Researchers have found that American kestrels, one of the smallest falcon species in North America, can help keep cherry farms safe from food-borne illnesses by preying on small birds that carry pathogens. The study, published in November, suggests that kestrels lower the risk of food-borne illnesses from pathogens, with orchards featuring nesting boxes for kestrels seeing an 81% reduction in crop damage and a 66% decrease in branches contaminated with bird droppings.
Farmers have been using kestrels to manage pests on their cherry farms for decades, and the birds' presence has proven to be effective in deterring unwanted bird species. The study's findings also suggest that kestrels can help reduce physical damage to crops, with orchards featuring nesting boxes seeing a significant decrease in damaged fruit.
The research was conducted by a team of scientists at Michigan State University, who evaluated 16 sweet cherry orchards in Michigan's Leelanau and Grand Traverse counties. The study found that the presence of kestrels significantly reduced the risk of food-borne illnesses from pathogens carried by small birds.
According to Olivia Smith, lead study author and assistant professor of horticulture at Michigan State University, "Kestrels are not very expensive to bring into orchards, but they work pretty well" at deterring unwanted bird species. The study also found that the presence of kestrels can reduce the need for pesticides and other chemical controls.
The use of kestrels as a pest management tool has been shown to be effective in reducing crop damage and improving food safety on cherry farms. By providing nesting boxes for kestrels, farmers can attract these birds and benefit from their predatory services. The study's findings suggest that this approach is not only cost-effective but also environmentally friendly.
The researchers recommend that farmers facing pest-management issues consider building kestrel boxes, which cost about $100 per box and require minimal maintenance. With the abundance of kestrels in Michigan's cherry-growing region, 80-100 percent of nesting boxes become inhabited by these birds, making it an attractive strategy for farmers looking to manage their crops sustainably.
