This is a drawing of an Eastern Screech Owl (Megascops asio) of the “rufous morph” variety. The photo on which it is based was taken by a very nice man named Andy M¢ on Flickr who kindly gave me permission to use it in this artwork (here is the original photo).
Thanks to advice from the talented artist Glendon Mellow, I switched to using mechanical pencil for this drawing instead of traditional wood-encased lead pencils. The level of detail I can get is significantly better with the more-or-less constant diameter mechanical drafting pencil, and will be even greater once I buy a smaller diameter (I used 0.5mm for this one, but kept wishing I had a smaller one).
Side note: in high school, my zoology teacher Mr. Bob Ross once took our class out to the woods around Beaver Lake in Arkansas. There he taught us to actually call screech owls (as well as barred owls). I can’t call the screech owl very well any more, but I can still do a good barred owl. Mr. Ross was also one of my primary inspirations to eventually get my Ph.D. in biology.
