- Some sharks are smart and do learn where to get an easy meal. I have
- a video by Mike deGruy which shows an island somewhere in the Pacific
- where Tiger sharks turn up once a year for the breeding of some birds.
-
- According to the film Tigers are never seen there except for those few
- weeks and during that time they ignore their normal prey while they feed
- on the birds.
-
- Their method is also interesting. If a bird's initial flight ends up in
- the sea it gets bitten, but not swallowed and no flesh is removed. The
- shark then goes away and returns and bites again until the bird either
- drowns or dies of the wounds. Then the shark takes the bird underwater
- to feed on it.
-
- If anyone is interested I will look out the details.
