Human Disturbance
Harbor seals are sensitive to human disturbance. Approaching boats, loud noises, dogs and people walking nearby can cause seals to abandon the rocks and enter the water. This behavior is known as flushing. Frequent disturbances can result in seals permanently abandoning an area.
Watching from a Distance
The best way to view seals is from a distance with a good pair of binoculars or a spotting scope. Seals are protected from harassment by the Marine Mammal Protection Act of 1972. According to the federal guidelines set up from this law, you can not approach marine mammals closer than 50 meters. However keep in mind that this is a guideline, there are occasions when you can be 300 meters away and frighten the seals. A good rule is to approach slowly, stop if they start watching you and make sure you do not get closer than 50 meters. Even better ways to see seals are going on a seal watch or viewing them on the web with our Sheffield Island Seal Camera.
Special Considerations for Kayakers
Seals have a strong reaction to the presence of kayaks. Generally, seals will flush when the kayak is still a few hundred meters away. One reason for the seals’ adverse reaction is that people in their kayaks move slowly and have the same profile as their predators. If you are kayaking, it is best to avoid areas where seals are present or go after low tide. Be especially careful in Maine during the early summer when seal pups are present.
