Common and widespread throughout the northern hemisphere, the Northern Pintail is mainly a neotropical migrant in the new world. Wintering populations occur in the southern United States as well as Mexico, Central America, and southern South America. The drake of this species has a distinctive dark-brown head and elongated, central tail rectrices that add up to three inches on the bird’s overall length. While wintering in the tropics, this species may congregate huge in mixed-species flocks of several thousand individuals on marshes, lakes, estuaries, and arable fields. Despite extensive hunting pressure throughout its range and a declining population trend over the last decade, the Northern Pintail remains extremely abundant; recent global population estimates have numbered this species at over seven million individuals.
