One- to three-inch anchovies attract clouds of gulls, terns and even pelicans. Anchovies this size make up the classic baitball. The tighter the baitball, the tighter the flock of birds. These can be small flocks of birds on smaller baitballs or great flocks working big shoals of anchovies. Albies pick at the edges, making the ball of bait and birds tighter. After slashing the outside of the ball, they will eventually blast through the ball itself. When Spanish mackerel and/or bluefish show up, they tend to crash through the ball and spread the bait over a larger area. The birds will be manic and spread out as well.
