Regarding Paul Klassen's interesting post about Bald Eagles and Starlings in conflict, here's a recent article about modeling starling flock behavior using techniques developed in particle physics: http://ptonline.aip.org/journals/doc/PHTOAD-ft/vol_60/iss_10/28_1.shtml I don't have any experience with starling flocks going after eagles, but this might shed some light on how they manage the flock.
