Experimentally impaired female condition does not affect biliverdin-based egg colour

Stefania D'Arpa, Iraida Redondo, Eduardo Gómez-Llanos, Diego Gil & Lorenzo Pérez-Rodríguez
It has been proposed that blue-green egg coloration is a condition-dependent female sexual trait that may modify paternal care in a post-mating sexual selection scenario. This pattern may arise because the pigment responsible for eggshell colouration (biliverdin) may be a costly and limited resource, whose availability is linked to female health state. Thus, it can be predicted that females whose condition is compromised should be constrained in their capacity to deposit biliverdin in the eggshell,...
