13 Jan. On board the "Golden Bean" off Baja Calif. Sea very much warmer and calmer this A.M. but the birds started oil very much the same as last night. I watched from about 6:30-7 and 7:30-9 AM, mostly from the bows during the first session saw 2 "Xantus" Murres, at at the very beginning of the period, one at the very end, a 1st year Herring gull which stayed around only for 10.5 minutes, and a all dark Puffinus diurea. A few flying fish about. After breakfast very little about until about 8:30 when Dr. Orr spotted a 4 Fregata magnificens circling high in the E horizon. And approach the boat. About 8:30 seemed there were some petrels following the boat and went back to see what was there. About 6-8 Black Petrels were following about 200-300 yards and further behind the boat, showing a slow, deep straining stroke and alternating with a glide, wing pointed down. Stood stiff like a black Tern. Hard to judge size. When garbage thrown off the boat its petrels will congregate about the floatsaw, alighting on the rails, usually for only a short period of time, and often with the wings only half closed. They circ back and forth across this slick behind the boat & seldom come as close as the turbulence from the propeller. A lot of the petrels becoming bored with the lack of organisms to see but still good attendance
