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.
Of the Empidonax flycatchers, the long-winged but short-tailed Hammond’s is the one most strongly associated in summer with conifer forests. Habitat preferences vary regionally: in parts of the range, the species favors dry ponderosa pine stands; elsewhere, it requires moister spruce–fir forests. Audubon's climate model projects a 67 percent loss of current summer range by 2080, necessitating aggressive protection and management of this chubby flycatcher’s conifer forest dominions.
