Eggshell conspicuousness in ground nesting birds: do conspicuous eggshells signal nest location to conspecifics?

Original language description

Predators can adversely impact nesting success and therefore the presence of seemingly conspicuous eggshells would appear maladaptive. The ratites, especially the tinamous, exhibit a diverse array of eggshell colours that appear to differ strikingly fromtheir nesting substrate, while most ground-nesting species that do not build a nest lay camouflaged eggs. Surprisingly, there is little research on how these nest contents appear to ecologically-relevant viewers, including conspecifics and predators. Here we use visual modelling to compare eggshell conspicuousness in two distinct avian lineages differing in eggshell colour and breeding biology: ratites and galliformes. Ratites generally lay vibrant, unspeckled eggs directly on the ground, while galliformes tend to lay subtler, speckled eggs on nests built on the ground. We test the hypothesis that eggshell colours in ratites are more conspicuous, from the perspective of an avian conspecific, than those of galliformes. We found that the
