Why do wolves howl? - http://www.slate.com/blogs...
"Of all the myths that dog the wolf, none is more widely accepted than the idea that wolves howl at the moon. Images of wolves with their heads upturned, singing at the night sky, are as unquestioned as a goldfish’s three-second memory or a dog’s color-blindness (both also myths). There are countless depictions of moon howling in faux Native American tchotchkes; the scene also appears in Jack London novels and at least one Los Angeles piano bar. This curious fiction has become so quotidian that even The New Yorker’s legendary fact checkers let “a long, lamenting howl at the orange moon” slide into print without a second thought. The truth is that wolves—the real-life, Canis lupus variety—don’t howl at the moon. Scientists have found no correlation between the canine and Earth’s satellite, except perhaps an increase in overall activity on brighter nights. So how did the idea gain such traction, and what do wolves howl at?" - Jessie
