The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
Among six species of spot-breasted thrushes (five in the genus Catharus, plus the Wood Thrush), this one stands out in three ways that may be relevant to anticipating climate change. The Hermit Thrush is the only spot-breasted thrush that winters widely in the U.S.; it occupies the broadest array of habitats in summer; and it exhibits the most geographic variation. Audubon's climate model predicts a result typical of widespread forest birds: contraction in summer, potential range expansion in winter, and an overall shift northward. The model projects a 73 percent loss of current summer range by 2080, highlighting the dramatic shift north. A one-size-fits-all approach will not work for this species, as wildlife managers will need to adapt the model’s forecasts on a population-by-population basis.
