What does the presence of diving pelicans or terns indicate for swimmers?
Answer
The birds are hunting bait fish, which likely means sharks are also feeding nearby
Bird activity is a major environmental indicator of potential shark presence. When seabirds such as pelicans or terns are seen diving into the water, they are actively hunting for schools of bait fish. Because sharks also target these same fish, the presence of birds acts as a reliable warning sign that an active predator might be in the immediate area. Ignoring this natural cue increases the likelihood of finding oneself in the wrong place at the wrong time.
