Hi -
One important thing about last year's BV Shearwater influx: it was thoroughly
telegraphed. That mass of birds was tracked north in California from seawatch
place to pelagic trip to seawatch place all the way from Monterey area, so that
observers up and down the Oregon coast were waiting expectantly. This year no
such northward surge in California was seen.
This does not explain what the birds were responding to, but it does highlight
that the causal factors for vagrancy tend to be where the birds come from, not
where they come to.

Subject: [obol] Question on BV Shearwaters
Another issue I am wondering about: There are only 6 records by the ORBC as
well, and I see None from last year. I suspect many who saw these were a little
reticent to submit a report??? Is the committee delaying a decision on the mass
influx of last year? Also, why no sightings this fall? If ocean conditions are
such to bring the Ashy SPs north, is not this the same for brining these
shearwaters north, again?
