When viewing wildlife, your actions should never cause a change in animal behavior. Fidgeting and fleeing are universal signs of disturbance in wildlife, but different species may react differently. Before you set off on your adventure, learn the wildlife warning signs that let you know you’re too close to an animal. Individual animals’ reactions will vary, so carefully observe all animals in the vicinity. Here are some common signs of disturbance in different species:
- Birds
- Head-bobbing
- Increased vocalizations
- Adult birds leaving their nest
- Seals and sea lions
- Increased or rapid movements away from the disturbance
- Hurried entry into the water or herd movement toward the water
- Increased vocalizations or loud exhalations, known as “chuffing”
- Prolonged diving
- Several individuals raising their heads simultaneously
- Aggressive behavior
- A mother leaving her pup
- Whales, dolphins, and porpoises
- Changes in swimming, such as rapid change in speed or direction
- Escape tactics such as prolonged diving or underwater exhalation, which is evident in the appearance of bubbles at the surface
- Surface displays like tail slapping
- A female attempting to shield a calf with her body or her movements
- Sea turtles
- Rapid retreat into the water by a resting turtle on land
- Changes in swimming, such as rapid change in speed or direction
- Abandonment of a nesting attempt by a female turtle
- Change in direction of hatchling turtles on land, such as moving towards a light or a distraction instead of towards the water
- Sharks
- Arched back
- Downturned pectoral fins
It’s important to note that animals do not always exhibit a change in behavior when they are distressed. For example, some animals may freeze when they feel threatened. You should also limit time spent observing a group of animals or an individual animal to 30 minutes or less. When in doubt, assume that you are too close for comfort and take a few generous steps away from wildlife.
