The tundra swan (Cygnus columbianus) and the snow goose (Anser caerulescens) are two similar-looking birds that are often confused with each other just like “tundra swan vs snow goose_vr”. However, there are several key differences between the two species that can help you identify them in the field.
One of the most obvious differences between the tundra swan and the snow goose is their size. Tundra swans are significantly larger than snow geese, with an average weight of 12-15 pounds compared to 5-8 pounds for snow geese. Tundra swans also have a longer wingspan than snow geese, with an average wingspan of 6-7 feet compared to 5-6 feet for snow geese.
Another key difference between the two species is their coloration. Tundra swans are all white, while snow geese can be either white or blue. White snow geese are more common than blue snow geese, but both color variations are found in the wild.
Finally, the tundra swan and the snow goose have different habitats. Tundra swans breed in the Arctic tundra, while snow geese breed in the subarctic and temperate regions of North America. Tundra swans migrate to the southern United States and Mexico for the winter, while snow geese migrate to the southern United States and Central America.

Size
Size is one of the most obvious differences between tundra swans and snow geese. Tundra swans are significantly larger than snow geese, with an average weight of 12-15 pounds compared to 5-8 pounds for snow geese. Tundra swans also have a longer wingspan than snow geese, with an average wingspan of 6-7 feet compared to 5-6 feet for snow geese.
-
Weight
The average weight of a tundra swan is 12-15 pounds, while the average weight of a snow goose is 5-8 pounds. This difference in weight is due to the fact that tundra swans are larger birds overall, with a longer body and wingspan.
-
Wingspan
The average wingspan of a tundra swan is 6-7 feet, while the average wingspan of a snow goose is 5-6 feet. This difference in wingspan is due to the fact that tundra swans have longer wings, which they use to fly long distances during migration.
-
Body Length
