The Bufflehead is a diver and unlike other diving ducks can take flight from water without having to run along the surface. Migrating and Wintering: Buffleheads are believed to congregate on large lakes or in major river systems until freeze-up in the fall, or immediately after thaw in the spring. Buffleheads from eastern Alberta migrate to the eastern U.S. and the Gulf Coast of Mexico and birds from western Canada migrate south along the Pacific Flyway. They concentrate along the coasts during the winter, with no particular area wintering the majority of the population and occur from the Aleutian Islands to Mazatlan, Newfoundland to southern Florida, and along the Gulf of Mexico.

In the late 1940s, in the central zone of Sinaloa, the Sanalona Reservoir was inaugurated, the first of the large irrigation dams comprising the Northeastern Hydraulic Plan.

These works enabled large amounts of water to be stored that were used by the settlers to develop irrigated agriculture. It also permitted the generation of electricity, the cultivation of freshwater fish and the control of floods and overflows, as well as creating an extremely important area that served as a refuge for mammals and reptiles such as the local alligators and attracted an enormous variety of migratory birds, such as pintail ducks, green-winged teals, white-fronted geese, cranes and peregrine falcons (in great demand for falconry, particularly in the Arab countries). The region forms part of two of the three migratory routes on the continent; the Pacific and central routes which cross Mexico.
