A system for limiting access by flying animals to fans of an air-cooled condenser comprises a plurality of perimeter netting segments and interior netting segments. The fans are mounted on a framework and arranged in a matrix. Each fan comprises either (i) a perimeter fan positioned along any one of three or four outer edges of the matrix or (ii) an interior fan. Each perimeter netting segment is adapted to be positioned at least partly below a corresponding one of the perimeter fans. Each interior netting segment is adapted to be positioned at least partly below a corresponding one of the interior fans. Each perimeter netting segment has a first edge adapted to be affixed to the framework and a second edge affixed to a corresponding interior netting segment. At least a portion of each perimeter netting segment is angled inward and downward toward its corresponding interior netting segment.
