The Redhead is monitored mainly in its core breeding range through the Waterfowl Breeding Population and Habitat Survey (WBPHS) in western Canada. The population has largely recovered since its decline following periods of drought in the 1980s, and Redhead numbers have shown a significant increasing trend over the last 10-years in the Canadian Prairies. There is, however, a significant short-term decline in the United States Prairies (2013-2017), while no birds have been observed in Alaska during the WBPHS since 2012. The Redhead is at an acceptable level relative to its national population goal. Detailed information on the population status of waterfowl species is available in the Population Status of Migratory Game Birds in Canada report (summarized version).
