What is the life span of a goose?

Geese are waterfowl belonging to the family _Anatidae_. There are numerous goose species, and their lifespans can vary depending on the species and environmental factors. Here are the lifespans of some common goose species:

1. Canada Goose (_Branta canadensis_): Their average lifespan in the wild is about 10 to 25 years. However, some individuals can live up to 30 years.

2. Snow Goose (_Chen caerulescens_): Snow geese have a typical lifespan of 10 to 15 years in the wild, but some individuals can live longer, up to 20 years or even more.

3. Barnacle Goose (_Branta leucopsis_): Barnacle geese typically live for 20 to 25 years in the wild. Exceptional cases have been recorded of individuals living up to 30 years or slightly longer.

4. Greater White-fronted Goose (_Anser albifrons_): The lifespan of Greater white-fronted geese in the wild ranges from 15 to 20 years. However, it's worth noting that certain individuals might have longer lifespans, approaching or exceeding 30 years.

5. Emperor Goose (_Chen canagica_): The Emperor goose has a comparatively shorter lifespan, with an average of 8 to 12 years in the wild. However, some individuals can live up to 15 years.

6. Greylag Goose (_Anser anser_): Greylag geese have a lifespan of about 15 to 20 years in the wild, but longer lifespans have been reported in some cases, potentially exceeding 25 years.

7. Mute Swan (_Cygnus olor_): Although Mute Swans are not geese, they are also waterfowl belonging to the same family. Mute swans tend to have longer lifespans, ranging from 20 to 30 years in the wild, with some individuals living even longer.

It's important to note that while these are general ranges for goose lifespans, individual geese may vary in their longevity due to factors like habitat quality, food availability, predation, disease, and accidents.
