damage is increasing because there is a better tasting dinner available
to them than before, and there is more of it. That is, sweeter grape
varieties are being planted and the total acreage is increasing. Early
season sweet cherry varieties are being planted to take advantage
of early market prices, and hungry birds find them quickly. In the
past, vineyards, fields and orchards were smaller and intermixed with
other crops, but today, they are much larger. Large flocks of birds
can all feast together without having to constantly forage. Finally,
bird populations are increasing, and there have been changes to migration
patterns due to climatic changes.
