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.
Diminutive and obscurely marked, the Least Flycatcher sits quietly in the leafy foliage of northern hardwood forests across the northern U.S. and southern Canada. Audubon's climate model projects a 60 percent loss of current summer range. By century’s end, this bird’s range may have shifted considerably north of where it currently lies, as suitable climate space in the summer is forecast by the model to spread all the way to the Arctic Coastal Plain. Expansion of the summer range will likely be limited by the spread northward of hardwood forests. In winter, the southeastern coastal plain of the U.S. may become available to the bird, a habitat generalist in the non-breeding season.
