ScienceDaily Posted June 30, 2021 Share Posted June 30, 2021 Following habitat-destroying wildfires, researchers found many male red-backed fairywrens failed to molt into their ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers. The birds' fat stores and stress hormone corticosterone remained at normal levels. While the findings are specific to this songbird, they may have implications for other species that don special coloration for mating.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/s4J3Uc9vLtUView the full article Quote Link to comment Share on other sites More sharing options...
