18 May 2024

The San Diego pelagic trip on 18 May sponsored by Buena Vista Audubon Society aboard “Legacy” out of Mission Bay went out to the 9-Mile Bank, San Diego Trough, 30-Mile Bank, and “The Corner.” Ocean conditions were excellent, with light seas and a high marine overcast all morning. Large numbers of several species were noted in the waters from about 4 miles offshore out to the 9-Mile, with smaller numbers farther out. Especially impressive totals included the 20 Blue Whales, 115 Scripps’s Murrelets, 3000 Sooty Shearwaters (including one bird with a fully white head and neck), and 6 Brown Boobies. The two Common Murres were scarce and getting late.
