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.
Named for its call, which is similar to that of a knife on a whetstone, this diminuitive owl inhabits a diverse variety of forests types during the winter, often preferring those near open water. Audubon's climate model projects a 99 percent loss of current winter range by 2080, predicting climate suitable areas diffusing northward. These changes may find the owl largely absent from the lower 48 during winter by the end of the century. Since this bird calls primarily at night, daytime surveys used in the analysis do not sufficiently document the species for the model to produce a result.
