R.Clapp 1964 Oct. 17 Bikar Atoll Spent the morning banding Red-tailed Tropic- birds on Arumeni and explored the inner part of the forest. Both rats (exulans) and hermit crabs (Coenobitus perlitus ?)(sp.?) are found on the heavy damp litter floor but the hermit crab populations of both Taongi Atoll and Bikar Atoll are much more scanty than they are in the Phoenix Islands. Ken and George spent the morning banding Sooty Tern chicks while Binion collected insects and Lehner pressed plants for the ever-observant eye of the cameraman. Earlier in the day I had my chance to do a bit part for the camera and I did a short (but I trust well acted) rendition of "Banding the Red-tailed Tropicbird" in color yet. In the afternoon after returning to camp for a snack at twelve I banded for a short time on Jaboerruku (Tropic-birds), returning thence to cmp to prepare specimens. (Two Blue-gray Noddy (which I collected with the aid of a stick this morning), a Wedgetail, and a young Crested Tern collected by Binion this morning. Later in the afternoon we relaxed somewhat and several of the party (Lehner, Amerson, and Huber) went skin diving. Huber collected a live tiger cowry from the reef between Arumenii and Jaboerruku. In the evening banded Masked Booby, Brown Booby and Sooty Tern chicks.
