I told you Matt - who owns Flynn - was off being  a humming-bird in Chicago (surely this has to be the title of his autobiography?) but I really wasn't sure what that involved...

However, here is the scoop: http://neighborhoods.redeyechicago.com/lincoln-park/news-report/2011/08/16/life-size-birds-nests-become-home-to-tv-crew-at-zoo/ 

Still not convinced I am any the wiser...
