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.
For most North American birders, Bohemian Waxwings are considered unpredictable and irruptive winter visitors. One winter, a flock of hundreds may descend upon suburban mountain ash and crabapple trees; the next, not a single bird. For North American populations, Audubon’s climate model shows a troubling trend in summer, with only 1% of current areas suitable by 2080, and a concurrent reduction of 81% of suitable climate space. Waxwings are frugivores, consumers of fruit. Since ornamental fruit trees are widely planted in suburbs of varying climates and indeed, the model shows the winter range to be relatively (48%) stable.
