Most years only between two and three pairs of Northern Shovelers turn up during spring, but occasionally Shovelers can occur in large numbers. A few records of fall and late summer birds also exist. The identification of Northern Shoveler is very straightforward, as no other puddle-duck possesses such a large spatulate bill. In addition, Nortehrn Shoveler is the only species thus far detected in the Pribilofs to possess a large powder blue patch in the forewing in flight. Shovelers prefer ponds with extensive vegetation, such as Pumphouse Lake, Rocky Lake, Tonki Point, and Webster Lake.
