Bird observation cabins have been set up 1000 meters away from the spot in the middle of the estuary where the spoonbills rest. Only 700-plus black-faced spoonbills now survive in the world, but over 500 have been recorded together at this spot.
距設置於曾文溪口賞鳥亭的一千多公尺外，即是黑面琵鷺的棲息地，目前全世界僅餘七百多隻的黑面琵鷺，曾有多達五百多隻來此棲息。
