Studying Whales with Drones

Counting whales has gone to the drones.  

After years of struggling to survive, the gray whales that migrate along the western Pacific coastline—from the Bering Sea to the Gulf of Mexico—are now under the watchful eye of a hexacopter drone.

Dedicated professionals and volunteers count the migrating gray whales every spring.  It’s been an imperfect count because they can’t always count whales swimming by at night or in stormy weather.  Fortunately, the new whale mothers swim very close to the shore when they take their new calves on their first big swim from Mexico to Alaska.

The drones add an extra “eye” that helps scientists measure the passing whales and observe the mother’s weight and health.

These camera-equipped drones also track orcas (killer whales), sperm whales, blue whales, stellar sea lions, leopard seals and penquins in Antarctica.

What If There's a Seal on the Beach?

If you visit the beach this summer, you might see a seal on the beach.  What do you do if you see one?

Here's a few tips for your safety and the safety of the seal on the beach.

1) All seals are wild animals.  They have very sharp teeth.  Keep far away from seal on the beach.

2) Try to look at the seal with binoculars.

3) Do not touch the seal.

4) Do not throw rocks at the seal. 

5) Keep your pet away from the seal.  Keep your dog from barking at the seal.

6) Don't chase the seal if it is moving around.

7) Be sure that you are not between the seal and the water.  The water is the seal's first escape route.  You could get hurt.

8) Do not try to feed the seal.  Actually, it's a good idea to not feed any wild animals like birds and squirrels.

9) All marine mammals in United States waters are protected by law. That's one reason why you should stay away from them.

10)  Some sea lions might be sick this summer.  If you see a seal that looks sick, contact an authority. In the United States you can call 1-800-853-1964 and report the seal.
