Sorry, this is way beyond me. i do not understand this or what i am being asked. Please translate to plain English for me. thanks Gary.
@gary-james , looks like what was one owl species has been (easily)/split into two species. Easily, because their ranges do not overlap.
Are there visual cues to determine whether zoo owls are one species or the other?
Thank you. Now to find the difference to look for in the field and try to photo for records.
@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.
Yes, I live in Canada. And most likely the owl too;-) I look forward to the day or encounter when I experience an owl sighting and hear them call at the same time. They see and hear me more that I them. Thank you all for the feedback and comments. If I don't see them, I hope you do. Gary
Thanks! Good luck finding them!
I think this is the source of the split: https://archive.westernfieldornithologists.org/archive/V51/51(2)-p122-p128.pdf.
