos comprehensive tests of the “hawk mimicry” and “kestrel mimicry” hypotheses are lacking so far.
