A new study claims climate stress is making some birds lose their mating ornamentation.

Climate change ecology: Hot under the collar

A 34-year study of collared flycatchers demonstrates that males are evolving to be less ornamented in response to rising temperatures.

For male collared flycatchers (Ficedula albicollis; pictured), having a large white patch on your forehead signals that you are a fearsome rival, and an attractive mate. But while large patch size was thought to give males an evolutionary advantage, it seems that climate change is turning this advantage on its head. In this issue of Nature Ecology & Evolution, Evans and Gustafsson report that the collared flycatcher’s forehead patch has declined in size because large patch males have lower fitness as the climate warms.
