Bean Goose

Bean geese occur across Europe and Asia. Their several subspecies breed in northern Europe and Siberia, while Asian populations winter in places including western and eastern China, Japan, and Korea. During spring and summer they use cold tundra and taiga landscapes near lakes and marshes. Wintering birds commonly occupy large fields, agricultural land, lakes, and wetlands. Adults measure about 65 to 90 centimeters long, span 140 to 190 centimeters, and typically weigh between 2.8 and 3.4 kilograms. (Animal Diversity Web)

These geese are herbivores that feed on grasses, seeds, roots, tubers, and crops such as corn, rice, barley, wheat, soybeans, potatoes, and sugar beets. Bean geese select partners by their second winter and generally mate for life, reinforcing pair and family bonds through shared displays and calls. They breed once annually and lay four to six eggs, which hatch after 27 to 29 days. Both parents usually raise and protect the goslings, which fledge at about 40 days. (Animal Diversity Web)
