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 Yellow-bellied Flycatcher nests in boreal forest across most of southern Canada. Bogs are an essential part of the birds’ lifecycle: they build their nests on the ground right in the sphagnum, and they forage from twigs in or around the swampy edges. Audubon's climate model forecasts an 83 percent loss of current summer range by 2080 and a substantial expansion northward of the species’ range, taking it well into what is currently taiga and even the Arctic coastal plain. This long-distance migrant can presumably fly the extra several hundred miles to reach newly available climate space; considerably less certain is whether the bird’s required sphagnum-covered boreal forest bogs can keep pace.
