5Fet on board Ecuadorian Patrol Boat off S Isabella Is, Galapagos. flies with a jerkier wing wingbeat and the wing seems to be held farther below the body than above. Later in the day saw a little fluttering but not much. They flew lower to clear as the sun went up. Very few birds along the SW part of Isabela, mostly Puffinus lherminieri. Saw 1 nice ad. Red-billed Tropic bird flying over the boat. A few small rain squalls and constant overcast. Much salt spray, raining on Isabela. Most of the few Boobies here are dacrylactia. Slept a lot. Petrels about 1/2 x 1/2 O. quetzal and O. tethys, the latter was unmistakably dispensed than gracilis. Saw a Penguin about dawn before we got to Tortuga Is. No Tropic birds here this time. Very few birds from here on until we got well into the channel between Santa Cruz & Isabela, when, c. 1 hr. before we began to see " ", we saw large #s of Northern Phalarope, sitting on the water and spinning a little. Almost no petrel here but large #s of Audubon Shearwaters mixed with them and feeding, more or less singly, although it was by no means uncommonly to flush bands of 8-10 Puffins. They fled from a rapid flight, about same wingbeat as O. gracilis but wings stiff and stroke cccc. shallower, c. 1/3 wing length, and less gliding. fly 4-5 feet off the water for 10-15 feet when food plumifled, and drop down quickly, without circling, holding the wings horizontally out, or a little closed; only head under the water most of the time but the birds will dive in 1 sec. when necessary,(near the boat) see- flume facing and flying off almost immediately after.
