SAN FRANCISCO (CBS 5) — At the ballpark, it’s all about timing. But we’re not talking about the players. Whitney Gould asked this Good Question: How do seagulls know when to show up at AT&T Park at the end of a Giants game?

ANSWER: According to Dan Murphy of the Golden Gate Audubon Society, seagulls are actually quite intelligent. They use auditory signals and other cues to know when the end of the game is coming. Seagulls can see people leave the stadium and automobiles begin to move near the ballpark, which is a cue that food will be plentiful in many of the seating areas.
