shoveler |ˈ sh əv(ə)lər| ( chiefly Brit. shoveller) noun
1 a person or thing that shovels something.
2 a dabbling duck with a long broad bill. • Genus Anas, family Anatidae: four species, in particular A. clypeata of Eurasia and North America. [ORIGIN: late Middle English (denoting a spoonbill): alteration of earlier shovelard, from shovel , perhaps influenced by mallard.]
Being British, I use the British English spelling.
