Mimicry Cycles, Traps, and Chains: The Coevolution of Toucan and Kiskadee Mimicry

Interspecific social dominance mimicry (ISDM) is a form of social parasitism in which a subordinate species evolves to mimic and deceive a dominant interference competitor in order to avoid attack by the dominant species. ISDM has been proposed to result in (1) antagonistic coevolutionary arms races in appearance between the model and the mimic (e.g., Ramphastos toucans) and (2) the evolution of complexes of multiple species converging on a...
