Another single sighting occurred on 9 June between French Frigate Shoals and Laysan Island. The flock of 5 were seen clearly as they flew along out of gun range above the ship. Sooty Tern Medium to high daily totals were recorded each day throughout the Leeward chain except on 25 June offshore Kauai, where only 10 birds were seen. Disregarding this low day adjacent an island with no breeding Sooty colonies, we have an average of 354 Sooties per day throughout the rest of the cruise.
