Suggestions for revision or reasons for rejection

Nishizawa et al have responded to the questions and suggestions of the reviewers quite well. On the easy stuff, they have made the changes, and on the more difficult questions, they have made what modifications that they felt they could. It is a disappointment that they did not attempt to query the North Pacific Pelagic Seabird Database, as it is now publicly available, and co-author Kuletz would have had little difficulty in getting the appropriate data extracted, particularly since she has been a major contributor to the NPPSD. The figures were missing from the material available to me. I am assuming that they have not changed since the first version.

The data in Table 1 show that shearwaters are not present in the Chukchi in June and July, but are there in August and September. The data in the Table, both for presence-absence and for density, do not support the conclusion of an exodus from the Bering Sea in summer. It is now 2016- do they have data from 2014 or 2015 that would strengthen the paper?

That said, the paper is a potentially important contribution. Their data on krill sizes by season and location are worth a paper in and of themselves, and the data on shearwater movements and habitat preferences are also a significant addition to our knowledge.

However, the paper needs a very significant editing- both for grammar, and for clarity. There are too many areas with convoluted sentences, mixtures of data and description, and awkward passages for this reviewer to feel comfortable with even a final evaluation of the merits of the science. I think that the paper is of more than sufficient scientific quality for publication, but I am not sure, as I did not follow the writing in a number of critical areas. Co-author Kuletz is a good and critical writer, and it is essential that she gives this paper a careful editing for both English and science content.
