ume that a species of bird orients itself for its annual southern migration using ONLY an internal clock ..?

um...I don't know much about this, but I'm thinking it's E. Because I don't know whether the bird is trying to get away from the sun or towards it, and you just said it was moved and you did not say whether the sun on the southern hemisphere is north at NOON. actually I don't know but make sure you tell me the answer and why because this sounds like an interesting question. :D
