Bird Damage in Tree Fruits
Anne Mills, Field Technician
Eastern New York Commercial Horticulture
Frugivorous birds impose significant costs on tree fruit growers through direct consumption of fruit and
grower efforts to manage birds.We documented factors that influenced tree fruit bird damage from 2012
through 2014 with a coordinated field study in Michigan, New York, and Washington. For sweet cherries,
percent bird damage was higher in 2012 compared to 2013 and 2014, in Michigan and New York
compared toWashington, and in blocks with more edges adjacent to non-sweet cherry land-cover types.
These patterns appeared to be associated with fruit abundance patterns; 2012 was a particularly lowyield
year for tree fruits in Michigan and New York and percent bird damage was high. In addition,
percent bird damage to sweet and tart cherries in Michigan was higher in landscapes with low to
moderate forest cover compared to higher forest cover landscapes. 'Honeycrisp' apple blocks under
utility wires were marginally more likely to have greater bird damage compared to blocks without wires.
We recommend growers prepare bird management plans that consider the spatial distribution of fruit
and non-fruit areas of the farm. Growers should generally expect to invest more in bird management in
low-yield years, in blocks isolated from other blocks of the same crop, and in blocks where trees can
provide entry to the crop for frugivorous birds.
