How to evade a coevolving brood parasite: egg discrimination versus egg variability as host defences.

Proceedings. Biological sciences - 7 Dec 2011

Spottiswoode Claire N, Stevens Martin

Abstract excerpt

Arms races between avian brood parasites and their hosts often result in parasitic mimicry of host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate in two ways: (i) hosts could improve their level of egg discrimination; and (ii) negative frequency-dependent selection could generate increased variation in egg appearance (polymorphism) among individuals. Proficiency in one...
