I've often thought that the name "muskrat" for this smaller cousin of the beaver is not the most complimentary term.
This little rodent who frequently co-habitates with its beaver cousin, will make repairs to their lodges and often appears in open water just before beavers make their presence known. Perhaps, the muskrat acts as a semi-scout, checking out for an "all clear".
Unlike beavers, however, muskrats are not solely vegetarian and will also eat small fish, snails, clams, etc. when the need arises. I have included a photo that I took in March 2022 of a muskrat with its catch (Photo #7).
So how about a name change? As you can see from the photos below, they have similar harvesting habits as beavers and this particular muskrat seems to be particularly pleased with its choice (Photo #2 & Photo #3).
My suggestions in no particular order:
1. Muskbeaver
2. Lesser Beaver
3. Micro or Mini Beaver
