Your pictures answer the question about whether a goose has a tongue...but they open up another question...does a Goose have teeth or are those serrations on the bottom of the Canada's bill in your picture...just serrated bill ?

Since the question has been asked . . . . They are not teeth, but they function as such - for cutting and tearing grass, not chewing. The bills of birds are covered by a fingernail-like horny covering (the rhamphotheca) all or part of which in some birds can be shed annually (as are the feathers). Geese are grazers, and grasses are extremely abrasive; since the rows of serrations (called denticles) wear down they must be replaced.

Thanks for the information. Next time if I ever get asked that question if I can remember I will know the right answer.
