During fellowship and shortly afterward, I spent some time moonlighting at a one-bed emergency department. (Yes, a single bed. It was great!) One can only study so much while stuck in a call room waiting for patients to roll in, so I spent some of that time improving my freehand drawing skills by sketching birds from photos I found online and in magazines. These graphite sketches–made with a clutch pencil–are shown below.
The cardinal and the golden jackal were drawn on a Boogie Board (an LCD tablet).
