Caterpillar control

I really like these Galapagos Mockingbirds. They're everywhere here and they provide endless entertainment. They defend their little patches of territory against all intruders, dangerous or benign. I saw one have a tete a tete with an ani bird (http://en.wikipedia.org/wiki/Ani_(bird)) this morning. This one below has hit the jackpot with a juicy caterpillar and seems to be taking its frustrations out on the caterpillar by whacking it to death. We never said nature was nice… beware the overly sentimental statements people make about animals...
