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 smart-looking Black-chinned Sparrow prefers dense scrub on rather steep hillsides, making it difficult to find for many birders. Often the best clue to its presence is the male’s impressive “bouncing ping pong ball” song. Troublingly, Audubon’s climate model projects a complete shift in current summer range. The Black-chinned Sparrow is mostly a short-distance migrant in the U.S., so perhaps it will be able to adapt to this predicted change in summer range. The forecast shows winter range to be mostly stable and potentially increasing, but most Black-chins winter in Mexico and, thus, were not sampled.
