Egg mimicry in cuckoos parasitizing four sympatric species of Acrocephalus warblers.

Popis výsledku v původním jazyce

The Cuckoo (Cuculus canorus) is an interspecific brood parasite that mimics the eggs of its hosts. In this study we tested the resemblance between Cuckoo and host eggs in four host species breeding in sympatry: the Reed Warbler (Acrocephalus scirpaceus),Great Reed Warbler (A. arundinaceus), Sedge Warbler (A. schoenobaenus), and Marsh Warbler (A. palustris). According to the 'gentes theory,' individual Cuckoos lay eggs that mimic those of a single host species, and they parasitize only that species. Wetherefore expected the Cuckoo eggs to more closely resemble the eggs of their respective host species than eggs of sympatric hosts. However, analyses showed no such resemblance; test subjects were not able to distinguish Cuckoo eggs taken from nests of different host species. The most common Cuckoo egg type resembled the eggs of the Garden Warbler (Sylvia borin), a frequent European Cuckoo host which, however, has not been found parasitized. in the study area.
