This is an Elf Owl.
He is very tiny, I guess. According to Wikipedia, “it is the world’s lightest owl. . . . The mean body weight of this species is 1.4 oz. These tiny owls are 4.9 to 5.7 inches long and have a wingspan of about 10.6 inches.”
And here is another Great Horned Owl:
I drew a Great Horned Owl on April 29th as well. I wasn’t going to do repeats until I had drawn one of EVERY OWL ON EARTH but then this guy came up in my bird-a-day calendar so I drew him. He looks as though he has something to say. (I think he is also probably a dark morph. My bird-a-day calendar doesn’t give very much trivial information though, so that’s just me spit-ballin’.)

Great Horned Owl is unimpressed with life. Also, I capitalized all three words of Great Horned Owl, thanks to your other blog post. But seriously, Great Horned Owl is dissatisfied with my accomplishment.
