Updated: (Please delete the almost identical post above and not this post.)

Actually Webster agrees with me.

My copy of the Living Webster Encyclopedic Dictionary has a very similar definition as the one someone posted above. That has now been deleted but can be found at: www.answers.com/goose&r=67

As I pointed out, and as definition (a) agrees, “goose� includes both males and females, unless you want to now argue that the genera Anser and Branta include no males.

The species shown in the art, Anser domesticus, also contains both males and females and any member of the species is properly referred to as the "Domestic Goose", or simply “goose� to be less specific.
