To increase transparency, PeerJ operates a system of 'optional signed reviews and history'. This takes two forms: (1) peer reviewers are encouraged, but not required, to provide their names (if they do so, then their profile page records the articles they have reviewed), and (2) authors are given the option of reproducing their entire peer review history alongside their published article (in which case the complete peer review process is provided, including revisions, rebuttal letters and editor decision letters).
The manuscript is now suitable for publication.
Based on the Peerage of Science reviews and my reading of the manuscript, I find this interesting manuscript very close to publishable. It is very well written overall. My reading detected only a small number of errors in the use of punctuation and capitalization and a few lapses in the references and figure captions. The main ones are indicated below, and the rest are noted using highlighting and inserted comments on the pdf.
L63 and elsewhere. I think that 'parid' as an adjective should be lower case (check all mentions throughout manuscript).
References need to be checked for consistency in italics for species names, capitalization of journal titles, lower case for article titles.
Fig. 2 The caption refers to number of acts but the ordinates on the panels are rates.
Fig. 3. The caption refers to mean +/- SE, but panel c appears to use box plots, based on medians and quantiles (that should be described).
Fig. 4. Again, describe what the box plots represent. In keeping with SI standard abbreviations, the caption and axis label should abbreviate seconds as s, as elsewhere in the manuscript.
