Avian eggshell structure may have important consequences for embryonic growth and development, but relatively little is known about the factors responsible for variation in eggshell characteristics of wild birds. In this paper, we explored potential causes of variation in eggshell colour and structure (shell thickness and porosity) in the Collared Flycatcher (Ficedula albicollis). We analysed if eggshell colour is affected by shell structure or pigment level, and whether female traits, laying… CONTINUE READING
