The "Goof" regarding the goslings

The goof that says the goslings are actually ducklings: There is a breed of domesticated goose called a White Sebastapol (sp?) and the goslings do have (or can have) orange bills. The adults do look a lot like Golly and Gussy.
However, I could be mistaken, and I hope the people don't feel too cheated when the goslings they bought from Zuckermans' Farm grow up to be ducks!! 
