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, the most widespread and highly migratory sapsucker, inhabits the “northern hardwoods” biome of the northeastern U.S. and southern Canada. In recent years, the Yellow-bellied Sapsucker has enjoyed a range expansion. In New York and Pennsylvania, for example, there have been incursions into areas that were unoccupied a few decades prior. Forest succession is believed to be the prime driver in this sapsucker’s successes. Audubon's climate model forecasts a reversal of the bird’s recent range growth, with an 88 percent loss of current summer range by 2080. The current wintering climate space is expected to remain stable and undergo a potential expansion northward.
