There is no single solution to the problem of bird damage to crops. What works well in controlling birds on one property may be ineffective on a neighbour?s place. Also, the number and variety of pest birds not only vary from place to place according to local conditions, but also with seasons.
In deciding which damage reduction techniques to adopt, each grower should use local knowledge and match it with his/her own circumstances. Before you choose a strategy, it is important to know your opponents. Do not treat all pest birds as if they were a single species. You do not treat all weeds as a single species, all insects as a single species or all mildews as a single disease. Birds differ greatly in their ecology and behaviour, and this influences the ways in which they respond to different forms of control. For instance, some species, such as the Adelaide rosella, live in pairs or small family groups and remain within a small area all year round and are therefore hard to shift. Others, such as the starling, form large flocks, which are highly mobile and move with the seasons from place to place and are usually easier to move on.
The main damage reduction actions available to growers are:
- scaring/deterring birds,
reducing bird numbers,
excluding birds and
crop/habitat management to influence resources available to birds.
