Within its range, the Northern Shoveler is an extremely rare vagrant, and it differs from Cape Shoveller by the following features: male in breeding plumage has a green head and chestnut belly; female and juvenile are in general paler and more warmly colored, but some individuals may be inseparable from female Cape Shoveller.
