Ducks vs. Geese — What's the Difference?

Ducks are typically smaller than geese, possessing shorter necks and more compact bodies. They often have a broader range of vibrant colors and a more varied diet, which includes aquatic plants, insects, and small fish. Geese, on the other hand, are larger birds with longer necks and more elongated bodies. Their plumage is generally less colorful, often featuring shades of gray, black, and white. Geese are primarily herbivores, feeding on grasses, grains, and aquatic plants.

Ducks usually inhabit smaller bodies of water such as ponds, lakes, and marshes. They are known for their dabbling and diving behaviors. Whereas geese are often found near larger lakes, rivers, and open fields, known for their strong migratory patterns and ability to travel long distances.

Ducks are more solitary or found in small groups, especially outside of the breeding season. Geese are highly social birds, often seen in large flocks, particularly during migration periods when they form V-shaped flight formations.

Ducks generally produce a softer quacking sound. In contrast, geese have a louder, honking call, which can be heard from a considerable distance and is often associated with their migratory behavior.

Ducks have a more varied mating system, sometimes exhibiting monogamy or short-term pair bonds, while geese are typically monogamous, forming long-term bonds that can last for several years.
