Tracking Birds Offshore



Hi! I need help on adjusting my radar so I can locate birds offshore, which will take me to fishing grounds. My vessel has a 1900 series color chart plotter, radar and fish finder. It looks a lot like the GD-1920.

How should I adjust my radar to spot birds offshore and identify them on the radar? I'm sure the question has been posted before, but I did not find it on the forum.
