The image quality isn't great due to the light conditions, and the taxidermy quality is worse, but I like this shot
Obviously an accurate guess at labelling them would be impossible in the circumstances, unless you happened to make a note of any signage, but worth a crack anyhow for my own amusement......
Top Row (left to right):
Burrowing Owl (Athene cunicularia)
Boreal Owl (Aegolius funereus)
Spotted Owl (Strix occidentalis)
Elf Owl (Micrathene whitneyi) - not 100% on this one, it might be a pygmy owl.
Northern Saw-whet Owl (Aegolius acadicus)
Long-eared Owl (Asio otus)
Northern Hawk-owl (Surnia ulula)
Western Screech Owl (Megascops kennicottii)
Eastern Screech Owl (Megascops asio) - not 100% on this one.....
Bottom Row (left to right):
Snowy Owl (Bubo scandiacus)
Barred Owl (Strix varia)
American Barn Owl (Tyto furcata)
Great Horned Owl (Bubo virginianus)
Great Grey Owl (Strix nebulosa)
There were teeny tiny signs by each owl but I didn't write it down as I would have definitely have been confused and I wasn't going to take a picture of every sign!
