| | Encountering Seabirds & Marine Mammals in the Eastern Pacific |
 | | In the very deepest water, we encountered Herald, Henderson, Juan Fernandez, Gould's and Stejneger's Petrels with regularity, whereas we found Galapagos, Defilippe's and Cook's Petrels to be more abundant slightly closer to the continent Defilippe's and Cook's Petrels tended to occurs farther south than the others and primarily in the Humboldt Current. |
 | | As might be expected, Galapagos Petrel, Madeiran Storm-Petrel and Galapagos Storm-Petrel were most numerous in the vicinity of their nesting islands, although surprisingly they were sometimes encountered well away from the Galapagos Islands as well. |
 | | At this time of year, Defilippe's Petrel were in active molt allowing easy separation of this species at a distance from the fresh and unmolted Cook's Petrels. |
