R Brown 1966 Bristle-thighed Curlew Day 20 Only a few individuals of this species were noted. There was some tendency preference for the grassy areas about the central region, but individuals could be seen anywhere about the island, including along the open beach, especially rocky areas. Entire population at this time is probably less than 60. 10 June count = 51 R Brown 1966 Sooty Tern Day 20 This was by far the most abundant species on the island. The breeding area is essentially the same as that utilized last year; i.e., continuous nesting along the entire west side of island and port, west end wherever brunch grass (Eragrostis) is present. Within this past area two concentrations were noted: 1) quite heavy centration near the N and S some cover about 150 yds of the main landing. There were on fresh egg. 2) A very heavy concentration, about the entire SW end throughout grass cover. This concentration apparently started first toward the N as there mostly have eggs, and worked south and then E where large numbers areas yet without egg, many setting in large masses in the openings. Throughout the rest of the west side are scattered birds in varying densities, most with egg. The actual area utilized fluctuates greatly with seemingly little regard to actual grass cover available; i.e., the birds are not spread over the entire bunch grass area. Small colonies are located about the rest of the island, on the E and N sides. One colony is
