Bean goose

The Bean goose (Anser fabalis) is a migratory bird belonging to the Anatidae family and the Anseriformes order. While recognized for its role in biodiversity, its migratory habits frequently cause significant economic losses to farmers when large flocks forage on winter cereal fields.

This species primarily targets winter wheat, rye, and pasture grasses. Because Bean geese forage in large groups, they consume significant quantities of green biomass, which acts as a vital food source during their long-distance migration phases in early spring and autumn.

The biology of the Bean goose is characterized by strong social grouping and high site fidelity during stopovers. They are highly attracted to open, flat agricultural land where visibility is high, allowing them to detect predators easily while grazing intensively on the young shoots.

Damage caused by Bean geese is characterized by the complete removal of the green part of the plant, which may prevent recovery and lead to stand thinning. In severe cases, the intensive trampling and compaction of the soil by the flock inhibit the growth of the remaining plants, leading to uneven crop development.

Integrated bird management strategies focus on non-lethal deterrents to protect high-value crops:

• Deploying propane cannons and acoustic deterrents to disrupt feeding behavior.
• Utilizing visual markers like hawk kites, predator decoys, or reflective streamers.
• Strategic land management, including planting decoy crops to lure geese away from essential production fields.
