Unordered minor issues/typos

[agnesolin]

It's all looking really good and running very smoothly! Mostly have some very minor comments/ideas:

• seabirddietDB is potentially a bit long and prone to typos with the double ds (but still good as it is informative and perhaps a little bit late to change now?)
• In the documentation (https://annakrystalli.me/seabirddietDB/#) it says that 10 spp are included but I can only find 8 in the database?
• In the documentation it says "Duffy & Jackson" in the paragraph at the top
• I guess the end-date is the last year with data? Perhaps it would also be useful to have the last date of data entry (i.e. last date anyone searched for publications).
• In the dataset there are a few columns that seem a bit redundant/unnecessary (pred_rank, pred_valid_name, pred_valid_aphia_id)
• There is a typo in entry id=2018 for endyear (should be 1987 I think?)
• The category "adults& chick" is a bit unclear - is this a mix between unknowns and when there was actually both adult and chick diets in the sample? Might be good to distinguish these?
• Very minor but in the documentation you highlight that freq_occ does not need to sum to 1 and that freq_num should so might be good to mention that freq_bio should also sum to 1?
• Related to the above issue: from what I can tell there is no clear id that identifies which entries e.g. freq_bio should be summed over? It is probably possible to figure it out based on sample size, ref etc but might be good to have a column for this included?

One additional thing I thought about was that it might be nice to be able to filter the dataset on higher taxonomic levels and get all the lower level entries as well? E.g. if I filter on "Ammodytidae" I would also get Ammodytes marinus etc (though we might want to have this as an on/off option so that it is possible to filter and get only e.g. the "Ammodytidae" entries). This is not necessary as all that information is in "classification" - so they could pull all lower level groups out themselves if they wanted - but would be a nice feature.

Hope this helps! Again, it's looking really good!
