When most cats go after a bird, the bird usually loses. Not this time. While the cat tried to corner the crow, the crow simply hopped on a different branch and then taunted the poor cat as it tried to keep the crow in sight as it flew around, nipping at its tail.

Perhaps this shows that cats should only pick on prey small enough not to fight back. Or it shows that sometimes you can win by standing up for yourself no matter what the odds might be.
