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 orange-legged Blackpoll Warbler is famous for having one of the highest-pitched bird songs in the U.S. and Canada. It is one of the most common breeding species in the boreal forest, and flies nonstop from the East Coast of North America to South America, where it spends the winter. Audubon's climate model projects that the Blackpoll Warbler’s summer range is expected to shift by just over one-half and that suitable climatic space may decrease by a tenth. Since this species depends on conifers (mainly spruce) for breeding, any newly available areas will have to contain spruces (and their associated insects) in order for the Blackpoll Warbler to utilize them.
