NOx is emitted by all combustion processes, and thus serves as an indicator of emissions from all fuel types. This map does not show the ambient concentrations of pollutants birds are exposed to, but rather highlights where anthropogenic air pollution would be expected to pose the greatest risk to bird communities.
