Swallows

I looked up swallows on the internet, and I found the post at http://www.bayjournal.com/article/swallows_chaotic_maneuvers_part_of_precise_feeding_flight.I like the part that says, "The centrifugal forces in my life pull me in a thousand random directions. At times I fear that I will simply fly apart. This little haven of water and fields and birds helps to hold my vital center."
