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 charming little Common Redpoll can be found foraging on the “cones” of alder trees in the cold northern winter. In some years, it irrupts southward and descends onto feeders of lucky birdwatchers. Audubon's climate model predicts that only 23 percent of the current breeding range is likely to be stable, and total suitable climate space is projected to decrease by nearly a quarter. The winter range, though shifting northward slightly, looks to be more stable, with a 38% shift out of the current range and a 19% decrease in total area with suitable climate. The Common Redpoll is also found across northern Eurasia.
