>damage to fruit crops.
As far as I am aware, netting to exclude birds is still the most effective
protect crops from birds. The economics of damage and its control needs to be
examined carefully to determine the cost benefit of this (or any other damage
control measures employed). If netting is not used, then a suite of measures
used in combination is usually necessary to minimise damage by birds.
This could include regular patrolling, use of Bird Frite cartridges, backed up
limited shooting of birds (otherwise they learn to ignore most noises/devices),
use of gas guns moved regularly and in some cases, provision of alternate foods
away from the crop. Taped alarm or distress calls may enhance the
effectiveness of such a strategy, if these are available.
These methods are used by some enlightened growers and, if they are prepared
to put in the time, damage can be reduced to very low levels.
You are probably aware of most of the above. There are no new developments
that I am aware of.
