R. Darwin 1908 Lesser Frigatebird Mc, Keen Island 275/ 1820 Turned 6° beam + a slowly ten drive an ambush for 11 seconds - unsuccessful. 1824 Three as 6° beam, drive an ambush for 16 seconds, successful. 1822 3 ad 8° Frigate, accompanied by 3 C. noddies drive a wedge tail for some 8 seconds - successful, but I could not determine whether a frigate or a noddy got the food. 1824 4 ad 8° beam, drive an ambush for some 15 seconds, send it splashing into the water + then they rose, about then a Noddie chased the ambush for some 15-20 yds when 'it rose from the water'. 1827 4 ad 8° beam, driving in, mixed combination, 2 ambushes - finally one got away - other chased until it disappeared - two C. noddies got in the fray about 60 yds away and leaped in to get the dropped food, but died; the frigates beat them to it - both noddies were chasing the 2nd ambush as actively as the frigates. 1829 2 frigate and a noddy drive an ambush, at distance, and one of the frigates drops to set it. The frigate rises. C. noddie still continues to drive ambush for about 30 yds. 1831 One frigate and 3 noddies, during an ambush and it ended in a mad thrashing on the surface. Did not know what happened. 1873 I weary of this game and set it getting too dark to see clearly. In all the above chases, concerning terns, one epoil strike Clean in that a tern (either noddy or doty) was seen noted to indicate a chase. Only after one or more frigates had started the chpc, would one or more terns join in, but the noddies regularly chased the prey until after the frigates had quit.
