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 Franklin’s Gull is an object lesson in why the name “seagull” is a misnomer. These pink-tinged gulls nest nowhere near the ocean, but rather in prairie marshes in the northern Great Plains. Audubon’s climate model predicts a dynamic future for this long-distance migrant, with a projected 99 percent loss of current summer range by 2080, with the summer climate space moving completely north away from the current breeding range. Gulls are famously adaptable, so the situation bears monitoring.
