ABSTRACT:
A shelter to protect a crop from birds. The shelter comprises uprights including end uprights arranged in longitudinal rows in a crop area. There are guides on the top of each upright. A pair of upper main guide wires extend between tops of adjacent uprights in each longitudinal row and are located by the guides. Cross wires extending between adjacent end uprights. Monofilament nets extending between adjacent pairs of guide wires. The nets form a roof for the shelter and are secured to the cross wires. There are loops at the side of each net to engage the guide wires. Further monofilament nets are mounted in the cross wires and extend downwardly to form ends for the shelter. Other monofilament nets extend downwardly from each outer main upper guide wire of the shelter to form sides for the shelter. The nets are effective in preventing birds reaching the crop, durable yet inexpensive.
