R.D. Brown 1868 Red-footed Booby (Sula sula) 7 Oct. Hondulah north to 20°41'部; 158°23'W 169 recorded from 1500 until sunset 1878. All light phase adults, similar 7 minu- des, usually no single accompanied by an adult. 07°45'NU: 166°56'ews - 05°57' all; 168°03' as 11 Oct. I showed up tonight right at sunset and began circling the ship; 5 imm. and one adult. I suspect since we are still about 500-600 miles N of Madagascar, the recent island, that these birds are winter (= a non-breeding, pre-breeding) resident of the rich feeding area at 20°5'公. Although very few other birds were about to indicate this, I feel that the presence of many of these red- footed individuals (very large, bulky) suggests feeding. Continued observation (1 hour) for 3/4 hr. after sunset failed to show any indications of feeding flocks. 03°57' cánh; 169°10'W - 01°58'W; 170°37'W 12 Oct. Saw several (5 th) immature, thought out the day, all singles. More paid attention to its ship as did C, B last night. R.D. Brown 1868 Red-footed Booby 16 Oct.

The nesting area here is more or less dictated by the Sula sula growth since all nests are in Sula. The marked nest area is around the large W wall near camp. 20 Oct. 2030 123 posting in huge central people plot well portion, at least 20 of these minim.
