June 2 - cont. - Borneoland Petrel - found 2 dead chicks Red-Tailed Tropicbird - found only nest w/ eggs and I estimated 115 in 100 nests for my area, though the figure should probably be higher. Great Frigatebird - I estimated 168 nests, (probably lower for my area) 602 eggs, 10% bro. 15% med 15% lar. - upon closer examination many of the birds believed nesting were probably roosting. Brown Booby - I found only 2 nests : 1 egg, 2 am. chicks Blue-faced Booby - I estimated 83 nests - 25% E, 25% bro. 15% med 35% lar. - none of these nests were found inland, but along the Nari Dad Fisted Booby - I counted 229 pets which contained about 50% E, 25% bro. 10% med 15% lar. Sitt. Tern - I found only one small colony (ca. 20d) in the area I covered though there are many, many more Sothern Frigatebirds. Gray B-Skin - I found only 5 colonies - est. 30d total nests Common Tern - as a speculative estimate for the area I covered : 12,000 W.C. Tern - ca 150 nests, ca 500 roosting birds for my area in years. Fairy Tern - commonly seen, though in small numbers ca 300 In my opinion, this survey was undertaken too short a time for accurate estimate. I received much criticism from Bob Dedong & Chris Thompson for the beastness of my memo book. I felt much was unjustified as I wrote my results & figures in my journal. I also noted that I could not understand their books which contained little data and little sense to use. I told them if they did not believe my figures that they should get drilled. Tonight we witnessed a Green Turtle laying eggs directly in front of camp. She never took all night. We bled ca 125 Blue-faced Boobies and 25 Red Foot
