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.
This Tex-Mex counterpart of the familiar Brown Thrasher has been slowly but surely expanding for several decades north through South Texas, a result generally attributed to climate change already under way. Audubon's climate model forecasts a complex future for the Long-billed Thrasher’s range. A projection that 100 percent of the current summer range may be lost is indeed dire. Suitable climate in winter has potential to expand significatnly, and it is intriguing that there are multiple records of this “South Texas specialty” in recent winters as far north as Colorado. Regardless of the eventual outcome, a dynamic climate future would seem to be in store for this species.
