A bird repellent system comprising a shaft and shaft base installation securely fastened to a tower, wherein the shaft base comprises a tubular projection that is perpendicular to the shaft base into which the shaft is inserted and held upright. The shaft comprises bores running through the interior of the shaft, through which links can be formed to create a mesh or grid pattern to repel birds from landing or roosting and nesting on top of, or in, a tower structure. The shaft can comprise a cross-shape cross section whose base acts as a male part to a corresponding female part on the tubular projection to prevent the shaft from shifting around. Alternatively, the shaft can be screwed into, or fixedly connected to, a shaft base without the tubular projection. The shaft base can be securely fastened to the tower structure with screws, cords, nails, straps and/or magnets.
