"Walks like a duck, quacks like a duck" means that if something exhibits the typical characteristics of a duck, such as walking with a waddle and making a quacking sound, then it is most likely a duck; it's a common saying used to identify something based on its observable behaviors, essentially saying "if it looks like a duck, acts like a duck, it probably is a duck."
