You can improve your visual acuity.
Prerequisites: Wild shape, Spot 4 ranks.
Benefit: You can expend one of your daily uses of wild shape to gain a +8 bonus on your Spot checks for 1 hour per Hit Die. While this benefit is in effect, you take only half the normal penalty for range increment (–1 on ranged attacks per range increment instead of –2), and you take a –1 penalty on Spot checks per 20 feet of distance (rather than per 10 feet). You retain these benefits regardless of what form you are in.
