A fascinating and important work of ornithology, which led E.O.
Wilson to call it "one of the most interesting discoveries I've
seen in animal sociobiology in years," "Ravens In Winter" is a
scientist's impassioned study to understand the mysterious social
habits of one of nature's most formidable birds, the raven.
Why do ravens, generally understood to be solitary creatures, share
food between each other during winter? This was the question Bernd
Heinrich asked himself as he was observing another one of his prime
research subjects, the highly social bumblebee. And it was during
these trips to Maine, the site of much of his research, where he
first noticed this "unusual" behavior of ravens. From an
evolutionary perspective, the raven's willingness to share food
challenged conventional wisdom. There was no biological imperative,
it seemed, to their communal spirit. The more Heinrich observed
their habits, the more odd the bird's behavior became. What started
as mere curiosity turned into an impassioned research project, and
"Ravens In Winter," the first research of its kind, explores the
fascinating biological puzzle of the raven's rather unconventional
social habits.
