Sea lions in San Fransisco have vanished

Ever since 1989 the number of sea lions on Pier 39 were increasing. Because of the big number of sea lions they had to start remove all the boats on the pier, it left big open spaces where the sea lions could move in.

In November 2009 they have counted about 1500 sea lions. Now something misterious has happened, they are nearly all gone. They are not certain why but they think that they left for the winter and they will return in the spring. It was a big tourist attraction in San Fransisco. A lot of people came to the Pier 39 just to view the sea lions. Does it have something to do with the global warming? Will they come back? I will keep you posted.
