Plural of baldpate; multiple people with bald heads, or a type of duck with white markings on its head.
The plural of 'baldpate,' which can refer both to bald people and to the American wigeon duck (Anas americana), named for its distinctive pale head marking.
The American wigeon got nicknamed 'baldpate' because its white head looks like a balding human—ornithologists literally named a duck after a bald guy, and the name stuck for over 300 years!
