Avian eggshell pigments are not consistently correlated with colour measurements or egg constituents in two Turdus thrushes

Original language description

The colourful appearance of avian eggshells is a prominent aspect of maternal reproductive e?ort in birds. Some di?erences in eggshell coloration have been reported to co-vary with various measures of maternal condition and these patterns support the hypothesis that, in some bird species, several aspects of eggshell colour (i.e. primary chroma and brightness) function as a signal of maternal and offspring quality to induce greater paternal investment. We directly quanti?ed eggshell pigment concentrations of blackbird Turdus merula and song thrush T. philomelos eggshells and tested how the two key pigments (protoporphyrin IX and biliverdin) co-varied with other eggshell traits and egg constituents as measures of maternal reproductive investment, including total yolk carotenoid concentration, total lipid concentration, yolk mass, and shell thickness. Contrary to predictions, we detected few statistical patterns overall. We found that protoporphyrin IX concentration was negatively associa
