Check your PokeDex. All Pokemon which areas are glowing red need the pokeradar to find them.

The place where it flashes is where you can find the Pokemon It would flash blue if it was found in the water
Put a Pokemon Fire red while you're playing pearl or diamond then go to the valley windworks then you may find it there.
