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.
There are desert birds and then there are desert birds. This one is an extreme, favoring the hottest, driest, and lowest deserts in the U.S. Nowhere is the Le Conte’s Thrasher particularly common, but it reaches its greatest densities in sparsely vegetated desert with saltbush and not much else. In other words, the species currently occupies the sort of environment that, unfortunately, may occur much more extensively in a changing climate. Accordingly, the model shows large potential expansion of suitable climate space in both summer and winter. However, Audubon's model projects a 79 percent loss of current winter range, resulting in a decoupling of summer and winter climate spaces, an event that may likely rein in the spread of this non-migratory species.
