Here’s a fine photograph of a pack of coyotes who have chased two young pumas, aka mountain lions. The pumas found sanctuary on top of a large wooden fence – a rail fence – where they are in a standoff. They remained there for more than an hour. The puma is wonderfully athletic and used those skills to escape the coyotes.
You can see what appears to be a condor or eagle or some other very large bird in the top left hand corner of the picture.
These juvenile mountain lions are quite small and inexperienced. Adult mountain lions would have behaved differently. There is a balance of power going on and clearly five adult coyotes trump two young cougars.
Dogs hunting in packs are formidable. In Asia wild dogs in large packs can take on a tiger and win.
