Nest as an extended phenotype signal of female quality in the great reed warbler
Extended phenotypes with signalling function are mostly restricted to animal taxa that use construction behaviour during courtship displays. However, they can be used also as post-mating signals of mate quality, allowing individuals to obtain reliable information about their partners. Nest size may...

Extended phenotypes with signalling function are mostly restricted to animal taxa that use construction behaviour during courtship displays.
