The year 2021 ended somewhat unexpectedly sound-wise. From the reeds along a small canal
I heard sounds that sounded like the muffled mooing of a cow. It turned out to be Nutrias
Nutrias are rodents from South America, so they are considered an invasive species in Europe.
The populations here are offspring of animals abandoned by fur hunters in the past. The species
is now widespread, actually harmless, but quite unpopular with humans. I heard these sounds
for the first time.
