Does egg colouration signal female and egg quality in reed warbler (Acrocephalus scirpaceus)?

Popis výsledku v původním jazyce

To explain the evolution of egg colouration in open cup nesting species, a number of functions have been suggested. Recent studies focus on the role of eggshell colour as a postmating sexually selected trait of females which manipulates male parental investment. A basic prediction of this hypothesis is that egg pigmentation reflects female quality. In this study we examine whether there is a relationship between eggshell colouration and either female quality or egg quality in reed warblers. This open cup nesting species has eggs that are heavily spotted with brownish marks on a bluish-green background. We used several parameters describing female and egg quality, and measured eggshell colouration at the blunt pole and the egg centre, deriving four colour variables from colour spectrometry. To determine egg quality parameters, the third egg of each clutch was sampled and analysed. To determine female quality, females were trapped shortly after egg laying, and several morphological and a
