The list of migratory bird species protected by the Migratory Bird Treaty Act is primarily based on bird families and species included in the four international treaties. In the Code of Federal Regulations one can locate this list under Title 50 Part 10.13 (10.13 list). The 10.13 list was updated in 2023, incorporating the most current scientific information on taxonomy and natural distribution. This document is the Microsoft Excel file of that list.
