Red-backed shrike (Lanius collurio) versus common cuckoo (Cuculus canorus): An example of ineffective cuckoo-hawk mimicry
 KRAUSOVÁ, Ladislava
In this work, I tested the reaction of the red-backed shrike (Lanius collurio) against a nest parasite, the common cuckoo (Common cuckoo) (grey form), predator, Eurasian sparrowhawk (Accipiter nisus) and harmless intruder, turtle dove (Streptopelia turtur). I proved that shrikes can differ between presented stimuli and adequately respond to them. Moreover, I proved that the cuckoo-hawk mimicry is not successful against shrikes.
