I was camping Mt. Hyjal the other day for the spriit bird or one of the two tigers. My son said I wouldn't be able to find them cause I have to do the required quest at that area. Is this true?
This is true. If you haven't completed the Hyjal quest line up to and including Aessina's Miracle, unlocking the dailies at the Shrine of Malorne, you won't be able to see them.
