Hi Jim & All, Sept 14, 2007
Usually within 24 hours, as I recall from some years ago, Ravens &
Crows will clean up a pile of deer guts and I have seen them flying in
the right direction an hour or so after a kill. I have assumed that
smell was the mechanism for locating the food, as opposed to sight
largely because, in woodland with significant small coniferous cover,
some piles would be almost entirely hidden from view.
