Anatidae

These birds primarily target winter cereals like wheat and barley, as well as early-season shoots of oilseed rape and corn. The nutritional requirements of these birds, particularly during migratory stopovers, drive them to exploit the highly accessible and nutrient-rich biomass of young crops.

The biology of Anatidae is intrinsically linked to aquatic environments, but their feeding habits are highly adaptive. During the growth cycle of a crop, the presence of large concentrations of waterfowl can cause rapid depletion of plant populations, especially in fields located in close proximity to major wetlands or nesting sites.

Damage is characterized by the consumption of tender shoots and trampling, which results in soil compaction and the destruction of seedling stands. This physical impact stunts the growth of remaining plants, increases vulnerability to disease, and creates uneven crop density, which complicates harvesting processes.

Integrated management is essential for mitigating these risks. Farmers often employ a combination of non-lethal deterrents, including propane cannons, bio-acoustic devices, and visual repelling agents like hawk kites. Furthermore, field management practices such as planting timing adjustments can help avoid the peak presence of migratory flocks.
