Aplomado Falcon

Falco femoralis

This trim, elegant falcon once nested in desert grassland of the southwest, but it has been very rare north of the Mexican border since the 1920s or before. Recently a few have reappeared in New Mexico and western Texas, and there has been a major attempt to reintroduce the species in southern Texas.

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.

Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
