De Breezelli 1964 30 17 Jan on board "Golden Bear" en route to Galapagos. beat faster. Saw 5 white rumped Oceanodroma, twice 2 together, too far off to be sure of, 1st session at 9; every telling what they think they will do on the islands. Booby still with us.

Began observing again about 4:30 to 5:30, but saw everything within 5 minutes of 5. First a large, white bellied shearwater which flew with stiff wings, not angled at the carpal.
