Bluebird versus caterpillar. Guess who won...

I took this short video (0:17) of a bluebird just after it caught a caterpillar.  Because of the way the morning light was shining, you can only see a silhouette of the bluebird as it struggles to subdue the insect and manipulate it into the proper position to either eat or - more likely - take back to the nest to feed its young.
