Anserinis

Anserininae is a subfamily of waterfowl belonging to the Anatidae family. The subfamily consists of geese and their allies, including brant geese and roggenwijngans. These birds are characterized by their robust bodies, thick necks, and black heads with white markings. They are generally found in wetland habitats, including marshes, rivers, and coastal areas, where they feed on a variety of plants, including grasses, leaves, and aquatic vegetation.

The Anserininae subfamily is divided into four genera: Anser, Branta, Cackling goose, and Greater White-fronted Goose. These genera are geographically widespread, with species found in Europe, Asia, Africa, and the Americas. Anserininae are social birds that often form large flocks, and they are known for their distinctive honking calls. They are also migratory birds, with many species moving between their breeding grounds in the Arctic tundra and their wintering grounds in warmer regions.

Anserininae are affected by various threats, including habitat destruction, hunting, and climate change. As a result, some species are listed as endangered or vulnerable by conservation organizations. Efforts are being made to protect and conserve these birds, including the establishment of protected areas and the implementation of sustainable hunting practices. Anserininae play an important role in their ecosystems, helping to disperse seeds and maintain wetland habitats, and their conservation is essential for maintaining the health of these ecosystems.
