Abstract
Among small fruit crops, blueberry production often experiences some of the highest levels of yield loss due to avian damage. Many currently available bird deterrents are cost-prohibitive, unsuitable for use near residential areas, or become ineffective due to bird habituation. One emerging technology that may address these limitations is the University of Rhode Island’s (URI) Laser Scarecrow. To evaluate the efficacy of the URI Laser Scarecrow system in blueberries, two adjacent field trials were conducted at the Rutgers Philip E. Marucci Center for Blueberry and Cranberry Research and Extension in Chatsworth, New Jersey. The site supported a diverse bird population due to proximity to woodland borders and cranberry bog canals. The predominant bird species observed were red-winged blackbirds (Agelaius phoeniceus) and brown-headed cowbirds (Molothrus ater). Fields were divided into two blocks consisting of an untreated control and a laser-treated area. Branches were randomly selected within each block and pre-harvest berry counts were conducted. Berry counts were recorded across four harvest events, and the percentage of berry loss—most likely attributable to bird damage—was calculated following the final harvest. Both fields showed reduced berry loss in the laser-treated blocks compared with controls. In Field 1, the laser treatment experienced 9.10% yield loss compared with 18.40% in the control. In Field 2, losses were 19.38% and 25.01%, respectively. A two-way ANOVA indicated significant effects of field location (p = 0.02) and treatment (p = 0.04), while the interaction between field and treatment was not significant (p = 0.66). These results suggest laser-based deterrents may reduce bird-related yield losses in blueberry production, though additional field trials are needed to confirm effectiveness and develop standardized guidelines for grower use.
