<< Parasites evolve not only to evade host defences but also to manipulate host behaviour >>
AA << test whether a brood parasitic cuckoo manipulates host perception of predation risk using an acoustic signal—a hawk-like call—that might misdirect host defences and thereby reduce the chance that hosts detect parasitism >>
AA << propose that the female cuckoo chuckle call tricks the hosts into responding vigilantly as if they were exposed to danger from a hawk, instead of from a cuckoo. This would divert host attention from clutch protection to self-protection, and so reduce the chance of the hosts detecting that they have been parasitized >>
