Busy, busy little bee's.. nest building in progress

It always amazes me as to the speed and dexterity of these tiny creatures. These Anna's Hummingbird females zoom in to gather nest building material, tug and jostle , then zip off into the unknown with their prize.  I likely spent 2 hours waiting for shots today and though I did shoot quite a few, most of my attempts ended up without of focus images or completely missed chances because I  just  could not lock a focus before they were gone!
