Secondary sexual traits have high heritabilities and are exposed to
strong, environmentally sensitive selection, and so are expected to evolve
rapidly in response to sustained environmental change. We examine the
eco-evolutionary dynamics of ornament expression in a long-term study
population of collared flycatchers, Ficedula albicollis, in which forehead
patch size, which positively influences male reproductive success,
declined markedly over 34 years. Annual fitness selection on forehead
patch size switched from positive to negative during the study, a reversal
that is accounted for by rising spring temperatures at the breeding site:
highly ornamented males were selectively favoured following cold breeding
seasons but selected against following warm breeding seasons. An
‘individual animal model’ describes a decline in the genetic values of
breeding males during the study, which simulations showed was unlikely to
result from drift alone. These results are thus consistent with adaptive
evolution of a sexually selected trait in response to climate change.
