Bird caps, which are devices installed at the highest elevations of the peaks of gabled roofs so as to prevent damage caused by the roosting habits of birds. Exemplary bird caps of the invention each comprise a peak formed by angularly connected side panels, opposed and adjustable face panels that may be moved apart or together to adjust the angle at the peak, a tail portion and a tail plate, each of which provides a further covering function to the area around a roof peak. In certain embodiments, the device includes hooded panels which further enhance the roof peak protection provided. Also disclosed are methods of preventing the bird damage and deterioration at the peak edges of a roof.

The invention relates to a cooling panel assembly (2) for a wind turbine tower (1). It is arranged to be mounted on such a tower (1) on a section thereof as seen in the circumferential direction. The cooling panel assembly (2) includes at least one cooling panel (2a,2b). According to the invention, the cooling panel assembly (2) includes deflector means (6) mounted at the top of the at least one cooling panel (2a, 2b) such that the deflector means (6) shields the cooling panel assembly (2) from above. The deflector means (6) has substantially the same circumferential extension or more as the other parts of the cooling panel assembly (2). The invention also relates to a wind turbine tower (1) provided with at least one such cooling panel assembly (2).

An anti-bird cover for a watercraft uses planar sheet of plastic netting with a small, but not micro, aperture to deter birds from perching. The aperture is formed by a plurality of filaments and knots. The filaments are between 0.25 and 2.00 in length, with the illustrated embodiment having filaments of 0.75. The plastic netting is formed from nylon, polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). The perimeter of the netting is encircled by an elastic gather with two free ends. The two free ends of the elastic gather are captured by a bungee cord stop. The surface area of the planar sheet of plastic netting is 1.5 time the surface area of the watercraft to be covered, in order to make the present invention billow in the wind, thus deterring birds from perching.
