R.Clapp 1964 Oct. 10-12 Taongi Atoll, Marshall Islands. Perhaps 400 Blue-faced Boobies occur on the atoll. Pre-breeding displays were seen by two pair behind the camp when we landed on the atoll. Most of the birds appear paired and there are very few nests. Only several immatures and no large young were seen by me. In banding 42 birds on the 12th I noted no subadults. Birds are scattered along both edges of the atoll in more open areas and in openings in the denser cover along the beach. Relatively small numbers of Brown Booby occur on Taongi. I estimate a population of 150 none of which appears to be breeding. A quick check of Great Frigate breeding stage on Sibylla Island on the 10th and 11th showed many with nests in the Messerschmidtia. Most frigate nests contained eggs. On a short tour of the southern end of Sibylla and the next islet to the south I found 23 nests of which 15 contained eggs, 6 contained large and medium young, and 2 contained small young. An estimated 4000-5000 frigates occur on this atoll. On the morning of Oct. 11 a female frigate and a white-phase redfoot took turns sitting on a nest. Several male frigates were seen which possessed the fully developed pouches of the adult male but possessed the white under-arts of the immature as well. An estimated 50 Bristle-thighed Curlew were seen on Taongi Atoll. Huber said that he saw a single Sanderling to the south of Sibylla Islet as we reconnoitered in that direction on Oct. 11. The bird was not seen subsequently. Wandering Tattler are as abundant on Taongi as any place I have ever seen them. It is common on the rocky reef on, the SE of Sibylla and on the islets to the south. I estimate 150 birds for the atoll.
