Heads up: Some or all of the identifications affected by this split may have been replaced with identifications of Accipiter. This happens when we can't automatically assign an identification to one of the output taxa. Review identifications of Accipiter gentilis 5108

Taxonomic Split 133052 (Tehty 29-10-2023)

American Goshawk Accipiter atricapillus is split from Northern (now Eurasian) Goshawk A. gentilis (Clements 2007:43)

Brief summary: North America now has its own species of goshawk, adults of which differ in several ways from its Eurasian relative. Identification will not be impacted except by the possibility of an extremely rare vagrant.

This one is pretty straightforward. Everything looks good, so I'm committing.

Yeah I thought so too

@donalddavesne I also added the new distribution maps, so we're all good there too.

@birdwhisperer Oh I'm not sure how to do that! Would you mind pointing me towards a tutorial? I need to do it for a few fish taxa

@donalddavesne Download QGIS and download the distribution from iNat to adjust for splits. I'm thinking about making a video tutorial because it took me 2 days to relearn the system.

Have you got a link to any published rationale for this split? This is the first suggestion I've heard that the two forms are field-diagnosably distinct.

This follows the update of world bird taxonomy from the Clements checklist (used by eBird and iNaturalist) : https://www.birds.cornell.edu/clementschecklist/introduction/updateindex/october-2023/
The split is also widely accepted e.g. by the International Ornithological Congress (https://www.worldbirdnames.org/bow/raptors/)

@duncan-brooks The American Goshawk is the most distantly related species in the goshawk superspecies. That was main rationale for the split because if they weren't a species, why should species like the Black Goshawk or Henst's Goshawk keep their species card? The two are pretty easy to separate in the field, and though American Goshawk is a good descriptive name and I love it, we missed out on the opportunity for Vermiculated Goshawk to describe its main plumage trait. They're also pretty different vocally.

Ta. Good to know they're pretty easy to separate in the field.
