This grebe caught three European Perch while I was watching (and the other adult grebe caught one), and it was so fun to watch, so forgive the profusion of photos. It kept trying to feed the fish to its three babies, and two took some somewhat reluctantly (I assume this had been going on for some time before I arrived as well and they were stuffed), and then it finally ate the last one for itself when none of the babies would take it (last two pics).
