One of the greatest migrations on Earth
- A narrow stripe of cold water near the coast, pushed to the coast by warmer water in the ocean: sardines are pushed together, and dolphins can make "baitballs" out of them - separate shoal of fish, shaped in a form of giant ball. If they make it - a feeding feast starts: common dolphins, cape gannets, bronze and dusky sharks, and even Bryde's whales start eating them, charging throw baitball with open mouths. Baitball can last from typical several minutes to 4-5 hours.
- Not very strong wind - if the wind is strong, birds can't fly, so you can't find a baitball.
- Good sun - for photography.
- And the main thing: good dense baitball, which is not moving very fast. Frequently all action happens on a territory too big: dolphins easily purse the fish 200m to one side, than 300m to the other side... I jump into that - they fly around me in a few seconds and that's it, I have to go back on boat. Jump again, go back, and so on.
