Long-eared owl look like a cartoon owl to me. The only one I've ever seen was here in Pennsylvania, USA, but it was so buried in a pine tree you could barely see it. Your photo shows them so nicely!
I saw what a guide told me was a Mottled Owl in Costa Rica. But it is different than the Mottled Owl featured in this course. Are there a lot of species of Mottled Owls? I wonder which one I saw? Here it is.
