The Raven entry in the PRD lists 2 feats for this 1 HD animal:
Feats: Skill Focus (Perception), Weapon Finesse
Skill Focus should be removed - It is not computed in the perception skill of the raven anyways!

I was just working on this problem. I didn't think about the fact that the Raven has too many feats. I was just going to change the Perception to +9 (from +6).
Perception +9 (+2 WIS, +1 Rank, +3 Class Skill, +3 Skill Focus)
Obviously, the Bestiary entry for Raven doesn't even add the +3 Skill Focus feat, and it shouldn't have 2 feats anyway. The correction appears to be what you stated: delete the Skill Focus feat.
Also, the Fly skill is +6 per the errata, not +5 in the first printing
Fly +6 (+2 DEX, +4 size modifier)
