split into |
@gary-james , looks like what was one owl species has been (easily)/split into two species. Easily, because their ranges do not overlap.
@schnautzr It's a case by case basis. Some species are easier to ID while captive, while some have to remain at genus level or higher. Specifically for the barred vs. cinereous owls, I think it's safe to assume that if you're in the US or Canada, that the species is barred owl. They are visually similar, but differ in call if you wanted to be certain.
@gary-james Cinereous owl is only found in Mexico, so if you're in Canada, you'll only see barred owls.
I think this is the source of the split: https://archive.westernfieldornithologists.org/archive/V51/51(2)-p122-p128.pdf.
The maps were modified from the iNat range map following the Owl Pages: https://www.owlpages.com/owls/species.php?s=1745.
