Does a woodchuck have nickname?

Woodchucks don't really have a widely recognized nickname. They are sometimes called groundhogs, but that's just another name for the same animal, not a nickname.

There are some regional or colloquial nicknames for woodchucks, but they are not widespread. For example, in some areas they might be called "whistle-pigs" due to their high-pitched whistle.

So, while there are no official or widely known nicknames for woodchucks, people do sometimes use descriptive or playful terms to refer to them.
