Thank you for your review. We have expanded the discussion to address these points, however due to another reviewer saying the paper was already too long, we have kept this brief. A section detailing relevance to practitioners has been added to lines 545-551.
I felt the discussion about changes in greeting behaviour as an early indicator was interesting and could be expanded. Some more detail on the application of the findings to practitioners/owners would be beneficial. I do think this is of interest to a range of stakeholders.
