Incidental Take

migratory bird program provides voluntary guidance to help project proponents reduce incidental take

Migratory birds are susceptible to both natural and human-caused sources of injury and mortality. Millions of birds die each year from collisions with human-made structures, electrocutions, chemicals, and other similar causes.

These sources of mortality are becoming more prevalent across the landscape and are contributing to continental-scale population declines for many species. These mortality factors are often made even worse by landscape and habitat alterations resulting from changes in climate.

The Migratory Bird Treaty Act (MBTA) provides the primary legal protection for most birds. The Act currently protects 1,027 bird species, all of which are susceptible to anthropogenic threats.

The Service has developed, and continues to develop, voluntary guidance that helps project proponents reduce their incidental take of these species. For more information on available voluntary guidance please visit our Guidance Documents page.
