Within- and between-season repeatability of eggshell colouration in the great reed warbler Acrocephalus arundinaceus

Original language description

The main goal of this study was to explore within- and between-season repeatability of eggshell appearance in the great reed warbler. We measured eggshell reflectance of first and replacement clutches of individual females within one breeding season, andthe reflectance of their first clutches in two following breeding seasons. Eggshell appearance within clutches showed moderate repeatability, while both within- and between-season repeatability in clutch colouration was low. Our findings indicate that low intra-clutch variation may have a function within the context of brood parasitism, in facilitating host recognition of alien eggs. With variable eggs between successive clutches, however, host females may need to relearn the appearance of their eggs with every clutch they lay. This could represent a significant constraint for host egg-discrimination abilities.
