Observation details

With the FTSP aggregation near the 50 fathom line, rough location is 47N and 124 35W. Observed at 0755. Had the bird in view for a couple of minutes as it flew past the boat, hovered over the wake for a bit, then flew past again before it disappeared. The skipper, Phil Anderson, maneuvered the boat to keep the bird in view as it was not moving very fast. Excellent viewing conditions, with calm seas so the bird was in the view the entire time it was in our vicinity. Overcast skies, no glare. Numerous photos. BT notes - As we were enjoying the FTSP show, one of the participants called out that they had a dark storm petrel with a white rump. I was able to get on their bird immediately, and noted the extensive white on the rump wrapped around onto the sides. I immediately called out Wilson's Storm-Petrel and attempted to get everyone on board on the bird. I noted a dark, almost blackish storm-petrel with extensive and brightly white rump that continued onto the sides almost to the undertail coverts. Flight was fairly direct, with relatively shallower wingbeats than nearby FTSP. Wings are broader in shape than nearby FTSP. When it hovered over the wake, the long legs dangled very obviously. I did not make any notes on carpal bar.
