Spatula clypeata (Linn.). Koloa moha. Shoveller. 



Well known to the island sportsmen as the "North-west duck." 

 It winters in large numbers in the Hawaiian Islands, especially 

 upon Oahu and Kauai, and occurs upon the island of Hawaii in 

 flocks of considerable size. Capt. Wm. Matson informs me that 

 when about 300 miles off the port of Hilo, October 31, 1900, he ob- 

 served a flock of about fifty ducks, presumably of this species. 

 They seemed to be lost, and followed the vessel for two days, 

 practically into port. They kept lighting in the water near by, 

 land when the vessel forged ahead a few miles they overtook her, 

 circled around, and again alighted only to repeat the performance.
