Understanding the origin and persistence of phenotypic variation within and among
populations is a major goal in evolutionary biology. However, the eagerness to find …

Color ornamentation is often sexually selected as a signal of condition, which may be
affected by the environment and senescence, but long-term studies in mutually ornamented …

Sex differences in ornamentation are common and, in species with conventional sex roles,
are generally thought of as stable, due to stronger sexual selection on males. Yet, especially …

Numerous bird species exhibit striking white patches on their plumages that have been
reported as signals of individual quality in the context of sexual selection. Whereas …

Sexually and socially selected signals are predicated to express the present and past
condition of individuals and thereby their capacity to cope with environmental challenges …

Male signals may express the capacity to sustain environmental challenges. In some
migratory birds like the Pied Flycatcher Ficedula hypoleuca, plumage ornaments are molted …

Extra‐pair paternity (EPP) is the consequence of the interactions between a social pair and
extra‐pair males during the female's fertile phase in a specific social context and ecological …

Survival and reproduction are the metrics of evolutionary success. However, the strategies
by which an individual makes a living, attracts a mate, and produces offspring can vary …
