The blueberry is perhaps the most perfectly desirable food for pest birds. Blueberries are nourishing, sweet and easy to grab. Sparrows, Starlings and Crows are particularly attracted to this crop.
Blueberries are such a draw for pest birds that data shows that an unprotected field can lose 20 – 80% of the crop. Even netted fields can lose 8 – 10% of the crop.
Falcons must be flown more intensely than on other crops. Several Falcons are required, preferably of different species, in order to convince pest birds to just “move on”.
