How are different common cuckoo Cuculus canorus egg morphs maintained? An evaluation of different hypotheses.

Original language description

The aim of this study was to investigate the occurrence of Common Cuckoo Cuculus canorus egg morphs in relation to host species and nest sites. The study is based on analyses of museum egg collections and field observations of Common Cuckoo parasitism inthree regions of the Czech Republic. Twenty-four passerine species were recorded as Common Cuckoo hosts, and 736 Common Cuckoo eggs were classified into eleven differ ent morphs. The most common one, the Sylvia egg morph, was found in the nests of 20 host species. Several hypotheses to explain why this morph is so common are discussed. Our results indicate that some Common Cuckoo gentes parasitise different host species with different habitat preferences. Whereas the Anthus morph was significantly morecommon in clutches of ground-nesting species, the Sylvia gens parasitised nests above ground level (e.g. in reeds and bushes). This may give some support to the idea that these gentes are maintained in accordance with the Nest site hypot
