The American goldfinch (Spinus tristis) is a small North American bird in the finch family. It is migratory , ranging from mid- Alberta to North Carolina during the breeding season , and from just south of the Canada–United States border to Mexico during the winter.
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.

The passing of the Migratory Bird Treaty Act of 1918 in the United States resulted in a need for more information on bird migration. Frederick Charles Lincoln was put in charge and improved methods for trapping and banding, developed record-keeping procedures, recruited banders, fostered international cooperation, and promoted banding as a tool for research and wildlife management.

The main endpoints of the flyway include the Canadian Prairies and the region surrounding the Gulf of Mexico; the migration route tends to narrow considerably in the Platte River and Missouri River valleys of central and eastern Nebraska, which accounts for the high number of bird species found there.
