There has been an unusually large number of pelicans by the dam on Doty Island this year.  I estimate 300-400!  Not sure why but they sure put on a show.  We went bird watching in the evening and I planned ahead and brought my 70-200 with a 2X teleconverter.  This shot was taken at 400mm and the bird flew directly overhead.  The feather detail is just amazing.  These birds are so big and such wonderful fliers.  God sure is amazing when he solves an engineering problem! 

With the extender the lens is a f/5.6 so with the lateness and the need for high shutter speed (to freeze motion) I ended up at 500 ISO.  No problem with the 5d!  The focus here was set to servo and I tracked using the center “cross type” focus point.
