UC Davis - How Bird Gard Reduced Crow Damage in Almond Orchards and Saved Thousands in Losses

Background
Almond orchards in Yolo County and Sutter County, California, faced persistent damage from crows, leading to substantial crop losses each year. Dr. Paul Gorenzel, a horticulturist at the University of California, Davis, conducted a study to evaluate the effectiveness of Bird Gard’s bioacoustic technology in mitigating bird-related losses.
The Challenge
Before implementing Bird Gard, almond growers in the study suffered heavy financial losses due to crows feeding on their crops. Losses varied widely, with some orchards losing as much as $1,015 per acre to bird damage. Growers needed a solution that could effectively deter crows and prevent them from returning to the orchards.
The Solution
Dr. Gorenzel and his team introduced Bird Gard’s bioacoustic technology to five almond orchards across Yolo and Sutter Counties. The results were striking:
- Complete Crow Abandonment – Crows virtually abandoned two orchards in Yolo County after Bird Gard was introduced.
- Sustained Bird Control – In three other orchards in Sutter County, crows stayed away, significantly reducing crop damage.
Dramatic Reduction in Losses – Almond losses dropped from a previous range of $46 to $1,015 per acre to only $22 to $138 per acre.


The Results
- Crow damage significantly reduced across all orchards
- Total financial savings of $998, $3,642, and $5,914 for three individual orchards
- Sustained protection with Bird Gard distress calls
Conclusion
Bird Gard’s bioacoustic technology provided a highly effective solution for reducing crow damage in almond orchards, leading to substantial financial savings. With crows abandoning some orchards entirely and avoiding others, Bird Gard proved to be a cost-effective, long-term bird control method for almond growers in California.
