Narrative:
On final approach (visual approach) to oak runway 30 at approximately 1400 feet MSL; we noticed what appeared to be a small flock of birds slightly to the left of our approach course. It was low and located between the runway threshold and the aircraft.the object(s) appeared to be black in color continued to climb in a southwest bound direction over the bay. At approximately 1200 feet MSL; the object began a rapid acceleration and aggressive climb. The autopilot was disconnected in case any evasive maneuvering would be necessary. The object made a rapid westerly climbing maneuver passing off the left side of the aircraft between 1200 and 1000 AGL. The object became clearly visible at that time; it was a black quad copter drone. The drone passed off the left side of the aircraft by approximately 500 to 1000 ft. We immediately relayed the information to the tower and continued the approach to a normal landing. During taxi in provided ground control with any additional information; they requested. Drone operating within the airport traffic area. It appears to be very difficult for airport authorities to secure the airport area from incursions by drones. Crew awareness is probably the only realistic defense against such incidents. Drones may become as numerous and hazardous as birds and other wildlife threats.
