Narrative:

While on a visual approach for approximately 10-15 miles northeast of the airport we experienced a near mid-air collision with two hang gliders at approximately 2;300 feet. The first officer spotted the hang gliders and I then saw one at our altitude black and orange in color. As we turned I saw a second glider green and yellow at a higher altitude. The entire event took place over a few seconds and we did not see them until moments prior to the reaction.the first officer had spotted the hang gliders and recognized their direction of travel and said to turn left. I disconnected the autopilot; initiated a left turn; and confirmed his assessment. It was a fairly aggressive turn to avoid a potential collision. I believe we came within a few hundred feet of the glider. I understand these hang gliders were outside the airport's airspace; however; they should use better judgement flying so close to an approach corridor into an a fairly busy airport.
