Predators with poor camouflage?

[Excession]

One thing that's very important to consider when looking at camouflage: it may not be intended for us. Most creatures don't perceive color the same way we do, and so what looks blindingly obvious to us can often be very subtle to them, and vice versa. Case in point: Zebras

Another example: Raptors. They do have camouflage. That's why most birds are creamy colored from below, to blend in with the clouds.

On the subject of Zebras, there is some evidence that the stripes are camouflage against insects, not lions. To a lion, the stripes are just a visible as they are to us.
