Half Moon Bay at sea

"But more surprising was that in this flock of 800 or so Ashy, there were plenty of Blacks, and amazingly a large number of
Wilson's Storm-Petrels. We were seeing them right and left, which is incredibly unusual, as a good day for Wilson's is just a handful. Instead that first flock had over 30 individuals, as well as a few Fork-tailed Storm-Petrels for our fourth Storm-Petrel of the day. An even larger flock a few miles off had a greater proportion of Ashy, but our Wilson's number climbed to at least 44, although we felt that there were likely over 50 of them in the area. This needs confirmation but seemed like potentially a record breaker number for California.
