Shooting
The annual cost of installation and retrieval of nets is relatively high, especially if a contractor is used. The total cost for installation and retrieval of the nets is around $1,000 per hectare for four-row or full-block cover, or around twice that for single-row netting. This includes hiring a net application machine.

Some growers believe that every dead bird is one less to eat fruit and that destruction is an effective method of pest control. In fact, shooting is not usually effective - or cost effective. Other birds soon move in to replace those that have been killed, so to achieve any long-term reduction in bird numbers it would be necessary to reduce bird populations by at least 90%. This is neither practical nor acceptable. Shooting is also potentially dangerous to the operator and other workers, and can be offensive to neighbours and the wider community.
