(above statements occurred after leaving camp); there are hundreds or thousands of small (2-4 ft.) black-tipped sharks in the very shallow water near the beach - they almost beach themselves in their scurrying around; saw Blue-gray Noddies and Black-naped Terns at north end of Sibylla ; at 12:30 we crossed the three channels seperating Sibylla and Breje and walked the east shore of Breje to its northern end; we saw many small black tipped sharks, other Grouper-like fish and an octopus (about 3 ft.) while crossing channel ; we found an old airplane wing and a whale jaw on target plane) Breje; we left Chris on Sibylla when we crossed the channel - he returned to camp on west shore of Sibylla ; we started back from north Breje at East 1:15 ; we came down east side of both Breje and Sibylla through intermittent rain squalls; there are hundreds of Red-tailed Tropicbirds and Frigates on Breje and from what we could see on Kamone (over)
