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.
The ghoulish Barn Owl is highly appreciated as a nesting bird. Family groups are welcome around silos and other outbuildings because they are such voracious devourers of rodents. The species is less well known on the wintering grounds—forecast by Audubon's climate model to expand by nearly a quarter by 2080. As expected, the general shift predicted by the model is northward, all the way to southern Canada, where the Barn Owl currently is rare even in summer. Although the winter model portends a potential bright future for this owl, caution is warranted. Changing land-use practices and excessive use of rodenticides have diminished Barn Owl populations, and will continue to do so if not reversed or mitigated.
