I think the honeyguides cooperate with ratels more often than
humans. It
also seems to be well documented that ravens will lead predators
(including humans) to suitable prey, presumably in order to get a
carcass to scavenge.

There are probably several such ccoperative relationships between
species. The one that comes to
mind immediately though is that between Prodotiscus insignis (the
honey
guide bird) and Homo
sapiens.
