Bratley, D.A. 1965 Sand Island, Johnston Atoll (Notes) Mar. 20 (cnt) Brown Booby — 3 birds seem to be incubating on one nest as I have caught 2 males + one female incubating over a period of time. The nest, #28, will be checked daily now to see which is the true pair. Also a female captured on nest #35 yesterday was on nest #35 today, which is only about 4-5 feet from #25. The nest #35 is not a built up nest as is the usual, but a single egg has been laid upon the ground. It may be that the female laid the 2nd that not in nest #25 where it belonged. This egg was numbered for nest #35 today for the egg was not there yesterday & we had numbered up to #34 yesterday. Mar. 21 Sooty Tern — Watched an adult kill a young chick which had wandered into its territory. The adult grasped the young by the nape, shook it, pecked it in the body's head, repeating such in a random method until after the chick was dead. Examining the chick afterward, the skin was broken & the internal organs of the abdomen could be observed. The skull, from which I took the body's had further tucked to distal 3/5nds of the head from jailing the small bird. Mar. 23 Sooty Tern — Observed plot #2 from 1200—
