I could see no evidence of surface organisms even when the birds were quite close. After completing a run they would rise up, with the flutter flight, little more on and repeat, a circle back with a slightly slower wing beat, of the same form. The stroke seemed to be about 2/3, and the tail was normally closed except as the birds flew. When the birds were going for- the water ward the legs were dropped frequently, espec- ially before feeding; coming back the legs were against the tail and often hard to see. In flying they were T like this, almost straight down. The white belly were very difficult to see, usually only when the birds turned. Birds feed "solitarily" (= spaced 5 to 15 ft. apart) for the most part, but sometimes closer and often one bird closely followed the path of another. Once saw one appear to "supplant" another, without portining a agression. Compared to the Petrels they were smaller, with shorter rounder wings, and a lighter black-brown with a much narrower tail band. The Petrels flew 2-3 ft off the water, seldom going down, and with a slower wingbeat showing a different motion than the Oceanites, 000 in stead of 00000 motion of the tip, perhaps with of the tip, too much a barely perceptible pause at the
