Observation details

one or more visible during most of the hour (and into the next hour); views generally short at any one time due to high seas, but multiple individuals were often seen together, with all four seen together investigating an apparent mola shattered by a sea lion (what we call a gull scrum); the birds were fairly close for a land-based seawatch, but estimate of closest approach was about 290 meters (measured on Google Earth); all birds were similar enough to each other that I here describe them as one; medium-sized (considerably smaller than BVSH), dark storm-petrels with obvious white rumps (could not discern dark divider, though this feature was discernible in pix); long, narrow wings giving a falcon- or nighthawk-like appearance in flight due to obvious bend at wrist in nearly all wing postures; obvious and well-defined ulnar bar extended from innermost ss all the way to the wrist with no diminution of paleness or definition at wrist; white of rump wrapped around sides of rump onto underparts; tail, which was blackish and notched or forked, appeared relatively short compared to the long wings giving a heavy-fronted appearance; the tail was black and strongly notched; at least two birds were molting remiges, having reached the inner and middle primaries, respectively;
