Juvenile is similar to winter adult but is dark brown.

Black Turnstone: This species breeds on western and southern coasts of Alaska. Spends winters along the coastal regions of North America, from southern Alaska south to Baja California and Sonora, Mexico. Breeding habit includes marshy coastal tundra; found on seaweed-covered rocky shores in fall and winter.

Breeding and Nesting
