source of natural wonder, and totally sweet long panning shots for nature 
documentaries.&nbsp; But now it seems that the avian autopilot is of interest to 
science, and possibly the X-Men - because the birds might have QUANTUM <SPAN

separation is constantly being checked by the bird prevents it from recombining 
as quickly as normal.&nbsp; This is a known quantum effect, an utterly 
scientific version of "a watched pot never boils"</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2008/05/birds-quantum-m.html">It's like driving the family car, but every time a kid asks "Are we there yet?"
