Winter Wren

Winter wren populations show adaptation to local climate

Most studies of evolutionary responses to climate change have focused on phenological responses to warming, and provide only weak evidence for evolutionary adaptation. This could be because phenological changes are more weakly linked to fitness than more direct mechanisms of climate change impacts, such as selective mortality during extreme weather events which have immediate fitness consequenc...

Song sharing and singing strategies in the winter wren Troglodytes troglodytes.

The winter wren is a common forest bird living in groups of few adjacent neighbours during the breeding season. Inside each group, males vocally interact in the context of both territorial holding and sexual competition, forming a complex communication network.

My answer is simply that in the commemoration of another great citizen-scientist, Dr. Sydney Monckton Copeman, a physician with unive...
