| Notes | The download source page offers three taxonomy documents. I used the
master or integrated version as named on the download source page.
The eBird taxonomy does not supply a list of all the subspecies in the form I want to use, namely Genus species (subspecies). To generate the list in that form, I delete all the names with category family but keep all names in categories domestic, form, group (polytypic), hybrid, intergrade, slash, species, and spuh unchanged. For names in categories subspecies and group (monotypic), I take the English name category and add the subspecies epithet in parentheses. I get the epithet from the last word of the scientific name field. There a few times when the above method resulted in conflicts. For example, the polytypic group Australian Boobook (Boobook) contains a subspecies of Australian Boobook called boobook. My method results in the subspecies being named Australian Boobook (boobook) which differs from the polytypic group name only in capitalization, and since I do case-insensitive comparisons, these two distinct eBird entries appear as one. So far I have only seen this issue with polytypic groups. So I renamed the polytypic group to Australian Boobook (Boobook Group). I also renamed Baglafecht Weaver (Baglafecht Group), Coal Tit (Atlas Group), Correndera Pipit (Correndera Group), Sabota Lark (Sabota Group), and Slaty-tailed Trogon (Massena Group). |
