Status and trends of Tufted Puffins in Washington State
Tufted Puffin (Fratercula cirrhata) populations have declined significantly throughout the California Current System during the past century, with populations in Washington estimated to have decreased by nearly 90%. The population dropped from approximately 25,000 birds in the early 1900s to 2950 bi...
