Greater white-fronted goose

The Greater white-fronted goose (Anser albifrons) is a migratory bird belonging to the order Anseriformes, family Anatidae. During their migration cycles, these birds can become significant agricultural pests, causing substantial economic losses by congregating in large flocks on arable lands.

The primary crops affected by these geese include winter cereals such as wheat, barley, and rye. In addition to grains, they frequently feed on sprouting oilseed rape and various grasses. Young, nutrient-rich vegetation is particularly attractive to them, making early-season crops highly vulnerable.

Regarding their biology, the species is highly social and follows consistent migratory routes. Their foraging behavior is intensive; they return to the same feeding grounds repeatedly until the available food source is exhausted, which is a major challenge for farmers managing large acreage in the migration path.

The damage character is characterized by the total removal of green biomass by grazing. Furthermore, the sheer weight of a large flock causes soil compaction and mechanical damage to the crop, which can lead to thinning of the stands and significantly reduced yields at harvest time.

To protect agricultural assets, farmers must employ a multifaceted strategy. Effective control includes:

• deploying visual scarecrows and reflective materials;
• using electronic bio-acoustic devices to simulate predator threats;
• utilizing automated propane cannons;
• implementing systematic field monitoring during peak migration windows.
