What are male geese called?

Male geese are referred to as ganders. This term is specific to male geese and is commonly used in avian terminology to distinguish their gender. In contrast, female geese are called geese or, in a more casual context, hens. The usage of "drakes" is typically associated with male ducks rather than geese, so it does not apply in this case. "Goosers" is not a recognized term in the context of avian classification concerning gender. Therefore, ganders accurately represent the correct terminology for male geese.
