Many obs. Photos. Regular in these waters in April. Observed on a cruise ship from LA to Vancouver, and observing birds with Paul Lehman, Scott Terrill, and about 8-10 other birders. Scott and Paul were obtaining and coordinating the GPS coordinates for hourly segments that were recorded throughout the day. These petrels were observed by multiple experienced pelagic birders, and we saw over 20 that day. Dark gray Pterodroma petrels that are expected at that part of the Pacific, distance from shore, and time of year. It is the expected Pterodroma species at this time/location. Similar species must be confirmed by close examination and may require photos. To my knowledge all we observed were Murphy's. Dark gray above, medium to light gray below, separated from dark Fulmars by profile, plumage pattern, and flight patterns.
