it's more likely domestic goose hybrid (Anser anser domesticus × Branta canadensis) in most cases, especially outside wild Greylag Goose range

Anser anser domesticus is a subset of Anser anser, therefore calling domestic geese Anser anser is not incorrect.

But yes, all observations outside Greylag Goose range would almost certainly represent hybrids with domestic geese

if you are not going to add Anser anser domesticus × Branta canadensis, I will agree the ID for the observation concerned is domestic goose, rather than adding Hybrid Anser anser × Branta canadensis, as domestic geese often are in fact part hybrids
btw first character in Branta should be capatalized in scientific name

Hi @birdison, you have flagged the entire taxon, not any specific observation.

"btw first character in Branta should be capatalized in scientific name"
Yes, unfortunately that is an error with iNaturalist, not with the person who created the taxon. iNaturalist forces taxa to be "sentence case," that is, without any capital letters except for the first one. The developers are aware of this issue but have not taken any steps to fix it (low priority).

Yes that's a good point. But note that Domestic Goose in iNaturalist is also explicitly Anser anser, so shouldn't be used for birds with hybrid ancestry. eBird has the option domestic goose sp. x Canada Goose. (i.e. Graylag and/or Swan x Canada). I'm not sure if iNaturalist can support that kind of hybrid. It definitely doesn't seem to support something like domestic goose sp. or similar "taxa", which is unfortunate.

@bouteloua should I have flagged the observation to ask you to add a different hybrid ? i didn't even know I could...

and I wouldn't have commented on the scientific name, if it wouldn't read Hybrid Anser etc. which made me think it wasn't "sentence case"

Oh, no, common names have different rules than scientific names on iNaturalist.

"I will agree the ID for the observation concerned is domestic goose"
Sorry, I must have just been confused -- it sounded like you were referencing a specific observation.
