Not sure about "animal", but the fungus Strobilomyces strobilaceus, also called Strobilomyces floccopus is commonly known as "old man of the woods".

Not sure where someone got their information that "owl" translates from or into "old man of the wood"...

The etymology of the name "owl" is that it comes from Old English ule by way of Middle English - originating from Proto-Germanic *uwwalǭ in imitation of a wail or an owl's hoot.
