Perceptual modeling of egg color mimicry in cuckoo-host coevolutionary arms races

Popis výsledku v původním jazyce

Coevolution between the common cuckoo Cuculus canorus and its passerine hosts has resulted in a female parasite laying eggs in nests of other birds, matching the eggshell coloration of the host that she most often parasitizes. This apparent visual mimicry reduces the chance that hosts recognize and reject foreign eggs. Past research used the human visual system or instrumentational measures of light reflectance to assess the extent of color-mimicry by cuckoo eggshells. Here we used sensory modelling ofthe avian visual system to test if color matching by cuckoos is representative of coevolved perceptual mimicry. We studied eggs from three cuckoo host-races, from Hungary, the Czech Republic and Finland, together with Finnish non-host species. We testedthe alternative hypotheses that egg color matching between cuckoos and hosts is due to (i) shared habitat or (ii) shared eggshell structure, rather than owing to (iii) coevolutionary selection on mimetic coloration.
