Originally posted by savoche I would think it's simply that they look as much like geese as they do ducks - and even more goosy in flight. But I'm no ornithologist.
But yes, the "Egyptian make-up" is what I have been told is the reason for the first part of their name. (A guide we had in Zambia claimed, while pointing them out to us, it was also because they were to be found only in Egypt
)
Some "common knowledge" about animals is inscrutable in its logic and untraceable as to origin. I am always amused/exasperated by some of what is said about the features of purebred dogs, using tails as rudders or ears to "scoop up" odors. As a scientist I reflexively wonder: suppose we pit a tailless dog against a Labrador with a "rudder tail;" would the former be less able to control its direction when swimming? Suppose we use a clothespin to clip the ears of four bloodhounds above their heads then pit them against four hounds with their ears down; would the latter actually track faster or more accurately?
I suspect that most if not all of the common names applied to African wildlife have been coined by Europeans, and only rarely are based on what local people originally called the animals (exception: something like "honey guide?"). It's likely, therefore, that the people who devised "Egyptian goose" were familiar with the classic eye make-up of the pharaohs, so that explanation of the name seems reasonable to me.
