This is the sound a Roe Deer makes - https://www.youtube.com/watch?v=esbuHz0Jmko - which in appearance is very much like the deer we see in Valheim. I am surrounded by deer all day long, working and playing at a prestige golf course in Pitt Meadows. They do sound a lot similar to the deer in the game. They only move away from me when my 5 blade Toro 4300 https://www.toro.com/en/golf/rough-mowers/groundsmaster-4300, gets within 3 or 4 metres. Watching them eat blackberries is a wondrous privilege during downtime.

There are so many animals at this course, that when an animal like a deer dies, all that remains of the carcass after a day or 2 is a handful of rib bones and a few vertebrae.
