Subject: [obol] Re: Black Storm-Petrel
In our first spring re-positioning cruise off the Oregon coast, we (Rich and Nanette Armstrong, Owen Schmidt, Sheran Wright, and I) saw a hug number of storm-petrels over about 75 miles off the southern Oregon coast. The only time I have seen more was in the Humboldt Current off South America.

Leach’s were everywhere, and there were lots of Fork-tails. We had a small flock of Ashy in front of the ship for an extended period of time, and Nannatte Armstrong spotted and I saw a Hornby’s. More relevant to this discussion was a fairly large all black storm-petrel, whose identification I was never satisfied. There were no Blacks being seen off California, due to the time of year. I will always wonder if it was a Tristram’s. Our looks at it were not ideal, but it certainly wasn’t an Ashy.

>> When Lars stared "there at least as many Laysan albatrosses in the world as black-footed" he was correct but that does give true picture. The Laysan population number is around 1,180,000 birds with 90% nesting in the NW Hawaiian Islands while the back-footed world population is around 139,000 with 95% of them nesting in the NW Hawaiian Islands. Hard to believe we don't see more Laysan offshore here but they just don't come this way in numbers.
