Today I learned that squirrels can have “friends” among each other that often stay together within a territory for an extended period of time. Squirrels are often territorial, but since those territories often overlap and provide enough food for more than one squirrel, it’s possible that some of their kind get along with each other and even become “friends” or look after each other.
I came across this when watching this wonderful documentary by the wild life photographer Dani Connor. However, while it’s quite nice to see it in the documentary, I couldn’t find any further details on this behaviour in a quick online research. That might be due to my lack of good search terms for this behaviour, but it might be, that it’s just not a well-understood area in general. Either way, take 30 minutes of your time, and watch the documentary, you won’t regret it!
