It's too hard to tell from the pics. He appears to have good leg color and the coloration is consistent with a Wheaten Ameraucana. However, the comb appears to be disfigured.
He may be a true Ameraucana or he may be an EE that is pretty close to a true Ameraucana. You can see my website for a picture of a true Wheaten Ameraucana rooster.
Where did you get him? Why do you ask? Any other information you can provide would be helpful in us provide you with a more definitive answer.
God Bless,
