One day I noticed one of the young whales appeared to have come up with a procedure for luring gulls down to the pool,'' the professor said. I found it interesting so I noted it in my log.'' <o =""></o>
First, the young whale spit regurgitated fish onto the surface of the water, then sank below the water and waited. <o =""></o>
If a hungry gull landed on the water, the whale would surge up to the surface, sometimes catching a free meal of his own. <o =""></o>
Noonan watched as the same whale set the same trap again and again. <o =""></o>
Within a few months, the whale's younger half brother adopted the practice. Eventually the behavior spread and now five Marineland whales supplement their diet with fresh fowl, the scientist said. <o =""></o>
It looked liked one was watching while the other tried,'' Noonan said of the whale's initial behavior. <o =""></o>
The capacity to come up with the gull-baiting strategy and then share the technique with others -- known as cultural learning in the scientific world -- was once believed to be one of those abilities that separated humans from other animals. <o =""></o>
