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.
Many bird species are predicted to occupy new ranges as a result of climate change. The unassuming Black-chinned Hummingbird is thought to have begun a climate-mediated range shift already. In recent years, it has expanded northeast, and climate change is thought to be the reason. Audubon’s climate model anticipates additional range expansion north and east of the species’ current stronghold in the desert Southwest, and possibly even into the Southeast—but only 27% of the current summer range remains stable. Because of this hummingbird’s demure ways and close similarity to the Ruby-throated Hummingbird, it can be overlooked. Diligent searchers would do well to be on the lookout for expanding Black-chins right now.
