I believe that we are having a problem with semantics. Reference:
https://en.wikipedia.org/wiki/Marmot- Marmots are large squirrels in the genus Marmota, of which there are 15 species.
Read the whole reference; not all 15 species are found in the United States. When I hear, or read the term “ground hog” or “woodchuck”, in my mind I picture
Marmota monax. The term “marmot” suggests
Marmota flaviventris while ““whistle pig” could refer to either.
Unless we refer to the Latin name for a critter we are sometimes left wondering what the poster is talking about. How many different animals are referred to as “gophers”. Even the taxonomists don’t always agree on animal classifications.
Now we have cell phones to compound the problem. I often have no idea of what the poster is trying to say. Don’t folks proofread what they have written before posting???
