Wolves are skilled and ferocious hunters, but when it it comes to
relationships, they're real softies. When a playmate or partner
leaves the pack, the wolves that are left behind will howl and
howl and howl.
In a new study, researchers report that wolves will give their
leaders and their closest allies a longer and stronger serenade if
they leave. Those howls could be sonic breadcrumbs, meant to help
a lone wolf find its way back to the pack.
