Up come the dolphins, and drop off the rope, yay.

They're outside the dolphin's normal repertoire, but they're easily mimicked by the dolphins.

(Whistle)

The dolphin's at the keyboard.

Killing dolphins in Futo, Japan

Now, dolphins are natural acousticians.

And they use these clicks to hunt and feed.

So just take a guess in your mind which one is the dolphin.

Dolphins, pretty big brains, play a lot.

For example, in oceanography, a lexicon of dolphin language is actually being created by basically visualizing the sonar beams that the dolphins emit.

Now this is some video of a typical dolphin fight.

Two are human words, and one is a dolphin vocalizing.

I'm going to drop the rope, see if they come over.

like I described for the dolphins.

Next user group are the dolphins at the National Aquarium.

How many of you here see dolphins? Raise your hand if you see dolphins.

So it could have a negative impact on the whole population.

Then we showed it in dolphins, and then later in elephants.

The dolphins are pretty intrigued as to what's going on here tonight.

By the way, if you're also a student at CalTech they also tend to just see the dolphins.

And in some parts of the world, they use tools,

So dolphins are also political animals, so they have to resolve conflicts.

Now, these are bottlenose dolphins, and you'll see them starting to synchronize their behavior and their sounds.

Likewise, we can create our own whistles, our own whistle names, and let the dolphins request specific divers to interact with.

They also run the Dolphin and Seal Centre along the coast at North Kessock.

Now, I want to return to dolphins, because these are the animals that I feel like

We have a lifelong emotional and financial commitment to our Asian Elephant partners.

Now, will they learn to mimic the whistles functionally?

This plot shows two members of a pair.

And so we see changes in the spinner dolphins that are related to the changes we're seeing in the plant life.

Now, in the Bahamas, we also have resident bottlenose that interact socially with the spotted dolphins.

But again, neither humans or dolphins are very amenable to control physiological experimentation.

And the last day, the sun comes out, the Orcas come, they're right by the boat. It's fantastic.

And two boats When the second boat was added, what happened was that some of the dolphins left the area completely.

Now, the signature whistle is a whistle that's specific to an individual dolphin, and it's like a name.

Well, CHAT is designed specifically to empower the dolphins to request things from us.

What this figure shows is the percentage of the separations in which dolphins whistle, against the maximum distance.

Here in So Cal, another one of vocal learning friends are dolphins.

OK, those people who raised their hands, afterwards, the rest of the audience, go talk to them, all right?

And the last day, the sun comes out, the Orcas come, they're right by the boat.

How many of you here see dolphins? Raise your hand if you see dolphins. OK, those people who raised their hands, afterwards, the rest of the audience, go talk to them, all right? Actually, this is the best example of priming by experience that I know.

Whales also have contact calls like I described for the dolphins.
