Notes from Cornell

The eBird team at Cornell University tell me:

Because eBird is a global database and follows the Clements Taxonomy, our codes sometimes diverge from ABA bird ID (P4526) (which is restricted to the ABA region). As we manage over 10,000 species, there are inevitable conflicts in generating codes strictly following what ABA uses, we resolve those conflicts various ways but the result is the codes don't always align.

Birds of North America, Neotropical Birds, eBird, Macaulay Library and All About Birds all utilize the eBird species codes.

Birds of North America or Neotropical Birds do not cover vagrants like eurkes, as the two projects focus on breeding species within these geographic areas.

In the case of e.g. Osprey, the species level code is actually osprey; osprey1 is the code for the carolinensis subspecies, osprey2 is the ridgwayi subspecies. We sometimes use numbers at the end for subspecies and splits. So if ridgwayi becomes a full species, the code remains unchanged and will be osprey2. Codes don't change, regardless of common and scientific name changes or changes in taxonomic level.

The y00 codes (e.g. American Coot (Q470016) = "y00475") are where there were originally two different species and now the species have been "lumped".

A list of items with different values for P3444 and P4526 (430 of them, at the time of writing) is returned by this query:

SELECT ?item ?itemLabel ?ebird ?ababird WHERE {
  ?item wdt:P3444 ?ebird.
  ?item wdt:P4526 ?ababird .
  BIND(IF(?ebird != ?ababird, 'different', 'same') AS ?match) .
  FILTER(?match!='same').
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en".
  }
}

Try it!

Explore Species

Updated this for the new Explore Species feature (example). Makes this a very useful resource for bird species rather than only a link to a map. Innotata (talk) 18:11, 17 October 2018 (UTC)
