Observation details

Photos attached. Correcting this report: Originally reported as Wilson's but on further review, I am changing the ID to Leach's Storm-petrel. Having several days to study both species more closely due to high winds, I can see the things that make this a Leach's storm-petrel instead of Wilson's are the fact that the carpal bar goes all the way to the leading edge of the wing, there is limited white on the rump patch, and it seems to be more V shaped at the top insead of straight across. The dark median line is not quite visible in the photo, but the white patch is definitely more limited than Wilson's. I had thought there were trailing feet beyond the tail in one photo, but looking again, it looks more like the side of a forked tail. Also in the photo of it pattering on the surface, the legs seem much shorter than Wilson's, and if they were folded up would not appear to extend beyond the tail. I am eliminating band-rumped due to the fact that the carpal bar extends all the way to the leading edge and should not do so on BRSP. My other original notes still apply: "Seen from the end of the fishing pier. Small dark brown bird with white rump patch and pale bars on wings. Flying near the surface of the water, pattering then flying 20 yards, then pattering on the surface again. Watched for a while more distantly, eventually it came closer and flew around the end of the jetty rocks. Generally moving northward. There may have been two but it is difficult to track when they get behind waves."
