Snow Petrels (Pagodroma nivea). Cape Petrels (Daption capense), and Southern Giant Petrels (Macronectes giganteus) were also attracted although Antarctic Fulmars (Fulmarus glacialoides) passed by the lure without showing any awareness of it (Jouventin and Robin, 1984). The brains of these four species are shown in Fig. 2.
